If you're in Japan, you have an alternative to air conditioning units and portable fans when it comes to staying cool in sweltering temperatures: a human-sized refrigerator that you can sit inside when the heatwaves get too much.

This is the Do Hiemon Box from Trusco Nakayama (via The Japan Times), and it'll blast your body with air cooled down to a refreshing 5°C or 41°F — about the same temperature as a chiller in a standard refrigerator.

It requires no installation, can be moved on wheels, and according to Trusco Nakayama it beats other solutions by cooling the entire body down evenly. After 20 minutes, the unit automatically switches off to prevent overcooling, and you're back out into the heat.

As per The Japan Times, a couple of hundred of these units have been sold across construction sites, golf courses, leisure facilities, and university campuses since the chamber went on sale earlier this year.

It'll cost you

You need a standard electrical outlet for this to work, and you also need access to the 1.5 million yen it costs (that's about $9,480 / £7,040 / AU$13,460). These personal cooling machines don't exactly come cheap.

The idea is that you get quick, temporary protection against heat exhaustion and heatstroke — a growing problem in our warming world — rather than using this as an air conditioned office or a space to relax in.

According to a Trusco Nakayama executive speaking to The Japan Times, enquiries about the fridge have come from as far afield as Germany and the US. The company is hoping to find more business at summer festivals and shopping malls.

Before long you might find yourself queuing up for a slot in the human fridge as well as for the loos at your next festival trip — another depressing sign of the consequences of climate change that show no signs of being reversed.

The Dreo TurboCool Misting Fan 765S has an advantage over traditional fans. While traditional fans provide what feels like a cooling breeze in the sweltering heat, they don’t in fact actually cool the air around you. That’s where the Dreo's clever misting technology comes in, reducing the temperature inside your home.

The brand claims the 765S can drop the temperature in a room by up to 6 degrees Celsius (roughly 11F), which makes all the difference when the mercury is rising.

It’s not the only misting fan on the market — for example the Shark FlexBreeze sits proudly atop our best fans list as I write this — but with super-quiet operation and bold room-cooling claims, can Dreo topple it from its top spot? I’ve put the 765S through its paces to find out.

Setup is pretty simple, but do take a moment before you remove the fan from its packaging. You need to remove the weighted base plate first, then prop the fan tower up on the edge of the box so you can fix the base to the bottom. It clips onto the bottom of the tower and is secured with a screw, included in the box.

There's a variety of protective packaging around the fan that needs to be removed before operation, including cardboard and plastic in the water tank. It’s worth taking your time to check you’ve removed all the various stickers, plastic film and cardboard protection — I did miss a couple of things initially.

Stand it up, plug it in and then setup is ready to be completed via the free Dreo app. App setup is as easy as the physical. Create an account, pair the app with the fan, enter your Wi-Fi password, and you’re good to go.

And the app is pretty good: it's clearly laid out, although it only offers basic controls (on/off and timer) on the main screen. For any deeper controls, you have to tap the picture of the fan. It’s not difficult, but I’d like to see a few more options without having to tap into another menu.

Fortunately, you're not solely reliant on the app, as there are touch controls on the top of the fan, plus you get a remote (and the two AAA batteries required to power it) included in the box.

With the remote, you can control the power, fan speed, fan mode, oscillation, misting and timer. It feels a little cheap in the hard with a basic plastic shell — Dyson’s remotes are far more premium, plus they magnetically cling to the top of the firm’s fans — but it’s functional and feels sturdy.

It’s annoying that there’s just one fan speed button on the remote though, forcing you to cycle through all speeds levels to get your desired one. I’d rather have up and down buttons for faster control.

When filling the water tank, it slides out from the front of the fan, and comes with a fold up carry handle to make transportation easier. You might think you don’t need it as you carry it empty to the sink, but once filled to the max level line you’ll find it surprisingly heavy. If you have a shallow sink, you might find filling a little cumbersome due to the size and shape of the tank.

The 765S's design is sleek and modern, with a pillar shape that tapers towards the top. The circular display on the front is bright and easy to read, even from across a room.

And at the bottom of the tower the water tank itself hides a fun feature. Power the fan on and you’ll notice a funky ambient light. It’s not just decorative, as the color can indicate the current humidity in the room. Blue signals humidity of 70%, while orange means the air is dry, at 30% or less. Green signals a comfortable humidity between 30% and 70%.

However, you can just have it illuminated in a color of your choice instead, with no link to the fan's performance or the room’s humidity.

There are three other lighting modes to choose from: constant, breath, and cycle. Constant allows you to pick a color of your choice for the light to be, while breath will see your color selection slowly pulsate. Cycle, as the name suggests, will cycle through a range of different colors, fading from one to the next. I found this to be a handy party mode when I had guests over and we were listening to music.

But what’s it like as a fan, I hear you scream? The good news is: pretty darn good.

At fan speed two, you can comfortably feel a breeze from four meters away, and it’s very quiet at this level, making it perfect for chatting with others, working, or watching TV. Even at its highest speed (12), I got a peak reading of 65dB directly in front of the machine, which is equivalent to normal conversation. It’s quieter than that when you’re sitting away, allowing you to speak to others without the fan being a distraction.

When it’s warm and you are looking for a breeze to take the edge off, this is all you really need. Higher fan speeds are useful when the fan is placed in larger, open-plan spaces, while the misting function is only really required when the mercury starts to soar.

But when the temperature does rise, the misting function is excellent. There are four misting vents — two on each side of the main airflow vent that runs down the middle — and they’re angled slightly up so moisture is directed into the air, rather than at the floor / furniture.

And it surprised me in two ways. Firstly, there’s hardly any increase in noise when the misting function is on, which means you could leave it on overnight in your bedroom and not be disturbed. Second, I was impressed with how fine the mist produced was. The ultrasonic atomizers used in the 765S produce a 17um ultra-fine mist — this means it evaporates quicker, preventing damp building up on objects nearby.

I could sit comfortably just a meter away from the fan, enjoying the cooling breeze without a sensation that it’s lightly raining. What’s even better is the misting function actually delivers on the claim that it reduces the temperature in your room.

During my tests, I saw a degree knocked off the room temperature after just 10 minutes of misting. It instantly makes a difference, and I was able to set a target humidity so the fan wouldn’t just keep pumping out water unnecessarily.

Keeping the fan running continuously for several hours, room temperature dipped by another degree, but I never saw more than a 2C drop during my weeks of testing. That’s some way off Dreo’s “up to 6 degrees” temperature reduction claim, and I’m not sure what sort of ideal scenario is needed to achieve this in the real world.

Still, a reduction in temperature is always a win, and the misting adds an additional layer of cooling, keeping me comfortable in what otherwise would have been a stuffy home office.

Dreo says the 6L water tank will last for 24 hours (or more) of run time when the misting mode is enabled, and I’m inclined to agree. I ran the 765S with misting turned on for a variety of different durations, and even during longer four to five hour sessions the water level reduced only marginally.

One slight frustration though was the limited oscillation angle. The 765S can only rotate 90 degrees. For many that’ll likely be enough, but having recently tested the Dyson Find+Follow Purifier Cool that has 350 degrees of movement, the Dreo feels a touch restrictive.

If you live somewhere hot and dry, the TurboCool Misting Fan 765S will provide all-day misting without breaking a sweat. Dreo claims the TurboCool Misting Fan 765S can reduce temperatures by up to 6C and although I didn’t get this level of cooling, it did make a significant difference in the rooms I tested it in, making them far more comfortable to work, relax, and sleep in.

It’s not going to deliver the same cooling as air conditioning, but the 765S offers an excellent middle ground between AC and traditional fans. It can genuinely reduce the heat in the room, keep humidity at a comfortable level, and does it all so quietly you might even forget it’s there.

How I tested the Dreo TurboCool Misting Fan 765S

• Used the TurboCool Misting Fan 765S for several weeks
• Tested in rooms of varying size and temperature
• Tried out the various modes, including misting

I used the Dreo TurboCool Misting Fan 765S for several weeks in my home, testing it in rooms of varying size and temperature. I used it in my lounge to see how effectively it could cool a modest room, had it running overnight in the bedroom to experience how loud it is when sleeping, and in my open-plan kitchen/diner for large space use.

I used the included remote, the free smartphone app, and the on-device buttons to find out how easy it was to control. I also used the misting function in the day and at night to test its cooling credentials.

Jake Dyson didn’t join his father’s business immediately; instead he set up a workshop and made a name for himself in the world of industrial lighting. Sitting in his office, I asked whether his experience in that sector had contributed to his work at Dyson today.

“Yes, it comes down to identifying problems and solving them,” he explained. “When LEDs first entered the market, I realized people weren’t cooling them properly. The promise of LEDs is that they should last a lifetime, but in reality they were being treated like disposable lightbulbs. I visited Osram in Asia, and they explained that if you keep the diode temperature below about 50C [120F, you can maintain brightness, color quality, and lifespan. That became my goal.

“I looked at how satellites manage heat. In space, temperatures swing from extremely hot to extremely cold, so they need precise thermal control. I applied similar thinking by designing systems that passively dissipate heat. For example, the heat moves away from the chip and is cooled by airflow, maintaining a stable temperature even at high power. That process, spotting a problem and solving it, is what drives everything.”

That problem-solving approach has always been the driving force behind the Dyson brand, and explains its unusual portfolio of products; its engineers have never been afraid to venture into new areas when there’s a problem to be solved.

“Sometimes it comes from frustration," said Jake Dyson. "'This product is rubbish, how can we make it better?’ Other times it’s curiosity: ‘Why does this work the way it does?’”

Problem-first design

James Dyson’s book Invention: A Life of Learning Through Failure, describes how the problem-first process led to the creation of many of the company’s most iconic and recognizable products — starting with a humble wheelbarrow. Dyson and his wife Deidre were renovating a house in Gloucestershire, England, and wanted to create a garden, but the traditional tools proved frustrating.

“I used a navy barrow in anger and its limitations became increasingly clear,” writes Dyson. “Cement slopped out of it. Its tubular legs sunk into the ground. It was hard to steer. Its sharp edges damaged doorframes. The more I used it, the more I realized that nobody had really thought about these problems or bothered to fix them.”

After much experimentation with shapes, materials, and manufacturing processes, the result was the Ballbarrow: a molded plastic bucket on a steel frame, with the conventional wheel replaced by a pneumatic ball made from EVA (ethylene-vinyl acetate). This spread the weight of the load more evenly on soft ground, and was easier to maneuver than a wheel — and in bright orange, it looked unlike anything else at the time.

The product itself was a success, but due to a series of poor business decisions, Dyson senior eventually lost control of the company he had founded around it, Kirk-Dyson, and was ultimately kicked out by the other shareholders.

“I had lost five years of work by not valuing my creation,” he wrote. “I had failed to protect the one thing that was most valuable to me.”

It was a painful experience, but one he learned from as he pressed on with identifying and solving problems — starting with the creation of the first cyclonic vacuum cleaner, which he designed after realizing that dust bags don’t just serve to collect dust — they also act as filters that block airflow, drastically reducing suction power.

“I remembered the same clogging problem on the calico cloth with the powder coating in the Ballbarrow factory and the giant cyclone we had made to solve it,” he wrote. “What if I could develop a much smaller version and replace the clogging bag in a vacuum cleaner?”

Thousands of prototypes later (5,127 to be precise), he had the world’s first bagless vacuum — and a vast collection of patents to protect it.

Dyson’s understanding of airflow and cyclonic technology has informed almost all of the company’s subsequent products; but like the vacuum, each one started with a problem. The Dyson Airblade hand dryer was created to reduce waste paper towels; the Airmultiplier fan solved the issue of ‘choppy’ air from conventional fan blades; the Pure Hot+Cool purifier was made to tackle indoor air pollution; and the Supersonic hairdryer solved the problem of heavy and uncomfortable hairdryers with weighty motors.

In every case, the form of the finished product was dictated by the problem it was designed to solve — even if the result looked totally unlike established versions of the device.

“That’s why Dyson products often look unusual; they’re built around their function,” said Jake Dyson in his Malmesbury office. “They’re also beautiful. A hair dryer has a hole through it because of how the airflow works. Fans and other products expose their engineering principles through the way they look — we’re not hiding how things work, we’re expressing it.”

Creative color

Those unusual designs are often set off by equally unusual color schemes, which tend to highlight buttons, switches, removable canisters, and other functional parts.

“We have a team here, CMF, which is colors, materials and finishes, that look into the appearance but also materials of our products," said Jake Dyson.

The CMF team doesn’t just draw on experience from successful projects, but also failed ones like the cancelled Dyson electric car, which provided finish and material ideas for many of the company’s health and beauty devices.

Most recently, CMF lent its expertise to Dyson's first hand-held fan — the Dyson HushHet Mini Cool — which launched just in time for a series of heatwaves in the UK. It sold out almost immediately, and after testing it myself, I can see why; it’s compact, much more powerful than its closest rival, the Shark ChillPill, and more affordable to boot.

“We’ve seen strong demand [for the HushHet Mini Cool], and it’s one of those products where people don’t initially realize they need it but once they try it, they understand the value,” said Jake Dyson. “It’s designed to be reusable, not disposable like cheaper alternatives. I've seen people with the cheap plastic fans that break very [easily], but we wanted ours to be well engineered, durable, quiet and efficient.

“We’re working on scaling production, but demand has been very strong, so availability can sometimes be limited. That said, it is coming back to market.”

So what does the future hold? The company is investigating ways to use AI where it will actually add value, helping machines interpret data and make better decisions, and Jake Dyson says that "vision systems and new product directions" are the most exciting areas for him.

"We’ve historically been very strong in mechanical engineering motors, airflow, performance. But now, adding cameras and vision systems allows machines to detect what they’re looking at, understand it and act accordingly.

"That opens up entirely new categories of products and capabilities, so we’re moving from purely mechanical devices to machines that can see, think, and respond, and that’s where the next wave of innovation is coming from."

It'll be fascinating to see which problems the company will be looking to solve with those new technologies, and there's no way of knowing what the next generation of Dyson products will look like as the company expands into new areas. We'll just have to wait and see — but it's definitely not going to be boring.

The Dimplex FlexBlade isn't your traditional tower fan, although you can use it as one. It's bladeless, Dyson-style, so it delivers smooth airflow without the buffeting of a bladed fan.

The design is very flexible, enabling you to use it as a T-shaped floor fan, a vertical pedestal fan, or any angle in between. Air comes out of two wide vents, and those vents can be rotated 90 degrees in either direction so that you can have wider airflow or cool two areas simultaneously. That could be useful in shared spaces such as offices, although as the fan's stand isn't telescopic, one of you will get a cool back while the other gets cool legs.

The FlexBlade looks like it'll be extremely powerful but the strength of airflow drops off quickly with distance, so at full power with both blades pointing forward it felt like a breeze at three meters. It's fairly quiet, though, and delivers similar airflow and noise levels to our trusty Dyson Hot+Cool fan.

This isn't the most powerful floor fan we've tested by any means but it does move a decent amount of air and that flexible design makes it useful for multiple applications, such as the bedroom at night and home office or living room during the day.

Dimplex FlexBlade fan review: price and availability

• Launched June 2026
• UK only
• £199.99 (about $160 / AU$230)

With fortunate timing, the FlexBlade launched during a month of record-breaking heat in the UK. The Dimplex FlexBlade Multi-Directional Bladeless Fan launched in the UK in June 2026 with a recommended retail price of £199.99 (about $160 / AU$230). It isn't currently available in Australia, and Dimplex doesn't sell its home cooling products in the US.

I'm writing this as more really hot weather is toasting the UK, so I need to temper my usual buying advice with the fact that for many people the only criteria for a fan right now are 'will it cool me down?' and 'is it in stock?', to which the answers are yes and at the time of writing, yes. But I would point out that Dimplex dropped the price to just £123 for Amazon Prime Day 2026, so if you're not reading this in sweltering temperatures you can expect similar discounts in the cooler months when demand sags.

Dimplex FlexBlade fan review: design

• Horizontal and vertical adjustment
• Horizontal oscillation
• Simple but effective controls

I can't talk about the design of the Dimplex FlexBlade without addressing the elephant in the room, or rather the Shark: the Shark TurboBlade cooling fan, which seems to have inspired Dimplex's designers. Both have a propeller-esque T-shaped design with two independent, rotatable bladeless vents. Both can pivot from horizontal to vertical mode. Both project air up to 20 meters. Both have a magnetic remote control. Both have a quiet sleep mode. And both have multiple speed settings: 10 for the Shark and five for the Dimplex. I think the Shark is a little nicer looking, more flexible thanks to its telescopic pole and less top-heavy — the Dimplex wobbles a bit when you touch it — but it's also £50 (about $70 / AU$100) more expensive when it's not in the sales.

The FlexBlade arrives in six parts: the main motor unit, a two-part riser with a heavy base, and the two vents. It's simple and quick to put together – the only tool required is the provided Allen key for securing the base — and the remote attaches magnetically to the top of the unit so it's always handy.

Controls are kept to a minimum on the fan itself: power/speed, oscillation and timer. The remote is simple too, with the addition of dedicated speed up/down buttons, a full speed button and a sleep mode button to put the fan into its lowest power state overnight.

The T-shaped, two-vent design delivers a lot of flexibility. You can't adjust the 1.1m height of the main motor unit but you can position the two blades vertically, horizontally or in between, and you can rotate them independently up to 180 degrees to push air in two opposite directions at once. The rotating blades are a little stiff but not awkwardly so. The blade adjustments are manual but the fan itself can oscillate automatically, delivering horizontal oscillation of 30, 60 or 90 degrees.

Design: 4/5

Dimplex FlexBlade fan review: performance

• Oscillation and adjustable vents
• Quieter than similar rivals
• Best experienced reasonably close

The Dimplex promises airflow in excess of 6m/s with a 20-meter range and 90-degree sweep, but at full power with both blades pointed directly at me from three meters away it felt like a very mild breeze. At that distance and with the blades arranged vertically the remote control was very hit and miss.

The Dimplex is a bit quieter than the Shark – Dimplex's figures say it's 36dB at its lowest setting and 58dB at full pelt, compared to the Shark's 40dB to 66dB – but it still gets loud at higher fan speeds with the telltale whoosh we've come to expect from bladeless fans. It's not Dyson hand dryer loud at full power, though; it's more like a hair dryer on a very low setting.

I compared the Dimplex's airflow to two other room fans: a Dyson Pure Hot + Cool and a Meaco Sefte 10-inch air circulator. Both the Dimplex and the Dyson are bladeless and moved air a similar distance with similar noise levels, although the Dyson's wider diffusion mode made its output quieter at the expense of focused air. But the Meaco was quieter than both and delivered significantly stronger airflow across a large living room.

Performance: 3/5

Dimplex FlexBlade fan review: how we tested

I tested the FlexBlade for a week at my home in Scotland during July 2026's UK heatwave. Scotland escaped the worst, because while England boiled the temperatures here were milder, peaking at 27ºC / 80.6ºF. That's hot enough to need a powerful fan but not so hot that I was crawling into my freezer or taking cold showers fully clothed.

I work from home in a long downstairs room that gets sunshine from both directions during the day, and that means it's often warmer inside than out – especially in the evening, as UK homes are typically made to retain heat rather than reflect it. I tested the FlexBlade as a daytime fan in my living room/office and as a bedroom fan overnight to see if it could keep me cool during the day, cool my family in the evening and help me sleep better at night.

First tested July 2026

Dimplex makes lots of floor, table and pedestal fans, and the Rechargeable Cordless Desk Fan is designed to address one of their weaknesses: they can only go where your plug sockets or extension cables can go. This affordable fan works as wired one via its USB-C port but also includes a rechargeable battery delivering up to 15 hours of air, or around four hours at full speed. That means you you can take it into the garden on a hot evening or take it to your bedroom and run it overnight.

The Dimplex Rechargeable Cordless Desk Fan doesn't oscillate but you can tilt it vertically up to 90 degrees, and it folds down almost flat so it's easy to keep in a drawer or toss into a bag. There are four speed settings here but the high speed one is not recommended while charging, as it depletes the battery faster than the USB-C connection charges it.

The fan works well and is fairly quiet, but it does make a noticeable drone at all speed settings; on a hot day, running the fan at high was very distracting. Of course all fans make some noise, but as this is a small fan with a 6.7 inch / 17cm diameter and 5.1 inch 13cm blades, you need to have it close to you to feel the benefit. In my home office the Dimplex on quiet setting at half a meter distance was noticeably louder than a much larger air circulator running at 50% speed one meter from me. If noise annoys, this may not be the fan for you.

Dimplex Rechargeable Cordless Desk Fan review: price and availability

• Launched July 2025
• UK only
• £34.99 (about $50 / AU$70)

The Dimplex Rechargeable Cordless Desk Fan, model DXRCFN, launched in the UK in July 2025. It has a recommended retail price of £34.99 (about $50 / AU$70), making it the most affordable model in the current range of Dimplex cooling fans and about £10 more expensive than a similarly sized wired desktop fan. It isn't currently available in Australia, and Dimplex doesn't sell its home cooling products in the US.

This fan has been cheaper – it was £25.45 during Prime Day 2026 – but I wouldn't expect to see any price cuts during the summer months in the UK.

Dimplex Rechargeable Cordless Desk Fan review: design

• Supremely portable
• Finger-friendly grille
• USB-C charging

The design of the fan is rather clever. It's been made for maximum portability, folding in on itself to resemble a small squashed football for travel or storage. It charges via USB-C and takes about four hours to charge fully. Because it's USB you can charge it with a phone charger or power bank, which makes it a good option for travelling. The battery is sealed inside and is not user-replaceable.

In addition to its internal bladed fan there's a circular louvred grille on the front that rotates and enhances the airflow. Although it spins quickly, the front grille is finger-friendly and won't hurt you or a child if you or they touch it (although you can lock it in place if you don't want it to spin).

The Dimplex fan doesn't oscillate, but you can adjust its vertical tilt by up to 90 degrees by moving the fan section up or down. It stays put without having to be screwed in place. Controls are simple, with just two buttons: power and speed. There's no remote control and no smartphone/smart home features.

Design: 4/5

Dimplex Rechargeable Cordless Desk Fan review: performance

• Decent airflow for its size
• Four speed settings
• Distracting sound

There are four fan speeds — quiet, low, medium and high — and I found that for my home office desk the quiet setting delivered a nice breeze without making me feel like I was in a wind tunnel. High speed was a bit intense up close but worked well from a little further away. Dimplex recommends only using High when you're on battery power as it can still deplete the battery when you're recharging it; at its lowest, quiet setting I managed 14+ hours from a single charge.

The Dimplex moves a decent amount of air for its size and it's fairly quiet in terms of its overall volume, which ranges from 36dB to 43dB. However, it does make a noticeable and constant droning sound that rises in pitch as you increase the speed. All bladed fans make some motor noise, of course, but desk fans are designed to sit very close to you, which means any noise is much more noticeable. For me it was too distracting at any speed when I sat it on my work desk, although in the bedroom at its lowest setting it didn't keep me awake.

Dimplex Rechargeable Cordless Desk Fan review: how we tested

I tested this Dimplex fan for a week during summery weather as both a desktop fan in my home office, and as a bedroom fan overnight. Both locations are in my house, where indoor temperatures were around 69.8°F to 75.2°F / 21ºC to 24ºC during the daytime and around 66.2°F to 68.0°F / 19ºC to 20ºC at night.

First tested July 2026

The Dreo Smart Misting Fan 516S is a device that came to me when I needed it most. It was a sweltering day in the UK — a nation with little in the way of air conditioning, but lots of humidity. But as I sat there at my desk sweating profusely, my editor handed Dreo’s new misting fan to me, and I have to say, it’s been a lifesaver.

But what exactly is the Dreo Smart Misting Fan 516S? Well, it’s a device designed to deliver “mess-free cooling,” and is best-suited for desks and tables. I’ve spent the last three weeks with Dreo’s fan, and have used it at my desk, at the kitchen table, and even in a controlled testing space at Future Labs. And for the most part, it’s proved to be quite an impressive performer — though it’s not totally without its flaws. So, here’s how I’d rate my experience overall.

First of all, let’s talk about who this fan is for. In my view, this is best suited for someone who’s sat at their desk and wants a personal fan, but one they can also set on a bedside table on hotter evenings too. I’d not necessarily recommend it to keep the whole family cool on the sofa, though — it’s still pretty compact, and the fan head is relatively small, meaning you don’t get the huge amount of coverage that some of the best fans can provide.

So, how does the 516S fare when used at a desk? In my case, it was great. I found the mist setting to work exceptionally well, and it added a nice degree of coolness without making any mess or feeling too intense. There were 12 speeds to select, and it was easy to switch between the three mist levels depending on how hot I felt. What’s more, it can oscillate 150 degrees horizontally, up to 20 degrees up, and 10 degrees down, making it easy to tailor coverage to your specific space. Dreo states that the 516S can cool a room by 3C / 5.4F at a max speed of 8m/s.

Setting up misting is pretty straightforward too. Simply fill up the detachable 1.3L water tank, slot it into the fan, and you’re good to go. You have to flip the tank upside down before inserting it, and this can lead to a bit of minor leakage, but I never found this to be a big issue. The tank is also large enough to keep misting for hours on end — 12 hours, according to Dreo — and I never felt that I had to refill it too regularly. And if you’re not in a misty mood, then fear not — it’s easy to switch over to a fan only mode, which works nicely too.

Even when using the mist mode, I found the fan to run pretty quietly, which was especially useful when trying it out at night. I didn’t find it difficult to drift off to sleep with the fan at a middling speed, and it certainly couldn’t cut past my Sony WH-1000XM6 headphones when trying it during the workday. One caveat, however, is that the Turbo mode — for those who want maximum power — can get fairly noisy. This could frustrate some when trying to watch TV or listen to music, but the mode did still work well when I needed a thorough blast of cold.

There are a number of other ways to customize your experience, though, such as a timer, a humidity preference setting, and a child lock system. Such options can be accessed through a number of control methods: touch controls, a remote, voice commands, or a companion app. This level of versatility is always welcome, and the inclusion of Alexa and Google voice assistants is pretty neat, especially given the 516S’s modest price — more on that later.

I will say, however, that the physical touch controls are… a little temperamental. Sometimes I found myself pressing a button over and over again trying to get it to function properly. That’s pretty frustrating, and often pushed me to reach for the remote instead. It’s no dealbreaker, especially with the various alternative control methods, but it’s worth noting all the same.

Before we sum up, let’s talk about design. This fan is decent-looking, with an easy-to-clean plastic exterior, attractive lighting on the control panel, and a transparent water tank, so you always know when it’s time for a refill. There’s also a practical carry handle, and you can easily dismantle the fan if you need to make a fix. The power cable is integrated, and you won’t be able to use this fan wirelessly, but for the cost, that’s understandable.

Speaking of cost, the 516S will typically set you back $99.99 / £99.99 (about AU$140), which in my view, is a very fair price. Sure, there are cheaper options available in this size-class, but you get mess-free and effective misting, a wide range of speeds, and a wide number of control methods, all without having to break the bank. So if you’re looking for a fan to use at your desk, or a personal cooling solution while watching TV for instance, I think the Dreo Smart Misting Fan 516S is well-worth considering.

How I tested the Dreo Smart Misting Fan 516S

• Tested across a three-week period
• Made use of all settings and features
• Used at home and in a controlled testing space at Future Labs

I spent three weeks testing the Dreo Smart Misting Fan 516S, using it at home on my desk and the kitchen table, and even trying it in a controlled environment at Future Labs.

During this time, I tested out all of the various features, sifted through the multiple connectivity and control options, and made sure to try the fan both with and without misting activated. During the majority of the testing period, I was using the fan on high temperature days with high humidity, making for a natural and authentic testing process.

More generally, I’ve tested tons of gadgets here at TechRadar across the course of multiple years. I’ve covered home and lifestyle products, audio gear, video games, and more as part of our dedicated reviews team.

The Dyson Find+Follow Purifier Cool PC3 is the latest tower fan from the British brand, and it offers up not only excellent cooling with owl-like oscillation, but also air purification.

That makes the Find+Follow Purifier Cool particularly helpful for those with asthma or allergies when they don't want dust, pollen and other particulars floating round their home.

But the party trick here is in the ‘Find+Follow’ name, and it’s what sets it apart from its predecessor, the Purifier Cool PC1, while also kicking the Purifier Cool Formaldehyde TP09 to the curb.

This particular cooling and air purifying fan features a small camera that can identify people in its field of view, and then follow them round a room, ensuring the breeze is always directed where it’s needed.

It’s a good looking fan, but all this comes at a steep cost — $849.99 / £549.99 to be exact. With many of the best fans coming in at a lower price point, Dyson has its work cut out to justify the premium cost of its latest offering.

Things get off to a positive start with the fan arriving in suitably protective packaging that’s almost all cardboard — the main piece of plastic is a large bag over the fan itself. It’s easy to unpack, and setup via the free My Dyson app is straightforward.

You’ll need both Bluetooth and Wi-Fi enabled on your phone, allowing you to get the fan connected to your device, as well as your home network. I liked the ‘Getting started’ video in the How To section of the app: it’s just under two minutes long and walks you through the core functions of the fan.

Controls in the app are nicely laid out, with easy access to on/off, fan speed, and oscillation. There’s also auto and night modes, a timer setting to turn off the fan after a set duration, and the ability to switch from fan to diffuser mode, if you want to purify the air in your home without the main fan being active.

Shifting focus back to the fan itself, it stands tall with its large, oval bladeless design sitting atop a gold pedestal that hides the air purifying tech and HEPA H13-grade and K-Carbon filters. Dyson claims the filter “captures 99.95% of particles such as viruses and bacteria, as well as pollen, pet dander and mould spores”.

It not only cleans the air, but the K-carbon filter can remove smells and gases, handy if you’ve been over-enthusiastic in the kitchen and want to get rid of that burning smell. I found it did a pretty good job of getting rid of the burnt toast smell in the morning quicker than leaving it to dissipate on its own.

There’s a power button just above the circular display on the base of the fan, but Dyson doesn’t provide any further controls on the device itself. Instead you need to use the remote, which magnetically clings to the top of the fan for simple storage, or the app to adjust settings.

You can also link the PC3 to your smart home, allowing you to use Google’s Gemini or Amazon’s Alexa voice assistants to control the fan. Linking it to my smart home setup also allowed me to control the Find+Follow Purifier Cool from the Google Home app as well as the My Dyson app.

The display on the fan is subtle, and from a distance it can be difficult to read due to its small size, but you can get all the info displayed here in the My Dyson app.

You can adjust the information the display shows by clicking the ‘i’ button on the remote, allowing you to cycle through visuals for various data including; indoor air quality, indoor humidity, indoor temperature, and remaining filter life. It’s useful stuff, but it’s better viewed in the app.

I was particularly impressed with the range of oscillation on offer, with the ability to rotate 45, 90, 180, and 350 degrees. Pop the Find+Follow Purifier Cool in the middle of a room and it’ll reach almost every area.

This was particularly useful when it came to placing the fan in a bigger room, as the huge angle of coverage provides far more flexibility. In my large, open-plan living space I could position it towards the center and have it reach most areas — although there was one small shortcoming: the length of the power cord.

At 1.8m it’s similar to many other rival fans, but as there are 350 degrees of movement, this is a fan you might be more inclined to position further away from a wall outlet to get maximum benefit. I was able to plug it into my kitchen island, allowing it to stand well away from a wall, without the cord or an extension cable draped across the floor — but your home’s setup will be different, so it’s worth considering where you’ll be plugging it in.

Once on, Dyson’s clever bladeless design delivers smooth air flow that feels like a natural breeze moving through your home, rather than the harsh buffeting you get from some other propeller and tower fans.

Coupled with its quiet operation — especially at lower fan speeds — you might find yourself forgetting it’s even on. My partner questioned whether I’d left the back door open as she felt a breeze, but it was simply the Dyson’s caress of the air is so gentle that it didn't feel artificially generated.

In our open-plan living space, I needed a fan speed between eight and 10 to really feel the effect during the warm weather, when sitting around four to five meters from the fan. In my small office (16m²), a fan speed of three was enough to keep me feeling cooler, with the Find+Follow Purifier Cool positioned a couple of meters away.

At its highest speed setting of 10, the Find+Follow Purifier Cool was still relatively quiet at 40-60dB, allowing you to comfortably have a conversation without the need to shout over the noise. Halving the speed sees the sound generated dropped to 20dB (similar to a mosquito), while at its lowest speed I got a reading of around 15dB, just slightly louder than normal breathing (10dB). If you’re looking for a quiet fan, the Dyson Find+Follow Purifier Cool is a strong contender, but the Duux Whisper Flex 2 has it beat, just.

The quiet operation meant I was able to keep the fan on overnight in our bedroom, with the low level hum not loud enough to disturb my sleep. My partner is a lighter sleeper, and after an initial adjustment, they were able to sleep with it on as well.

And then there’s the Dyson's Find+Follow party-trick. Enable this mode by pressing the button on the remote or in the app, and the fan will scan the room looking for people. Once it’s detected a person, it’ll direct air flow towards them. Get up and move around the room, and the purifying fan will oscillate to maintain air flow in your direction. It doesn’t rotate particularly quickly, but it’ll keep moving until it picks you up again.

If you leave the room briefly, the Find+Follow Purifier Cool will wait patiently in a ‘dormant’ state for your return. The fan will continue, but movement will only resume when you re-enter the room and it picks you back up.

When there’s clear sightlines in an uncluttered room, the Find+Follow AI does a reasonably good job of tracking movement, delicately rotating as you move about. However, I found if I passed too closely and too quickly, it wouldn’t always continue tracking me, even though I was still within its range of movement. This feature works best in large, open-plan spaces where you don’t need to pass too closely to the fan itself. In smaller rooms, the AI tracking can struggle a little more.

In cases where you leave the room for more than an hour, the system will switch to Auto mode, where the fan’s sensors will adjust the settings to reach the target air quality for the room.

For those concerned about the privacy implications of this technology, Dyson says the: “AI vision system never identifies anyone and only detects presence. Images are processed instantly within the machine, deleted and never leave the device.” And you can turn off the follow mode at any point using the remote, app, or smart home voice assistant.

When it comes to maintenance, Dyson’s bladeless design makes things super simple, with the wipe of a damp, lint-free cloth all that’s required. You do need to keep an eye on the air intake holes on the base though, as I found pet hair from my two cats would build up over the course of a few days. Dyson suggests using a soft brush to remove this debris.

The Dyson Find+Follow Purifier Cool is a highly accomplished purifying fan with useful modes, impressive features, and a fun — if slightly creepy — follow mode that a subset of users will find beneficial. Though I wouldn’t say the addition of this tracking camera does enough to fully justify Dyson’s asking price.

I’ve no problem saying that if you have the money, and are looking for a true flagship purifying fan, the Dyson Find+Follow Purifier Cool absolutely delivers. It’s supremely easy to set up and use, while the performance matches other high-end multi-purpose rivals. But if you’re bulking at the list price, there are plenty of reasonably priced fans — and Dyson purifying fans without Find+Follow — that provide similar levels of performance for less.

Dyson Find+Follow Purifier Cool review: Price & release date

• Premium price tag of $849.99 / £549.99
• Costs considerably more than its closest rivals
• Available in the UK and US from June 2026; not on sale in Australia

The Dyson Find+Follow Purifier Cool has been on sale since May 2026 in the UK, and went on sale in early June 2026 in the US but it's unfortunately not currently available in Australia. You can buy it via Dyson directly and a number of major third-party retailers.

The Dyson Find+Follow Purifier Cool costs $849.99 / £549.99, making it one of the more expensive fan and purifier combos on the market. It’s not Dyson’s most premium purifier (that’s the Dyson Purifier Big+Quiet Formaldehyde), but it is the firm’s most expensive fan, nudging out the $499.99 / £399.99 Hot + Cool HF1.

While the Find+Follow comes with its eponymous following camera tech, that has added $300 / £100 to the retail price of the Purifier Cool PC1 it replaces. The PC1 is still available though and is generally discounted too, if you want similar cooling and purifying results without the person-tracking tech.

If you’re not fussed about the heating or air purifying features, Dyson’s cheapest comparable fan is the Cool AM07 tower at $399.99 / £349.99, although this older model is sometimes discounted.

How I tested the Dyson Find+Follow Purifier Cool

• Used the Dyson Find+Follow Purifier Cool for a week
• Used it in the bedroom, office and main living space
• Tested various modes, including Find+Follow and Sleep

I used the Dyson Find+Follow Purifier Cool at home in the UK during a week of very warm May weather (28-31C / 82-88F). I set it up in my open-plan living space, master bedroom, and small home office, to experience how effective it was in different locations.

I tested the range of modes the fan has to offer, including auto, sleep, and Find+Follow. I operated it with the remote, via the My Dyson and Google Home apps, and I even asked Gemini via the smart speakers in my home to adjust fan speed and turn the unit on and off.

The Coway Airmega 100 is a small, cylindrical air purifier. It's designed for rooms up to around 63 square meters, packing an impressive Clean Air Delivery Rate (CADR) of 244 cubic meters per hour and a three-stage filtration system (pre-filter, True HEPA and deodorization filter).

Design-wise, it's a compact white cylinder that's light enough to carry one-handed and small enough to sit on a desk or tuck into a corner. The touch controls on top are simple and intuitive, with an air-quality indicator ring that shifts color based on what it detects.

Performance is where this purifier really shines, though. It's remarkably quiet even for one of the best air purifiers, especially in sleep mode where it drops to just 20 dB, and the auto mode does a good job of ramping up when it detects something in the air. There was also a noticeable reduction in surface dust after a few days of running it, and cooking smells triggered the sensor quickly. While it won’t eradicate stronger smells completely as a purifier with pellet-based carbon filters would, it still performs brilliantly when it comes to everyday dust, pollen and pet dander.

As you’d expect, there are some downsides, though, such as a lack of any Wi-Fi connectivity or app control. A quick look at the Amazon reviews will highlight a number of reports of replacement filters being hard to source in the UK, and while build quality is perfectly fine, it does feel a bit budget in places. Nevertheless, at around £110 / $84 on sale, it represents exceptional bang for your buck.

Coway Airmega 100 review: Price and release date

• Available now
• List price: £109.99 / $83.99 / AU$199

The Coway Airmega 100 is available to buy now in the UK, US and Australia. It sits at the affordable end of the air purifier market, and even at its full UK RRP of £149.99 / $129.99 / AU$199, it undercuts most comparable models from Philips, Blueair and Levoit, and it's a fraction of what you'd pay for anything from Dyson. At the time of writing, the unit can be picked up direct from Coway for a sale price of $83.99 / £109.99.

Replacement filters cost a very reasonable £27.99 / $39.99 / AU$59, especially compared to the £69.99 you'll pay for the larger Airmega 350's filters. Coway says they should last around 12 months, though in dustier environments you may need to swap them more often.

One thing to flag: a few buyers have reported difficulty finding genuine replacement filters on Coway's UK site, with stock appearing to come and go. Filters are available on Amazon, but some buyers have reported sketchy availability from Coway’s official web store, so it's worth keeping an eye on this if you're planning to keep this long-term.

Running costs are minimal too. With a 25W motor, you're looking at pennies per day even if you leave it running around the clock.

• Value score: 4.5 / 5

Coway Airmega 100 review: Design

• Compact and minimal, fits anywhere
• Touch controls are simple and intuitive
• Feels a little cheap, and there are no carry handles

The Airmega 100 is essentially a small, white cylinder measuring just 8.66 inches / 220mm across and about 15.75 inches / 400mm tall. This compact size means it can easily sit on a bedside table, a desk, or the floor in a corner and, at 6.61 pounds / 3kg, it's light enough to pick up and move around to put wherever you need it with ease. The minimal white finish might leave a bit to be desired, but it’s nice enough and will blend in with pretty much any room without drawing attention to itself.

As for the touch panel on top, this is a straightforward design that makes it super easy to navigate, sporting haptic buttons for fan speed, sleep mode, timer, light on/off and a control panel lock. Wrapping around the 360-degree fan grille is an air quality indicator ring that changes color from blue (clean) through green and yellow to red (polluted), giving you a quick visual check on air quality status without needing to press anything. I found the whole thing easy to get to grips with, no manual needed.

If I had to pull out a negative, I’d say build quality is where the Airmega 100 lets itself down a bit. It looks nice enough from a distance, but up close the plastic feels a bit on the cheap side. It's not flimsy or poorly made; it just doesn't have that reassuring heft you get from pricier models. There are also no carry handles, which is a minor gripe given how light it is, but still feels like something Coway could have added without much effort.

Air is drawn in through inlets at the bottom and expelled upwards through the top grilles, so, like its bigger sibling the Airmega 350, don't expect it to double up as a fan. This device is for cleaning air, not cooling you down.

• Design score: 4 / 5

Coway Airmega 100 review: Features and performance

• Impressively quiet, especially in sleep mode
• Auto mode reacts quickly to changes in air quality
• Carbon filter won't tackle strong cooking smells

For such a compact air purifier at such a low price, the Airmega 100 performs surprisingly well. The three-stage filter (pre-filter, True HEPA and deodorization) does a top job of capturing dust, pollen and pet dander, and I noticed a genuine drop in surface dust after just a few days of running it in my open-plan living and dining room.

The auto mode is the standout feature here, though. With a built-in PM2.5 sensor, it’s able to monitor air quality in real time and adjust fan speed accordingly. Start cooking, spray some deodorant or disturb some dust, and the ring will shift color before the fan kicks in. Then, once the air clears, it’ll settle back down. It's properly hands-off, and works really well.

Noise levels are also excellent. In sleep mode, the Airmega 100 drops to a claimed 20 dB, and I can confirm it's near-silent. I ran it overnight in the same room and totally forgot it was there. Even on its highest speed, it's not what I'd call loud, topping out at around 52 dB — that's roughly dishwasher territory, so for a bedroom or home office it's ideal.

The one area where the filtration falls a bit short is when it comes to strong odors. The deodorization filter uses a carbon-coated fiber rather than the pellet-based activated carbon you'll find in pricier models. While it handles light smells and general stuffiness fine, don't expect it to neutralize strong cooking smells or smoke from a burnt pan. For everyday dust, allergens and general air quality improvement, though, it's perfectly capable.

As with its older brother, the Coway Airmega 350, there's no Wi-Fi connectivity, app nor smart-home integration on the Airmega 100. This means you can't check air quality stats remotely or control it from your phone. That's not ideal, although — unlike on the pricier models — it doesn’t feel as much of a missing feature here. Still, it still feels like something Coway should be thinking about, as a basic app showing air quality trends and filter life isn’t exactly a cutting edge feature these days.

Nevertheless, the purifier’s timer options (you can choose between one, two, four or eight hours) and the control panel lock are both pretty useful additions. And there's a mood-light feature that provides a soft glow for bedroom use, which is a nice touch.

How I tested the Coway Airmega 100

I used the Coway Airmega 100 for several weeks across different spaces in my home, from my home office to open plan living room and dining area. I tested all fan speeds and modes, monitored the sensor's reaction to cooking, dust and general household air, and assessed the build quality, noise levels, filter access and overall usability throughout.

The Blueair Mini Restful Sunrise Clock Air Purifier is a three-in-one device — technically a four-in-one if you include the built-in USB charger — that combines an air purifier, a sunrise alarm clock and a wake-up light in a single unit. It launched as part of Blueair's Sleep collection with a clear USP: rather than cluttering your nightstand with separate devices, one appliance handles the air quality, the light and the alarm. If you've been browsing the best compact air purifiers for a bedroom, the Mini Restful sits in a category of its own.

The purification uses Blueair's HEPASilent technology, which captures 99.97% of particles down to 0.1 microns — finer than a standard HEPA filter — and my hayfever symptoms were noticeably more manageable on mornings after I'd had the Mini Restful running.

It runs across three fan speeds plus a Night mode, covers rooms up to 33m² / 355 sq ft, and is QuietMark certified. The brand claims noise levels of 21dB on its lowest setting whereas my own tests averaged 32dB, much of which was ambient.

In reality, it's whisper quiet and I could easily run it through the night without disturbing my sleep. I even forgot to switch it off a lot of the time because it's so quiet, I didn't realize it was still running.

What makes it stand out most from other purifiers I've tested is the wake-up light: a circular ring below the touchscreen display that brightens gradually over 15–30 minutes before your alarm time. This is designed to mimic natural sunrise, and you can also choose from multiple alarm sounds via the app, including birdsong, soft tones, and rainfall.

This wake-up light is impressively bright for its size and the whole appliance's design is attractive enough for you to actually want on your bedside table. I tested the Blueair Mini Restful in summer so while it helped rouse me gently, it's hard to judge exactly how effective it would be in the depths of winter, say, when a more gentle wake-up is most needed.

At 11.8in / 30cm tall and just 2.36lbs / 1.07kg, it sits comfortably on a standard nightstand, and the USB-C port at the back means it can charge your phone too, saving you even more space by eliminating the need for a separate charger.

My biggest complaint about the Mini Restful is the Blueair app, which doesn't quite live up to the rest of the device's performance. When it works, it's great — intuitive and clean. Yet there's no way to track air quality levels, and during my review period there was often a lag between adjusting settings and the device responding. This became frustrating quickly. The connectivity dropped completely three times during the four weeks of tests and I had to fully reconnect to my Wi-Fi and phone.

For anyone who suffers from allergies and has been meaning to try a sunrise alarm, the Mini Restful makes a compelling case that one device can do all of it well. But even if you already own one of the best air purifiers on the market and a separate sunrise alarm, the Mini Restful makes a strong argument for consolidating. It will definitely feel like an upgrade.

Blueair Mini Restful air purifier review: price and availability

• List price: $199.99 / £169
• Available in the US and UK

The Blueair Mini Restful is available directly from Blueair US and Blueair UK, as well as from Amazon US, Amazon UK, Walmart and John Lewis. It has a list price of $199.99 / £169, which converts to about AU$280, but at the time of writing it's not available in Australia.

On purification alone, it's easy to find cheaper options. Blueair's own £79 Blue Pure Mini Max, the £59.99 GoveeLife Smart Air Purifier Lite and the £149.99 Levoit Core 300S are all strong compact options that cost less and if all you want is cleaner air in a bedroom, any of those will do the job well. However, none of them has a sunrise alarm or wake-up light. Nor do they charge your phone.

In fact, there is no direct equivalent on the market — no other purifier currently combines HEPASilent filtration with a built-in sunrise alarm and wake-up light in a single bedside device. This means the real question isn't how it compares to other purifiers, but whether it's cheaper and better than buying two separate devices.

On that measure, it mostly wins. The Hatch Restore 3 ($169.99 / £220) is widely considered the best standalone sunrise alarm clock you can buy, while a compact bedroom purifier like the Levoit Core 300S adds another $99 / £90 on top. That's $260 / £240 for two devices that take up more space, require two separate apps and two separate power outlets. The Mini Restful does both jobs for $199.99 / £169 in a single unit that sits comfortably on a bedside table.

The trade-off is that neither function quite matches what a dedicated device delivers. The sunrise graduation isn't as smooth as the Hatch Restore 3, and the purification coverage is limited to spaces up to 33m² / 355 sq ft. If you need serious room coverage or a flawless sunrise simulation, you'd be better served buying separately. But for a standard bedroom and anyone who wants to simplify their nightstand, the value case is very strong.

Replacement filters cost $29.99 / £24 and need changing every nine months — a running cost worth budgeting for, even though it's in line with most other comparable purifiers.

Blueair Mini Restful air purifier review: design

• Compact and attractive enough to earn its place on a nightstand
• Soft woven fabric exterior
• Touchscreen display doubles as clock face
• Controls can feel awkward at table height

The Mini Restful is one of the better-looking air purifiers I've had in my bedroom, which matters more than it might sound.

Most purifiers are designed for corners and shelves where nobody has to look at them. They're functional, but they largely earn their keep by blending in. The Mini Restful is instead designed to stand out, and Blueair has clearly put effort into the aesthetic. The woven fabric exterior, which is available in Coastal Beige or Midnight and can be removed and cleaned, feels closer to an Alexa speaker than a home appliance. For comparison, the Levoit Core 300S — a purifier I rate highly for performance — is a plain white cylinder that would look out of place on my nightstand.

At 11.8 inches / 30cm tall and 6.7 inches / 17cm across, it has a similar footprint to a bedside lamp, albeit slightly more imposing. It's taller than I had expected for something described as a bedside device and it's not as compact as I'd like (the Blueair Blue Pure Mini Max, for instance, is shorter and lighter) but it does fit comfortably. I could fit the purifier and my phone charger on my nightstand without it feeling cluttered.

At 2.36lbs / 1.07kg, it's also light enough to pick up and move without any effort. The cord runs neatly through the base and plugs into a standard outlet, and at the back there's a USB-C port for charging your phone overnight. This is easy to reach without having to move the unit, and it's one of those small additions that makes a real difference to how the product fits into a bedside routine.

All of the controls sit on the top of the device, arranged around a circular touchscreen display. The display shows the time, current fan speed and filter status at a glance, and is the main interface for adjusting settings manually. It's responsive and readable in low light and the icons are intuitive — power, fan speed, display lock and purification mode are all clearly differentiated. I found I could adjust settings without turning the main light on after the first few days of use. The display can also be locked via the app if you want to prevent accidental changes overnight.

Just below the display is the light ring — a circular band that serves as both the wake-up light and a soft night light. It's a smaller lit area than you'd find on a dedicated sunrise alarm like the Hatch Restore 3, which uses its entire face as a light source, and I was skeptical that such a narrow ring could produce enough light to actually wake me. It did, and it looked elegant doing so.

Setup is straightforward. The Mini Restful arrives in a simple box with the device, a cord and a plug — thread the cord through the base, attach the plug, remove the plastic cover from the filter inside and you're done, in under two minutes.

From there you download the free Blueair app, create an account, and connect the device to your home Wi-Fi. The whole process took me around five minutes, and the app walks you through each step clearly. It's here that you'll set your alarm times, choose your wake sounds, adjust the sunrise duration, and create purification schedules.

The one ergonomic issue I found is that having everything on top means you need to lean over to adjust anything manually when the unit is at table height. It's a minor inconvenience rather than a dealbreaker, and in practice I used the app for most adjustments after the first week, but it's not ideal. Overall, this is a product that has been designed with the bedroom specifically in mind, and it shows in almost every decision Blueair has made.

Blueair Mini Restful air purifier review: performance

• Powerful purification even on lowest settings
• Near-silent on Night mode and speed 1
• Wake-up light impressively bright for its size
• Sunrise graduation can be abrupt

The Mini Restful has two jobs to do — clean the air and wake you up gently — and it approaches both with more conviction than I expected from a device of this size.

I tested it over four weeks as my primary bedroom purifier and alarm clock, running it every night and monitoring air quality via the Blueair app each morning. I also measured noise levels at each fan speed using a decibel meter, and ran the sunrise alarm as my sole alarm throughout the review period rather than keeping a backup.

Starting with the purification. The HEPASilent filtration captures 99.97% of airborne particles down to 0.1 microns, which is finer than a standard HEPA filter, and covers dust, pollen, pet dander and most common allergens with ease. I suffer from hayfever and the review period coincided with peak pollen season, which gave me a useful real-world test. On mornings after running the Mini Restful through the night on speed 1 or 2, I noticed a genuine difference: less of the throat tightness and eye irritation I'd normally get.

To test the purification speed specifically, I sprayed deodorant directly at the unit for five seconds on both the lowest and highest settings, then timed how long it took for the air quality reading in the app to return to normal. On the lowest setting it took around 45 minutes to fully clear. On the highest setting it took just 12 minutes — a significant difference. The app's air quality history chart, which shows readings over the past 24 hours and 30 days, is useful for tracking these changes and gave me a clear picture of how conditions shifted.

On noise, the Mini Restful is super quiet. Blueair claims 21dB on the lowest speed; my measurements put it at around 32dB. This sounds like a huge difference but the purifier is almost inaudible, even in a quiet room. Speed 2 registers around 35dB, which produces a gentle white noise that actually helped me sleep rather than disturbing me. Speed 3 is noticeably louder at around 48dB — not unpleasant, but enough that I wouldn't choose to run it while trying to fall asleep. The Night mode handles the transition well though, stepping the fan down to its quietest setting automatically, and I left it on this mode for the majority of the review period.

Blueair says the Mini Restful works best in rooms between 14–33m² / 151–355 sq ft, which will cover most standard bedrooms. I tested it in a medium-sized room and found it kept up well, with the air quality sensor registering improvements within 20–30 minutes of switching on after a day with the windows open. It won't cope with large open-plan spaces — for that you'd need something with considerably more power, like the Dyson HushJet Compact — but for a bedroom it's more than adequate.

The wake-up light is the more interesting part of the performance story. The light ring is small relative to a dedicated sunrise alarm but on its highest brightness setting it lit the room enough to wake me without the alarm sound triggering at all on several mornings. The three manual brightness levels via the touchscreen are useful, and the app's slider control allows finer adjustment if you want to dial it in precisely.

The issue is with the graduation. The light is supposed to brighten gradually over 15–30 minutes before your alarm time, mimicking a natural sunrise. For the most part it does, and on the mornings it worked as intended the experience was gentler than waking to a conventional alarm. But on several occasions — I counted at least six across the four-week review period — the light jumped to full brightness abruptly rather than easing up to it, which is jarring. It doesn't ruin the experience entirely but it stops the Mini Restful from matching the consistently smooth graduation of a dedicated wake-up light. If the sunrise simulation is the primary reason you're considering this, that inconsistency is worth noting.

Elsewhere, the alarm sounds themselves are pleasant and varied — birdsong, soft tones, rainfall — and the volume is adjustable via the app.

Blueair Mini Restful air purifier review: app

• Required for full setup and alarm customization
• Doesn't show air quality levels
• Clean, well-organized interface
• Lag between app and device is frustrating
• No HomeKit, Alexa or Google Home support

Despite a small number of flaws, I can barely fault the hardware of the Blueair Mini Restful. The same can't be said for the app though, sadly.

Firstly, the Blueair app isn't optional. You can use the touchscreen to turn the device on and off and cycle through fan speeds, but doing anything of note, such as setting alarms, choosing wake sounds, adjusting the sunrise duration, creating purification schedules and checking air quality history, all require the app.

This is great when it works. The interface is clean and logically laid out, with the device status and filter life all visible without having to dig through menus. Setting a sunrise alarm takes seconds: you pick a time, choose a sound, set the brightness duration between and you're done.

The filter replacement reminder is useful; the display lock feature is a sensible addition for overnight use; and the scheduling tools are flexible enough to set different purification levels for different times of day.

However, knowing how to view live air quality readings isn't obvious, and I ended up having to Google for help. Even then, you can only see the current outdoor air reading (via the Outdoor air section on the homepage) and not a live, room-by-room chart.

Then there's the problem with lag. There was a consistent, frustrating delay between adjusting a setting in the app and the device responding throughout almost the entire review period. This could be anything from a few seconds to almost 30 seconds on occasion. Switching fan speeds via the app often took longer than just tapping the top of the unit, which defeats part of the point of having remote control in the first place.

What's more, during my four-week review period the connection dropped completely three times, requiring a full reconnection through the app each time. I'd find myself checking the app before bed to make sure the alarm was still set and the connection was still live, which is exactly the kind of friction a product like this should be eliminating.

The absence of any smart home integration is also a real gap. There's no HomeKit support, Alexa skill or Google Home compatibility, which means the Mini Restful exists entirely within its own ecosystem. For anyone who controls their bedroom environment through a smart home setup — lights, heating, other devices — the Mini Restful sits outside all of that. It's not a dealbreaker, but it's a limitation that feels out of step with both the price and what other, similar connected bedroom devices offer.

Blueair has clearly invested in the app's design and the range of features it offers, and the bones are good but the execution needs a lot of work.

Dyson’s engineers are experts in airflow — whether in vacuum cleaners, fans, or hair dryers — and the HushJet Mini Cool puts that power right in your hand. It’s a portable cooling fan that you can hold, wear around your neck, attach to clothing or a bag strap (if you buy one of the optional clip accessories) or stand upright on your desk — and it really works.

Shortly before testing the Dyson HushJet Mini Cool, I got my hands on the Shark ChillPill — a rival handheld fan that was released at approximately the same time. I was impressed by the ChillPill’s cooling ability, which is supplemented by a misting attachment and a metal cooling plate — but in terms of sheer power, the Dyson absolutely blows it away.

Watch the video version of this review below...

This mainly comes down to two factors: the fan’s powerful motor, which can reach up to 65,000rpm (compared to just 25,000rpm for the ChillPill), and the shape of the HushJet nozzle, which concentrates the airflow so it’s all directed right at you. Even on the lowest setting, you can really feel it; dial it up to maximum and it’s as powerful as some hairdryers I’ve used.

The sound is not unlike a miniature vacuum cleaner, but the HushJet shape works to eliminate the annoying higher frequencies that might irritate colleagues if you use it in the office, or fellow passengers on a busy commuter train. There’s even a hint of Dyson’s signature ‘bounce’ sound when you turn it off.

Accessories like a clamp (so you can attach it to gym equipment) are available to buy separately, but you get a neck strap included with the fan as standard. Slide this onto the fan (it has notches that allow it to slip past the control buttons), adjust the cord to a suitable length, rotate the fan’s head so it’s pointing towards you, and you’ll enjoy a cooling jet of air on your chest, neck and face, hands-free. Extremely handy if you’re taking stuffy public transport.

Dyson claims that the HushJet Mini Cool can run for up to six hours on its lowest power setting, but during my tests it significantly outperformed that figure, lasting almost exactly six and a half hours on a full charge.

It’s hard to fault the HushJet Mini, but a couple of things stood out during testing. Firstly, it’s easy to accidentally cover part of the air intake grille with your hand when holding the fan, which I’m sure affects its performance.

Secondly — and this is only my personal opinion — the Stone/Blush colorway makes the fan look like an exfoliating facial brush at first glance (not unlike the Braun Facespa Pro) which is a strange thing to wear around your neck and might raise a few eyebrows.

Dyson HushJet Mini Cool: price and availability

• Launched May 2026
• Available globally
• List price $99 / £99.99 / AU$169

Dyson announced the HushJet Mini Cool on April 9, 2026, and it was available to buy globally a few weeks later. It has a list price of $99 / £99.99 / AU$169, which is very reasonable for a powerful personal fan. For comparison, the Shark ChillPill, which went on sale just a few weeks earlier for $149.99 in the US, or £129.99 in the UK (which converts to about AU$210, though at the time of writing the ChillPill isn’t yet available in Australia).

The Dyson HushJet Mini Cool has been in high demand since its launch, and at the time of writing (June 2026) it’s often sold out in Dyson’s official online stores. The Stone/Blush colorway is sometimes the only one available.

If you’re not planning to use your fan on the move, and want one specifically for your desk, take a look at the Dyson Cool CF1 Desk Fan, which is just as quiet but can move a larger volume of air, oscillates and has a remote control, making it a better choice if you’re sitting still (possibly working from home). It has a list price of £249.99 (about $340 / AU$470).

Dyson HushJet Mini Cool: Design

• Unique shape for a portable fan
• Nozzle focuses airflow and reduces noise
• Neck strap and charging base included

Dyson devices often look slightly unusual, taking the most practical shape for their function regardless of how vacuum cleaners, hair dryers, or, in this case, fans have traditionally looked. The HushJet Mini Cool is no exception — with its slim, tubular body and angled nozzle (which is the same shape as that of the Dyson HushJet Compact Purifier), it looks nothing like other personal cooling devices, but it’s a shape that works. The body of the fan is comfortable to hold, and the nozzle can be turned to direct the airflow exactly where it’s needed.

The HushJet Mini Cool is bladeless (like Dyson’s larger fans), ensuring the airflow is smooth rather than choppy, and its honeycomb-like mesh keeps dirt and debris out of the mechanism — though it's also supplied with a soft velvet carry case to protect it on the move.

The HushJet Mini Cool comes in three colorways: Ink/Cobalt (dark blue), Stone/Blush (soft pink, as shown here), and Carnelian/Sky (red and pale blue). Personally I prefer the latter option, which is the most striking, and it seems I’m not alone — at the time of writing all colors are selling out rapidly, but Carnelian/Sky seems to be the one disappearing from the virtual shelves quickest, followed by Ink/Cobalt.

The tubular shape, with a flat end, means that you can easily stand the HushJet Mini Cool on your desk while you work. If you’re planning to use it all day, it comes with a charging base, which provides extra stability regardless of whether the USB cable is plugged in or not.

Whichever color you choose, the fan’s case has a satin finish that feels pleasantly smooth and cool in the hand and is resistant to fingerprints, with contrasting colors for the nozzle and buttons. Dyson’s car never took off, but the company’s designers took the knowledge they gained about finishes and materials, and applied it to beauty products — which explains why they look so smart.

How we tested the Dyson HushJet Mini Cool

• Tested for a week
• Used on trains, in the office, and at the gym
• Tested battery on lowest power mode
• Measured volume with decibel meter app

I spent a week testing the Dyson HushJet Mini Cool in various locations, including trains to work, at the office, and in the gym. I compared its performance directly against that of the Shark ChillPill.

I measured its noise level with a decibel meter app on my phone, and tested its battery life by fully charging it, then allowing it to run on the lowest power setting until it switched off. For more details, see how we test, review, and rate products at TechRadar.

First reviewed June 2026.

The Airmega 350 is a large-room air purifier from the South Korean brand Coway that's been quietly building a reputation outside the UK for over 30 years. It's designed to cover spaces up to a whopping 245 square meters, packing a CADR of 713 cubic meters per hour and a three-stage HEPA and activated carbon filter.

In terms of design, it's a clean, white cylinder that blends into most rooms without any fuss, topped with an intuitive touch panel and a color-changing ring that gives you a quick read on air quality. It looks good, though the plastic chassis does feel a bit cheap in places, especially the removable filter panel at the back.

Performance is where the Airmega 350 really stands out, though. It's remarkably quiet during everyday use, even compared to the best air purifiers, the sensor reacts fast to cooking smells and dust, and it cleared my living room noticeably within minutes of detecting something. Auto mode means it can run in the background completely hands-off, and Sleep mode means it can do its job while you're sleeping in the same room, since it's near-silent. I also noticed a real drop in surface dust after just a few days of running it.

The biggest downside in the Airmega 350 is the lack of any Wi-Fi or app control, which is a bit disappointing — especially at this price. You can't check stats, adjust settings remotely, or turn it off from your phone. It's also a big unit with no wheels and only one handle, so moving it between rooms isn't ideal. But if you value air-cleaning performance over smart features, the Airmega 350 is a powerful purifier that won't disappoint.

Coway Airmega 350 review: Price and release date

• Costs $249.99 / £254.99 / AU$699

The Airmega 350 is available to buy now in the US and UK. It sits in the premium end of the air purifier market, but it's not unreasonable for what you're getting. Even at its RRP of £299.99 / $339 / AU$699, it undercuts a lot of Dyson's range, sitting alongside comparable models from Philips and Blueair. What’s more, at the time of writing, the unit is on sale direct from Coway’s official web store in the UK and US for £254.99 and $249.99 respectively, making it an even better deal.

Replacement filters don’t come cheap, however, costing around £69.99 / $89 / AU$135. Coway says they should last over a year with normal use. At the time of writing, filters in the UK were available on Amazon UK but were sold out on Coway's UK site, which is a bit frustrating if you prefer buying from the brand directly. Coway says these will be back in stock soon, but it's worth keeping in mind.

• Value score: 4 / 5

Coway Airmega 350 review: Design

• Clean, cylindrical design that blends in with most rooms
• Touch controls are intuitive but feel a bit plasticky
• No wheels and only one handle for a unit this size

The Coway Airmega 350 is a tall, white cylinder that stands about 59cm high and 30cm across. It's not small, but the cylindrical shape means it takes up less visual space than a boxy purifier would, and the clean white, minimal finish means it doesn't demand too much attention, blending in well with most home decor.

The translucent touch panel on top is nicely laid out and intuitive to use. There’s buttons for mode, fan speed, timer (one, four or eight hours), a lights on/off toggle, and a filter replacement reminder. The color-changing ring around the panel shifts from blue (clean air) through green and yellow to red (high pollution), giving you quick visuals on what's going on without you needing to check a screen. Even without reading any instruction manuals, it didn't take me long at all to figure out what everything did, which is exactly how it should be.

I'll be honest, though: the unit’s build quality doesn't quite match its looks. The touch panel works well and is responsive enough, but the plastics feel a bit on the cheap side. The removable back panel that gives access to the filter clips off easily enough (perhaps a little too easily, actually) and has a slightly flimsy feel to it. It's not going to fall apart, but it does knock the premium impression down a notch when in the hand.

One thing worth knowing is that the purified air blows upwards out of the top, not outwards like a fan. So if you're thinking this might double up as a cooling device, it won't. It's a purifier, not a fan, and Coway hasn't tried to pretend otherwise here.

And finally, for those who might be looking to move this device around often depending on where they feel air purification is needed, it’s worth knowing there are no wheels on the base, and there's only a single carry handle on the back. For something this size, that's probably a bit of an oversight. On the other hand, it’s relatively light (just under 8kg) and so not too difficult to carry between short distances.

Coway Airmega 350 review: Features and performance

• Remarkably quiet, even on the most powerful mode
• Sensor is very responsive to cooking smells and smoke
• No Wi-Fi or app is a missed opportunity

Performance is where the Coway Airmega 350 really shines. Turn it on and the first thing you notice is just how quiet it is. On its lowest settings, it's genuinely hard to tell it's running. Even in Auto mode, where the fan ramps up and down based on what the sensor detects, the noise stays in the background. Sleep mode is practically silent, and I had no trouble running it overnight, even in the same room.

What’s more, when the sensor detects something specific it needs to react to, it does so fast. During use, I found that cooking smells from the kitchen would trigger the fan to kick up within seconds, with the ring shifting from blue to yellow or red, and within a few minutes the air would be noticeably fresher and the ring would settle back to blue. The same went for general dust and pet-related particles. It just gets on with its job quietly — you hardly notice it’s there.

The real star of the show, however, is the Airmega 350’s three-stage filter (pre-filter, HEPA and activated carbon). In my tests, I found this did a great job across the board. Coway claims it captures 99.99% of airborne pollutants, and while I can't verify that number, I can say that the amount of dust settling on surfaces in my living room was noticeably less during use. And when it comes to changing it, the filter itself is easy to access through the unit’s side panel, popping out without any tools needed.

I found that the Airmega 350’s four modes (Auto, Sleep, Eco and Turbo) cover most scenarios well. Auto is the one I used most, and it's genuinely impressive at regulating itself. Sleep dims the lights and drops the fan to near-silence, while Eco runs on low power until it detects something, then kicks in. Meanwhile, Turbo is for emergencies, like when you've burnt the toast, the smoke alarm is going off and you need to clean the air ASAP. It's louder, obviously, but I found it can clear the air super fast.

There’s only one major niggle in the Airmega 350, and that’s its lack of Wi-Fi and app support. In fact, there’s no smart home integration whatsoever. For a purifier at this price, that feels like a missed opportunity and it’s kind of expected for a device of this calibre these days, so it’s something I think buyers will miss. This lack of app support means you can't check air quality stats from your phone, you can't adjust settings remotely, and you can't turn it off if you've left it running and you're already out the door. It's not the end of the world, but it is an odd omission when Coway's own pricier Airmega 450 does have app connectivity. It feels like the 350 is being held back on purpose to protect the model above it, which is a bit annoying.

How I tested the Coway Airmega 350

I used the Coway Airmega 350 as my main air purifier for several weeks in an open-plan living room. I tested all four modes during my time with it, which included monitoring the sensor's reaction to cooking, dust and general household air, and assessing the build quality, noise levels, filter access and day-to-day usability throughout.

Dyson has launched what may be its smartest air purifier yet, the Dyson Find+Follow Purifier Cool. As the name suggests, it's a purifier that knows where you are and follows your movement, directing air to where you are and optionally turning itself off when you leave the room.

It doesn't just work for solo users. It can detect multiple people in the same room, automatically adjusting its oscillation to share the cooling "efficiently and evenly". By directing the air at people rather than just into the room, the Dyson Find+Follow Purifier Cool should be more energy efficient than less intelligent devices.

Dyson Find+Follow Purifier Cool: key details and pricing

It's worth noting that like similar Dysons, this is a fan rather than an air conditioner so it doesn't refrigerate the air; it just moves it around very well. If you're looking for a portable air conditioner we've rounded up the best in-stock options right here.

In addition to the people detection the Dyson Find+Follow Purifier Cool has a typically high specification. Its K-Carbon + HEPA filtration captures 99.97% of ultra-fine particles as small as 0.3 microns and promises to capture 50% more NO₂ than rival purifiers. It's fully sealed to HEPA H13 standard and has automatic sensing of PM2.5, PM10, VOCs, NO₂, and formaldehyde.

As ever with Dyson, the device is very impressive but the price is pretty high, especially in the US – although it's a little more affordable than first announced. The press release listed the price as $894.99, but it's currently available from Dyson.com for a slightly less frightening $849.99 / £549.99. That works out at about AU$1,190, but it's not currently listed on Dyson's Australian website.

High-end fans can move a large volume of air very quickly for maximum cooling effect, but even a cheap, low-powered fan can make a noticeable difference to the temperature indoors if you position it strategically — particularly at night when you're struggling to sleep in a stuffy bedroom.

Read on for three top tips for using your fan properly, and if you don't already own one, check out our guide to the best fans for our top picks, rated and recommended by our expert reviewers.

1. Know your fans

First of all, determine whether you have a fan or an air circulator. They look very similar, but they serve different purposes when it comes to keeping you cool.

Simply put, a fan blows a concentrated jet of air in your direction, which helps sweat evaporate and lowers your skin temperature. An air circulator, on the other hand, moves air around a large area in your home, and works best combined with some sort of cooling source, such as an air conditioning unit.

Meaco is one of the biggest names in air circulators, and its new Sefte Pro models are particularly good for keeping you comfortable at night. Our writer Becca Caddy recently reviewed the Meaco Sefte Pro 10in Table Air Circulator, and was very impressed by its whisper-quiet operation, and ability to run all night on a single charge. It even comes with a glow-in-the-dark remote so you can control it from bed. The pedestal version has its wireless receiver in the top so you don't have to sit up to aim the remote, and its mobile app lets you start running it while you're out, so you return to a cooler house.

If you want a fan (to use while working at your desk, for example), the Shark FlexBreeze gets our seal of approval. Again, it's extremely quiet, and it has a misting attachment that sprays a very fine cloud of water to enhance the cooling effect as it evaporates from your skin. You can also detach the head from its tall pedestal and use it as a desktop fan.

2. Position it properly

If you've chosen a fan rather than an air circulator (which is usually the less expensive option), you can boost its effectiveness at night by using negative pressure ventilation, which is a technique employed by firefighters to help clear smoke out of a room.

It might sound counterintuitive, but if you position your fan so it's facing an open window, rather than pointing into the room, it will draw in cool air from outside while pushing warm air out.

This method only really works to cool one room at a time, but it can be very effective. If you want to cool your bedroom, for example, close all windows and doors in your home except for the bedroom window, the bedroom door, and a window at the other end of the house from your bedroom.

Place your fan about 3-6 inches from the window, facing out of the room, turn it to its maximum setting, and switch it on. The fan will create negative pressure inside your house, and cause cold air to rush in through the opposite open window.

3. Keep it clean

Whether you're using a fan or an air circulator, it's important to keep it clean to keep it running efficiently and avoid spreading dirt around your home. It's easy to forget if your fan has been sitting on a shelf for months, but as the aircare experts at Dreo point out, it can make a big difference.

Fans and air circulators often come with removable grills to make cleaning easy. Switch off and unplug the fan, then look for the small screw or clips holding the grill together and undo them. Wipe the blades and grill with a damp cloth, allow them to dry, and then reassemble. You can also wipe the fan's housing with a dampened microfiber cloth, but don't get water anywhere near the motor. If you can see dust in air intakes, use a small brush to gently dislodge it.

If you're in any doubt about how to keep your fan clean, check the instruction manual and the manufacturer's website.

The Dyson HushJet Compact Air Purifier is Dyson's first dedicated small-format air purifier, and it's a notable departure from what's come before. Unlike the imposing, bulky tower fan-purifiers of old, the HushJet has been engineered to better fit into your home — or at least, that's the idea.

Yes, it's smaller than Dyson's current range, but it's far from tiny. It fits on a desk and kitchen countertop, but not comfortably or subtly, and its design makes it stand out rather than blend in. The black and blue colorway I tested looks out of place wherever you put it, while the star-shaped HushJet nozzle, which is inspired by jet engine aerodynamics, looks as industrial as its name suggests.

There are few controls on the device itself and Dyson is relying on people using the MyDyson app to monitor air quality and adjust settings. Thankfully this isn't a chore because the app is super intuitive and simple. Plus you also have the option to control everything with you voice, via Alexa, Google Assistant or Siri, if you'd rather not pick up your phone.

Also, in day-to-day use, the Auto mode does most of the heavy lifting anyway. Intelligent sensors monitor air quality in real time and ramp the fan speed up or down as needed, which in practice means the HushJet spends most of its time running almost silently in the background, only surging when something pollutes the air.

Inside the purifier, the electrostatic filter captures 99.97% of particles as small as 0.3 microns. This includes dust, pollen, pet dander, and mold spores. The activated carbon filter then takes care of gases and odors, including cooking smells and NO2 from gas hobs. Both filters come pre-installed, which makes setup refreshingly painless, and they have long shelf lives. The electrostatic filter lasts up to five years, while the carbon filter should only need to be replaced once a year, keeping the running costs down.

The jet engine design isn't just an aesthetic choice, it means that the HushJet can channel purified air into a "focused, high-velocity stream" that covers rooms up to 100m2 / 1,076 sq ft. Most homes won't need this, but it's reassuring to know that you can place this purifier anywhere in your home and it's got you covered. These numbers would be impressive for any air purifier, let alone one this size.

At $349.99 / £349.99 / AU$549 the HushJet is a significant investment, especially when you consider that it's a purifier only, with no fan or heating function to justify the spend. However, if clean air is a priority and you want the best compact air purifier on the market right now, it's hard to argue with what Dyson has built here. It sits at the top of its category, and in my tests it earned its place, but if that's beyond your budget check out our guide to the best air purifiers.

Dyson HushJet Compact air purifier review: price and availability

• List price: $349.99 / £349.99 / AU$549
• Available in the US and UK

Dyson's HushJet is available in the US, UK and Australia direct from Dyson, as well as Best Buy and Walmart in the US, AO and Very in the UK, and JB Hi-Fi and The Good Guys in Australia.

At $349.99 / £349.99 / AU$549, this is an expensive purifier by any measure. To put that into context, the Blueair Blue Max 3250i – our pick for best air purifier overall – is less than half the price, at $169 / £169. Even the Dyson Purifier Cool PC1, a larger purifier-fan combo from Dyson's own range, is only $100 / £100 more, and it adds fan functionality on top.

What you're paying for with the HushJet is essentially the miniaturisation of Dyson's purification technology, combined with the new HushJet nozzle and its impressively quiet operation. I believe its performance justifies a large part of this premium but there are very capable, significantly cheaper rivals that tick just as many boxes.

Dyson has become famous for its distinctive, often divisive, design choices, and the HushJet is no exception. Like most Dyson products, it's sleek, cylindrical and well-built, but also striking and bold — especially its star-shaped HushJet nozzle top, which is inspired by the aerodynamic principles of jet engines, and doesn't look like anything I've ever tested.

Whether that's a good thing will depend on your taste. In my house, it divided opinion: my partner loved the look of the black and teal colors, but I didn't. I found it too much for an appliance that's supposed to sit quietly in the background.

That tension between form and function runs through the whole design. Dyson calls this purifier 'compact', and relative to the brand's own range – which includes the towering TP09 or the enormous Big+Quiet – it is. But in absolute terms, at 18.5in / 47cm tall with a 9in / 23cm diameter, it's larger than the name implies. I tried it on my desk, on a bedside table and on my kitchen counter, and it felt imposing on all three. It ended up on the floor in most rooms, which undermines the compact pitch somewhat. For context, the Levoit Core 300S is half the height and is more subtle.

I typically like to move my purifier into different rooms, depending on my needs (for example, I put it in the kitchen when I'm cooking steak, or I put it in my son's room at night when the pollen count is high) and while the HushJet is technically portable, its missing carry handle makes moving it a little awkward.

On-device controls are minimal by design. There's a small LCD screen that shows air quality data — using a color-coded line graph — and current settings above a row of three physical buttons. These buttons cover most of the day-to-day changes you'll need:

• The fan button on the left lets you cycle between Night mode, the three on-board fan speeds, and Auto mode.
• The power button in the center turns the purifier on and off.
• The information button on the right cycles through the current PM2.5 levels, current PM10 levels, the state of the on-board filters, and the Wi-Fi details.

If you want to set schedules, change Auto mode's target particulate level, access the seven other fans speed, or access any other more detailed settings, you'll need to download the MyDyson app. You can also control the purifier using your voice and the HushJet works with Amazon Alexa, Google Assistant or Siri.

This is also where you can learn what each of the air quality colors mean:

• Good (green): very low level of microscopic particles
• Fair (yellow): moderate level of microscopic particles
• Poor (orange): high level of microscopic particles
• Very poor (red): very high level of microscopic particles
• Extremely poor (pink): extremely high level of microscopic particles
• Severe (purple): severe level of microscopic particles

Setup across the board with the HushJet is painless. Both filters come pre-installed, and connecting to the MyDyson app took me less than 30 seconds. It's one of the easier Dyson products I've set up, and it starts purifying the air immediately.

Dyson HushJet Compact air purifier review: performance

• Auto mode reaction times are unmatched
• Whisper-quiet on lower settings
• Limited app granularity
• Less impressive on smoke than VOCs

Given its price, and the fact it only covers purifying, the HushJet's performance needed to blow me away (excuse the pun) and thankfully it did.

I have a large open-plan kitchen-diner, as well as a substantial loft room, and even when the HushJet was placed on the opposite side of the room to where I was cooking, or spraying deodorant, its fans captured and cleared the particulates with ease.

During my aerosol tests, in which I sprayed deodorant at the purifier for five seconds while it was in different purification modes, the fan consistently took the air quality from as high as Severe to Good in less than a minute and a half. The low fan setting, unsurprisingly, took the longest at 1 minute 23 seconds (on average); the medium fan setting handled the particulates in 1 minute 2 seconds; and the high fan cleared the air in just 50 seconds. These speeds are unheard of in all my years of testing.

I also lit a match and let it burn out directly in front of the unit. Within three seconds, the HushJet had detected the drop in air quality and increased its fan speed. The app showed levels spike to purple before the purifier cleared the air entirely in four minutes. For comparison, the Blueair Blue Max 3250i, our top-rated overall pick, took 20 seconds to register the same drop, although it cleared the air slightly faster at two and a half minutes. Both are fast; the HushJet's sensing is simply quicker.

The one test where the HushJet was less convincing was dust. Emptying a vacuum cleaner's dust canister next to the unit hardly moved the dial at all. Granted, the vacuum in question was the Dyson Cyclone V10, which has its own filtration system, which may have captured most of the harmful particles before they reached the HushJet's sensors. But it was a less emphatic result than the smoke and VOC tests.

In terms of noise, Dyson advertises the HushJet at ranging between 24dB and 42dB. During my own tests using the DecibelX app, the lowest I recorded was 29dB on Night mode, with 55dB at the top end, on high. This is still whisper-quiet at the lower end, while the higher end is roughly the volume of a light conversation. What's more, the sound is soft rather than sharp ,which makes the HushJet sound even quieter in real-world use. So much so, I could have the HushJet on in the bedroom at night, with Night mode enabled or without.

Other good news is that the Auto mode's quick reaction times mean the unit rarely stays at full power for more than a few minutes.

When it comes to air purification, the HushJet uses a two-filter system: a 360-degree Electrostatic filter that captures 99.97% of particles as small as 0.3 microns, and an Activated Carbon filter for gases and odors including cooking smells, pet odors and NO2 from gas appliances.

I suffer from hayfever and during my review period I noticed a difference in my symptoms on days when I had the HushJet running. I can't say it got rid of them entirely, but on days when the pollen count was high and the HushJet had been running in my bedroom overnight, I woke up feeling better than I'd expected.

I didn't run the HushJet constantly during my review period. My typical pattern was to run it overnight in the bedroom on Auto mode, and then move it to the living room during the day when the pollen count was high or when I was doing anything likely to kick up dust. Over the course of testing, the electrostatic filter didn't register any degradation. Even after four weeks, it's still showing 100%.

The activated carbon filter, which promises a one-year lifespan, dropped to 96% so this will need replacing much sooner. A replacement electrostatic filter costs $64.99 / £50 while the carbon filter costs $44.99 / £35. This is worth factoring in but you won't need to spend extra for a while after purchase.

Overall, the HushJet does exactly what it promises. Its Auto mode is smart, its filtration is fast and its the quietest purifier I've ever tested. It's not perfect but in terms of performance, it comes incredibly close.

Dyson HushJet Compact air purifier review: voice control

• Easy to set up
• Works with Alexa, Google Assistant and Siri

Once the purifier is connected to your home Wi-Fi, it can connect to any Amazon Echo, Google Home or Apple Siri device on the same network at the press of a button through the MyDyson app. This app doesn't give you voice command prompts to get you started – like the Dreo app does – instead you'll need to go to the dedicated assistant app to learn how to speak to the HushJet.

That said, as soon as I got the hang of it, voice control quickly became my preferred way to control the HushJet day-to-day. I have an Amazon Echo in my bedroom and being able to ask Alexa to turn the purifier on or off, adjust the fan speed or check the air quality without reaching for my phone made a difference to how often I interacted with it.

On mornings when the purifier was downstairs, I could ask Alexa to kick the purifier up a level to remove the smell of my son cooking toast even while I was in the loft. Elsewhere, you can ask Google, Alexa or Siri to turn the purifier on and off, ask for a specific speed, set the purifier to a certain mode and check levels.

Dyson HushJet Compact air purifier review: app

• Offers a range of control options
• Color-coded design is intuitive and simple to use
• Near-live air quality data

The MyDyson app is one of my favorite things about the HushJet, and is one of the better companion apps I've used for home appliances. It's clean, well-labelled and easy to navigate from the first time you open it.

The home screen shows an image of your HushJet above the main menu, which includes Controls, Data and Insights, How To, and Product Settings.

Below the image are the quick-access controls for Auto mode and fan speed, plus an on/off toggle, a Night mode that dims the LCD screen on the device and quietens the fan, and a Timer option.

Your current air quality reading displayed in Dyson's color-coded system sit below this panel, followed by the Schedule option. This scheduling function lets you set the HushJet to run at specific times. I set it to run on Auto every morning before I got up, so the bedroom air was already clean by the time I woke up.

In the Data and Insights section you can see the air quality graphs broken down by PM2.5 and PM10 readings, all presented in the same color-coded scale. The current reading updates every 30 seconds, but the graph only shows average readings in 15-minute intervals. You can swipe back to see historical data but it doesn't reveal very much and lacks the granularity I'd like.

Elsewhere, the app doubles as a support hub, with how-to videos, filter life tracking, and the option to buy replacement filters directly. It's a small touch but a useful one, and you're unlikely to forget to replace the filters when the app is actively telling you when it's due. In Product Settings, you can connect the purifier to Alexa, Google Assistant or Siri, set the time, data and location data and manage the Wi-Fi connection. There's also the option to enable/disable continuous monitoring which is what's needed for the Auto mode to work effectively.

If there's one criticism, it's that the app is essentially non-optional. Anyone who prefers physical controls may find the HushJet frustrating to live with but for those comfortable with app-based control — and I'd argue that's most people buying a £350 / $350 / AU$549 smart purifier — it's an excellent companion.

How I tested the Dyson HushJet Compact air purifier

• I used the Dyson HushJet Compact air purifier and its partner app for four weeks
• I stress-tested it using different substances
• I experimented with different speeds, modes, and settings

I tested the Dyson HushJet Compact in my home over four weeks, during peak hayfever season. I used it primarily in my bedroom overnight on Auto mode, and moved it to the living room and kitchen during the day to test its response to different real-world air quality changes.

To test purification, I carried out a range of specific tests: lighting a match to create smoke, spraying deodorant to introduce VOCs, cooking on a gas hob to generate cooking fumes and PM10 particles, and emptying a vacuum cleaner dust canister to test dust response. For each, I monitored the HushJet's reaction time – how quickly it detected the change in air quality – and its clearance time – how long it took to return readings to normal. I tracked all air quality data via the MyDyson app.

Noise levels were measured using the DecibelX app across all fan settings. I also tested the voice controls by connecting the HushJet to an Amazon Echo while using with the MyDyson app daily.

First reviewed May 2026

Air purifiers are designed to capture everything from dust to pollen, pet dander, and even bacteria and toxic chemicals. Since using an air purifier with high quality filtration, I’ve experienced less allergen triggers and swollen sinuses at night.

Most air purifiers will bring some relief to allergy sufferers, but some are better than others. I’ve put together a list of the top three air purifiers that will reduce the effects of allergy season through various modes, smart features, and high-quality filters. Read on to learn more.

GoveeLife Smart Air Purifier Lite

The GoveeLife Smart Air Purifier Lite has a three-in-one HEPA Filter which includes a pre-filter that removes hair, lint, and fibers and a Personal HEPA filter that traps PM 2.5 and any other 0.1-0.3 micron particles such as dust, bacteria, dander, smoke, smog, ash, and pollen. Finally, an active carbon filter clears odors quickly.

For $50, you get quite a bit of features including app and voice control and four modes – sleep, low, high, and custom modes. With the custom mode, you can set the air purifier on high, low, or sleep mode for a certain amount of time. Unfortunately, the app doesn’t share air quality data, so you aren’t able to see how well the filter clears the air of things that could trigger your allergies. If you’re especially sensitive, you might want to set the purifier on high during allergy season and in the late afternoons (with the custom mode) when pollen levels rise. Thanks to its compact size, you’ll have no issue moving the air purifier to whichever room you’re in.

While the GoveeLife Smart Air Purifier Lite has an aromatherapy feature, our tester found the results underwhelming. This might not be a bad thing since some essential oils exacerbate allergies. That said, you might want to give the aromatherapy feature a try since peppermint and eucalyptus oils are known to alleviate inflammation caused by allergies.

Levoit EverestAir

Despite its high price tag, the Levoit EverestAir is a favorite air purifier among TechRadar testers. This slim purifier has the capability of purifying larger spaces thanks to three-stage filtration system, which includes a washable pre-filter that captures dust, pet fur, lint, and hair, an H13 True HEPA filter that traps dust, pollen, dander, and fine dust, and an activated charcoal filter combo that keeps your home odor-free. The vents are adjustable, so you have some control over the direction of the airflow.

Users can choose Sleep, Turbo, or Auto mode with the onboard buttons or an app. In Auto mode, the Levoit EverestAir can sense airborne articles and increase or decrease the fan speed to best clear the air. We love that it can detect PM 1.0, PM 2.5, and PM 10 which includes everything from fine dust to pet dander, dust, pollen, ash, and airborne allergens. In our tests, the Levoit EverestAir cleaned the air about 5 times per hour on the highest setting in a single room with the door closed. We suggest leaving it in a central space and opening your doors as it has the capability of purifying 354 cubic feet per minute.

Dreame AirPursue PM20

I’ve been using the Dreame AirPursue PM20 for nearly nine months, and though it may be bulky, it has alleviated my allergies. The Dreame AirPursue PM20 detects and purifies the air of PM1, PM2.5, PM10, HCHO, and TVOC, which you can monitor in real time in the app. Dreame notes that the air purifier can clean 1,833 square feet in 15 minutes. I put this to the test and discovered that the air purifier cleaned the air of toxic contaminants from hair spray in about 11 minutes.

The Dreame AirPursue PM 20 is outfitted with a HEPA 13 grade filter which removes indoor pollen, dust mites, bacteria, haze, viruses, and other materials efficiently. A carbon filter maximizes the filter quality by removing kitchen fumes, pet odor, TVOC, formaldehyde, and other harmful gases. If all that wasn’t enough, the Dreame AirPursue PM20 has smart features like AI Purify that automatically switches on the purifier when it recognizes any pollutants increasing. Plus, with AI follow, the purifier tracks your movements around the room and adjusts the air flow to clean the air around you. For an allergy sufferer, this can make a tremendous difference. The $639.99 / £499 price tag is high, but considering all the smart features, its cooling and heating capabilities, and pet and comfort modes, it’s a worthy allergen-reducing tool to invest in.

Dyson has just launched a new personal fan that you can place on your desk while you work, carry on public transport, or even wear around your neck. The Dyson HushJet Mini Cool Fan has a compact bladeless design and five airflow modes — plus a boost button when you need relief from the heat fast.

It can run for up to six hours on a single charge, and weighs 7oz/212g. It comes supplied with a Neck Dock for moments when you want to stay cool hands-free, as well as a charging stand, travel pouch, and USB-C charging cable. Other accessories available to buy separately include a Universal Mount for securing the fan to objects like pushchairs or gym equipment, and a Clip Grip for fastening it on bag straps or jackets (particularly helpful for commuting).

The HushJet Mini Cool Fan comes in three colorways: Ink/Cobalt, Carnelian/Sky, and Stone/Blush, so you can pick one that will suit your wardrobe.

The new fan looks striking, but it should sound discreet thanks to the HushJet nozzle, which lowers frequencies so you're not distracted by annoying high-pitched whirring and whining.

This looks set to be a particularly cool summer, because the Dyson HushJet Mini Cool Fan has arrived just a few weeks after the Shark ChillPill — another compact fan with a rechargable battery that's designed to be used indoors or on the move, but which also features a misting attachment that sprays you with quick-drying water vapor, plus a cooling plate that you can apply to pulse points for fast relief on hot days.

The HushJet Mini Cool Fan lacks these two extra features, but it's both lighter and more affordable. The Shark ChillPill is $149.99 / £129.99, whereas the Dyson HushJet Mini Cool Fan is $99 / £99.99.

The HushJet Mini Cool Fan will be available to buy later this month, direct from Dyson's website and from Dyson demo stores in the UK and US. Aussies will have to wait a little to find out local pricing and availability, although it's confirmed to be coming Down Under — you can head to the Dyson Australia website to be notified as soon as it drops.

I'll be putting it to the test soon to see how it compares to the ChillPill in terms of cooling power, noise, and convenience, and I'll bring you a full review once I've put it through its paces.

It was all thanks to a new series of fans called the TurboCool, six examples of which blasted me with a powerful wave of air, all while enveloping me in a dreamily cooling haze of fine mist. I could have stood there all morning.

Misting fans are having a bit of a moment right now, thanks perhaps to the popularity of the Shark FlexBreeze (which sits at the top of my best fan guide). But in many ways, Dreo's version is better – especially if misting is your priority.

There are three models in the range. My favorite is the 516S – a cheaper, more compact version designed for indoor use. However, if you want more intense indoor cooling, there's a tower version (the 765S). And you can even take the party outside with the 765S – a misting tower fan for outdoors.

All three have integrated water tanks and misting built-in as standard – although it can of course be switched off. One big USP here is how the misting is handled on the indoor options.

The outdoor version can emit large mist particles for maximum cooling impact. But indoors, there are soft furnishings to worry about.

To remove the possibility of damp sofas and carpets, Dreo has meticulously fine-tuned the mechanics here. The indoor TurboFans emit an 'ultrasonic' mist that's so fine it'll evaporate almost the instant it leaves the fan.

I can attest to its effectiveness: I stood for several minutes with my face right up to the fan display, with all models on full blast. My hair wasn't the slightest bit damp when the Dreo rep gently suggested it was time to move on.

Although the particles disappear quickly, the cooling effect is still significant – the tower version can cool a room by up to 10F (~15.5C) while the mini version can drop temperatures by up to 5F (~2.5C).

(For clarity: a regular fan doesn't actually lower the temperature in a room, but a misting fan can, so this is the type to go for if you want some genuine chilling power.)

I was also pleased to see there's plenty of control here. On the indoor tower fan you can choose from 12 speed options and 4 mist levels, and on the compact version there are 6 fan speeds and three mist levels. There's also smart control via Dreo's companion app.

The Dreo TurboCool is due to launch in the US and UK in April 2026. It'll cost $99 for the smaller indoor fan (516S), $179.99 for the outdoor tower fan (711AS), and $199.99 for the indoor tower fan (765S) – UK pricing is expected to be roughly equivalent, so around £75 for the 516S, £135 for the 711AS and £150 for the 765S.

The Dyson Hot+Cool HF1 is a sleek and smart fan heater with the bladeless and aesthetically pleasing design we expect to see from the brand.

With a premium list price of £399.99, the Dyson Hot+Cool HF1 can be found at Dyson and a few other retailers. Sadly, it’s only available in the UK at the time of publishing, but I’ll provide an update if it ever makes its way off the island.

The HF1 offers ten fan speeds, three oscillation options of up to 70 degrees, a heater that can kick out up to 90ºF / 32ºC, and, most excitingly, some desirable smart features.

During testing, I found the HF1 to be very efficient in both Cool and Hot modes. The lowest setting delivered a delicately cooling breeze to me as I sat on my couch six feet away.

There are plenty of ways to control the HF1, with a few onboard controls, a remote, and the MyDyson app, which gave me access to the whole suite of settings and features.

I could perform most actions with the remote, but its communication with the HF1 was a bit patchy at times. The MyDyson app made controlling the HF1 delightfully easy and offered me a wider range of timer options, as well as scheduling, historical ambient temperature data, and, pleasingly, the option to turn on heat mode remotely so I could return to a warm living room.

The fan’s volume was perfectly acceptable and on par with most of the similar fans I’ve tested. Sleeping with the HF1 a few feet from the bed was a smooth ride, for the most part. However, when it came to using Hot mode, I found that it would go through a period of being particularly noisy for a few moments as it got up to temperature, which it would do whenever the ambient temperature dropped below the target I’d set.

This wasn’t so bad in the daytime, but as one of its selling points is that you can use it in your bedroom overnight to keep the temperature at a desirable level, it’s worth bearing in mind if you’re a light sleeper.

If you have children or inquisitive pets, it’s also worth noting that the metallic edging at the front of the air purifier can get very hot very quickly, and that the child lock only applies to the onboard controls. So if you have a rampaging toddler or a clumsy cat, this could potentially prove inconvenient.

Overall, though, the Hot+Cool HF1 is a satisfyingly efficient fan heater. While it has a high price tag, it’s worth it for the performance and convenience, especially with those clever smart features.

Dyson Hot+Cool HF1 review: price & availability

• List price: £399.99
• Launch date: October 2025 (UK)
• Availability: UK only at time of publishing

The HF1 is a premium option packed with some fantastic features, but as is often the case with Dyson, it has a premium price tag to match, costing £399.99.

The Dyson Hot+Cool HF1 is currently only available in the UK, and can be purchased from Dyson, Currys, and a few other retailers.

There’s a price difference of £150 between the HF1 and the Dyson Cool CF1, which is actually pretty reasonable considering the addition of Hot mode and the fantastic smart features.

Overall, with its good performance and a number of convenient features, the Dyson Hot+Cool HF1 won't disappoint if you have the money to spare. However, it’s worth considering the drawbacks I’ve covered in my review to ensure they won’t pose an inconvenience before you stretch your budget.

Dyson Hot+Cool HF1 review: specs

Dyson Hot+Cool HF1 review: design and features

• Small and lightweight design, which can be tilted
• The HF1 has 10 fan speeds and outputs temperatures up to 90ºF / 32ºC
• MyDyson app offers extra settings and features, including a pre-heat function

Setting up the Dyson Hot+Cool HF1 was a quick and simple process of attaching the plastic base plate and connecting the HF1 to the MyDyson app.

The Dyson Hot+Cool HF1 is conveniently sized, with a max diameter of 8 inches / 20.4cm once the base is attached; however, at 23 inches / 58.5cm, it might feel a smidge tall for desktop use.

Though it feels a little wrong, as I’m used to using larger-scale formats like the Dyson HP10, it worked perfectly well on the floor. Whether you place it on a tabletop or the floor, the vertical angle of the airflow can be adjusted slightly by shifting the fan’s body backwards or forward to tilt it.

Predictably, the Dyson Hot+Cool HF1 fan features a bladeless design, making it easier to clean and a safer option to bladed fans for those who happen to have curious offspring or pets.

In addition to its 10 fan speeds, the HF1 can oscillate 15, 40, or 70 degrees. Both of these functions can be adjusted via the onboard controls, with a power button/dial combo that can be turned to increase or decrease the fan speed, a button to cycle through oscillation angles, and another button that enables Hot mode.

Hot mode offers a temperature range of up to 90ºF / 32ºC, and the combination of the ceramic heater plates and Air Multiplier technology can apparently increase whole-room temperature by one degree in as little as one hundred seconds.

Like the Dyson Cool CF1, the Hot+Cool HF1 also comes with the standard Dyson-style magnetic remote control, which can be stored on top of the loop amplifier. It features power, oscillation, fan speed, and temperature control buttons, as well as ones to enable sleep mode, set the timer, and engage the child lock.

One advantage the HF1 has over the Cool CF1 is its app integration, which gives access to an advanced range of settings, historical temperature readings, outdoor air quality data, and easy remote control, whether you’re out and about or sitting on the couch. Plus, there’s the option to connect the HF1 to your smart home system, so it can be controlled without lifting a finger.

Perhaps the most exciting aspect of the HF1's smart capabilities is the ability to preheat a room to your desired temperature, ready for when you return home.

Dyson Hot+Cool HF1 review: performance

• Good performance for its size in both Cool and Hot modes
• Very easy to control, thanks to the MyDyson app
• Quiet overall, but noisy while getting up to temperature in Hot mode

The Dyson Hot+Cool HF1 was simple and straightforward to use, especially when using the app. I often used the remote, too, but there was a bit of a lag whenever I made an adjustment, and the HF1 didn’t register the command at all at times.

When testing from my couch, which was around 6ft / 1.8m away from where I’d placed the HF1, the breeze from speed one wasn’t really detectable when the fan was static, which isn’t really a surprise considering its size. However, when I set it to oscillate at 40 degrees, it was enough to give a gentle and surprisingly effective cooling breeze.

As you’d imagine, the breeze felt a little more prominent with each setting increase, until speed five, when the airflow felt noticeably amplified, and I could hear a quiet windrush past my ears.

The airflow was satisfyingly strong at top speed 10, though it was a little noisy at 45dB from 6 feet away, which was loud enough for me to need to turn the volume up on my TV.

When I measured the sound output of the HF1 in Cool mode from the usual 2ft distance, I found that it produced a similar volume to the Dyson Cool CF1 and the Levoit Circulair. However, its readings of 29dB at speed one, 36dB at speed five, and 50dB at speed ten, conveyed that the HF1 is a whole 10dB louder at its top speed than the Meacofan Sefte 8in.

These aren’t bad volumes, though, with the HF1 operating as quietly as a whisper, to as loud as moderate rainfall when in Cool mode. Some may find the oscillation sound mildly distracting because, as I discovered when reviewing the Cool CF1, it’s reminiscent of the droning of a document scanner. The oscillation itself is only around 28dB, however, and the whirring was subtle enough that I could fall asleep to it.

As it’s getting mighty chilly in the UK as I write this, I’ve been very grateful to have the opportunity to test out Hot mode.

I could easily find out the current room temperature by looking at the fan’s display or checking the app, and the temperature was very straightforward to adjust a degree at a time using the buttons or the slider in the app.

It’s important to note that, while Dyson states that the HF1 is safe for family and pets as there are no exposed heater elements, it would appear this doesn’t eliminate the chance of scalding, as I found that the metallic edging around the air outlets became too hot to touch within just a couple of minutes in Hot mode at 73ºF / 23ºC.

Hot mode starts off noticeably louder than Cool mode. The HF1 is fairly quiet for the first few moments, then quickly ramps up before settling down to a consistent volume. For example, when using Hot mode at fan speed five, the volume quickly rose to 42dB, then settled down to 37dB.

True to Dyson’s claim, the HF1 did increase the temperature by a degree in less than two minutes, though I’m not sure how accurate the temperature reading is when it comes to the ambient temperature across a large room.

As the ambient temperature is monitored for Hot mode, I would have liked to see Dyson use it for an auto function for Cool mode so that it could adjust the fan speed based on how hot the room is, as I loved this feature in the Meacofan Sefte 8in.

Another change I’d love to see is the extension of the child lock beyond the onboard controls, so the remote cannot be used either. Having access to the app should mean this wouldn't cause inconvenience for adults, but even if not, Dyson could take a leaf out of other brands’ books and assign a combination of buttons to unlock the remote.

When I set the HF1 to sleep mode at bedtime, it turned off the display and reduced the fan speed to four, which has a volume of 29dB, though I could still adjust the speed if required.

Due to the weather in the UK right now, I mostly used the hot mode overnight. Aware that a key feature of the HF1 is that it will start up whenever the temperature drops, and having witnessed how noisy Hot mode can get, I set it to fan speed one to minimize disturbances.

I can recall it waking me up at one point in the early hours of the morning, but it wasn’t loud enough to shock me awake, and I fell back to sleep once it had settled down. It should hopefully be bearable enough for most people, but I definitely wouldn’t recommend it if you’re a particularly light sleeper.

While the hot mode might be good for speedy heating, it would be great if the sleep mode could increase the heat gradually, so there wouldn't be such a sudden volume increase. It’s also worth noting that the display doesn’t appear to turn off when in sleep mode if you’re using the heat function.

Overall, though, I quite like the Dyson Hot+Cool HF1. I appreciate how no fan speed felt redundant from six feet away, and that it was light enough to relocate without much effort. So, while the HF1 may not be the right fan heater for you if you’re a light sleeper who intends to use Hot mode overnight, for everyone else its smart features, effortless remote control, energy-saving Hot mode, and satisfying airflow make it a great choice.

I unboxed the Dyson Hot+Cool HF1, attached its base, and set it up on the MyDyson app. I tested it out on different surface heights, on the floor, and next to my bed. I did most of my testing with the HF1 where I usually place my table fans, about six feet away from my couch and near my bed at nighttime.

I adjusted the settings using the onboard controls, the remote control, and the MyDyson app. In the app, I went through the setup process before exploring the different settings and sections.

I used all the fan speeds in Hot and Cool mode, and measured the sound output. I used it in Hot mode on my bedroom windowsill when I went to bed at night, using the timer so that I didn’t get too toasty after I fell asleep.

On a recent visit to Dyson's campus in Malmesbury in the west of England, I got the chance to pick the brains of Sophie Harold, an acoustics and vibration engineer at Dyson. Here's what I learned…

The terms that Dyson employees use to refer to the brand's bladeless fans are 'Loops', 'Amps' (short for 'Air amplifiers'), or, occasionally, 'Race tracks'. This is the traditional Dyson aircare product format.

"They've got a gap in the middle [and] slots on the side, and they've got fast air out of the plastic outer loop," says Sophie. This, she explains, causes something called 'entrainment', where the loop pulls in air from elsewhere in the room, to create an effect the brand calls 'air multiplication'.

"It means that… say you put the new CF1 on the desk, the air that you feel at your face is even more air than the motor or the compressor itself is generating, because it's dragging in air from the room as well," Sophie continues.

Compact cones

The Loop is just one of the formats Dyson uses to wrangle air. It also makes many of the best air purifiers on the market. In fact, a number of its models act as fan-purifier combos, because the processes required are so similar.

Some of Dyson's more recent purifiers use a 'Cone' rather than a Loop. This looks a bit like a bowl, and appears on the likes of the Dyson Big+Quiet. Because there's no need for an empty space in the middle, these kinds of products can be a bit more compact in shape, and shorter. Or, they can cram an awful lot of power without being absolutely massive – as is the case with the Big+Quiet.

"They use Coanda, so that's causing [air]flow to adhere to a surface. That's the same tech that the Airwrap barrels use to cause the hair to swirl around and get that nice curl shape," says Sophie.

"What it does here is it uses the surface to direct the air so where you would have to oscillate a Loop fan, with a Cone, you can just vary the strength of the jet at the top and the bottom, and it moves the flow up and down. That's the primary thing that that shape can do."

Starry eyed

The newest air purifier in the Dyson lineup – the HushJet Purifier Compact – doesn't use a Loop or a Cone, it uses a 'Star' nozzle.

The new Star nozzle is interesting because it causes entrainment without having to have the big gap in the center (as Loops do), so it can have a more compact shape than an amp fan. The HushJet is Dyson's first compact air purifier.

"It drags air from the rest of the room with it, making a really powerful jet, and it does that by having that star shape," says Sophie. "By having the kind of bending edges, it's still encouraging air from the surrounding region to join in with the fast jet."

"It also means the air is quite fast," she continues. "Similar to the Air amps, which have very narrow slots, this has a contraction into the star shape, smaller than the motor is, which means the air can go really quickly, mix well and purify the room." I've heard it likened to a jet engine, or perhaps more relatably, the Concentrator nozzle on a hair dryer.

Fans and filters

As I said earlier, many of Dyson's fans can also function as air purifiers. However, not all models are pulling double duty. I asked Sophie how the designers' approach differs depending on what the appliance needs to do.

"[For a] purifier, you might focus on mixing the air in the room, rather than directing the air flow at your face. It's much more important to get good filters on the product," she explains.

"Whereas things like the CF1 [fan], they don't have filters on, and that's because it means you can run the motor more efficiently, get lower running costs, and just get the cool flow on your face, rather than focusing on really getting all the air through and purified."

Dyson is known for making some of the best air purifiers on the market, but they're not especially compact. In fact, some of them are downright massive (looking at you, Dyson Big+Quiet). So when I heard the brand was launching its first-ever desktop machine, I was intrigued.

For the HushJet Purifier Compact, Dyson had to rethink its air purifier design. The models in the current lineup either use loops/amps (as seen on the Purifier Hot+Cool Formaldehyde HP09) or cones (like on the aforementioned Big+Quiet), which are effective but take up a lot of space. In contrast, the new addition has a space-saving, star-shaped nozzle that operates in a completely different way.

The design is inspired by a jet engine – or a hair dryer's concentrator nozzle, if you're looking for a more commonplace analogy. The motor is bigger than the star nozzle, so air is compressed as it pushes through. So while it uses the same principle of entrainment (i.e., dragging air in from the rest of the room, making a more powerful jet) as other Dyson purifiers, it does so in a more compact format.

"The new star nozzle is exciting because it still does entrainment without having that gap in the middle," Dyson engineer Sophie Harold told me when I visited the Dyson campus to take a look at the brand's new launches. "By having the bending edges, it's still encouraging air from the surrounding region to join in with the fast jet. It also means you can have a compact shape when you want something like a desk purifier, without having an amp that might get in the way of your monitor."

All of that sounds very impressive, but in reality, when the HushJet was unveiled, I was a little disappointed. While it's smaller overall than Dyson's other air purifiers, it's not what I'd call compact, and it's certainly too big to sit naturally on a desk. If you're putting it on the floor, really, it's the footprint that's relevant, and at 9.1in / 23cm in diameter, it's not wildly different from other Dyson purifiers. So long as you're not expecting something ultra-compact, however, there are more plus points to this new machine.

Controlling the chaos

The new star-shaped nozzle has benefits in terms of acoustics – meaning that despite being inspired by planes, it's actually extremely quiet in operation. I listened to it on its lowest setting in a Dyson labs anechoic chamber (i.e., one designed to stop any echoes – it was so quiet I could hear my own heartbeat), and I could barely hear it.

"We often look at something called turbulence of flow, and that's to do with how disordered or chaotic the [air]flow is," explained Sophie. "Imagine people waiting to get on a train and trying to design a shape of a door, which means that they can all get out calmly and peacefully, rather than all banging into each other and causing chaos. So what the star does is, it reduces that chaos. It minimizes the amount of turbulence coming out of the jet, which means, in turn, that the flow itself is quieter, and it's what's enabled us to have that really quiet speed setting."

The final big upgrade on the HushJet is that it uses an electrostatic HEPA filter, which is more energy efficient than a regular HEPA filter and lasts much longer. In fact, Dyson says this filter can last up to five years before needing replacing – significantly lessening the ongoing costs of running this purifier. The system is fully sealed, so anything that's sucked up stays inside.

For those of you who are sold on the new design, I have a bit of bad news: you have a little while to wait. The Dyson HushJet Purifier Compact air purifier isn't scheduled to go on sale until early 2026 (that's the date for the UK – I'm awaiting confirmation of when it's expected to launch in the US and Australia). Pricing information is also TBC.

Do you have money to spend and want to save on space? If so, the multi-talented Dyson Purifier Hot+Cool Gen1 HP10 purifying fan heater is a compact solution for combating chilly days or hot nights, while helping to purify airborne nasties, too.

The Dyson Purifier Hot+Cool Gen1 HP10 purifying fan heater is available at multiple retailers in the US, UK, and Australia at a list price of $529.99 / £549.99 / AU$899, though I’ve spied the occasional discount in the US from the likes of Dyson and Amazon, who are both offering the HP10 for just under $400 at the time of writing.

The price is on the steep side, considering you can get a far smarter air purifier like the Dyson Purifier Cool Formaldehyde TP09 for a similar price or sometimes less. You can also get the full-sized tower fan version, the Dyson Purifier Cool Gen1 TP10, for a whole $100 / £100 / AU$100 cheaper. Neither has a heat function, admittedly, but if I had the budget, I’d be looking to buy the TP09 when it’s on offer, and buy a separate heater.

At just 30.2 inches / 77cm tall, the HP10 is a stumpier, yet slightly chunkier and heavier, version of the TP10. It’s too chonky to sit on a tabletop, and has a relatively short loop amplifier, but it makes up for this with its ability to be tilted, so it’ll cool more than just your knees – happy days.

The HP10 has a lot of skills to its name, with 10 fan speeds, a multi-temperature heating mode, and oscillation of up to 350 degrees. Thanks to its low noise level, I found it easy to sleep with the HP10 next to my bed, and found the tilting element useful for perfecting the airflow angle.

Auto mode performed well during testing, though it is basic, as it only has the ability to detect and react to PM2.5 and PM10 contaminants. It’s important to note that – as is the case with many other air purifiers on the market rocking a HEPA H13 filter – just because a device may not have the capacity to detect and react to other contaminants like VOCs, it doesn’t mean that it isn’t helping to filter them out.

Overall, I really like the multi-functional format of the Dyson Purifier Hot+Cool Gen1 HP10 purifying fan heater, and was impressed with its performance, so if you’ve got the budget and don’t want a particularly smart air purifier, you won’t be disappointed with the HP10. But personally, if I had the space (and the budget), I’d opt for the smarter TP09 and buy a separate little fan heater for colder days. If you’d like to take a look at other options, I suggest checking out our pick of the best air purifiers and the best fans for options we highly recommend.

Dyson Purifier Hot+Cool Gen1 HP10 review: price & availability

• List price: $529.99 / £549.99 / AU$899
• Available now in the US, UK, and Australia

The Dyson Purifier Hot+Cool Gen1 HP10 purifying fan heater is available to purchase at Dyson, Amazon, and multiple other third-party retailers, and has a list price of $529.99 / £549.99 / AU$899.

This isn’t a terrible price if you’ve got your heart set on a Dyson appliance and desperately want all three functions in one small package. But considering you could get the impressively performing Dyson Purifier Cool Formaldehyde TP09 purifying tower fan for a similar cost, or even less, or spend $100 / £100 / AU$100 less on the taller Dyson Purifier Cool Gen1 TP10 purifying fan and just buy a separate heater, I’d recommend thinking over your priorities before buying.

That being said, the Dyson Purifier Hot+Cool Gen1 HP10 purifying fan heater can occasionally be found for less. For example, it’s “Dyson Week” on the Dyson US website at the time of writing, which has knocked the price down to a far more acceptable $399.99, and Amazon US is offering the HP10 for $399 too, so it’s worth checking if any discounts are available.

The Hot+Cool Gen1 HP10 uses the same filter as many of Dyson’s other purifier models: the 360 Combi Glass HEPA + Carbon air purifier, which has a list price of $79.99 / £75 / AU$99. Dyson recommends the filter be changed every twelve months, based on usage of twelve hours a day, so it’s important to factor this in as an ongoing cost. Most air purifiers need regular filter changes, though some, like the Shark NeverChange or the Blueair Blue Pure 411i Max / Blue Max 3250i, employ helpful washable pre-filters in an attempt to extend the lifespan of their single-use filters.

Overall, if you’re a Dyson fan with the right budget who wants three appliances in one conveniently compact package, you’ll be happy enough with the Dyson Purifier Hot+Cool Gen1 HP10 purifying fan heater. If you’d rather sacrifice a little more floor space over creating a noticeable void in your bank account, however, you may want to consider individual appliances instead.

Dyson Purifier Hot+Cool Gen1 HP10 review: specs

Dyson Purifier Hot+Cool Gen1 HP10 review: design and features

• Three functions in one package: cooling, heating, and purifying
• Short in stature, but can be tilted for better airflow position
• No smart features

With its bladeless loop amplifier and metallic details, the Hot+Cool Gen1 HP10 purifying fan heater has the classic Dyson aesthetic we know and love. The white and nickel color of the sample I tested is available in the US, UK, and Australia, but Dyson also offers a white and gold version on their UK site, and a white and silver model in the US.

At first glance, I’d say it’s a little on the short side for a tower fan, and it’s too chunky and heavy to easily fit on a tabletop, but its ability to tilt forward and backward means that the airflow can be easily directed. I think I may actually prefer this format to the taller tower fan loop amplifiers, as the airflow feels a bit more concentrated.

Weighing 11.7lb / 5.3kg, the HP10 is surprisingly heavy for its size, and I can only assume it must be the heating element that makes it heavier than its taller siblings.

Other than the power button, there are no controls on the HP10 itself. All of the controls are accessible via the slightly curved remote, which sits magnetically on top of the loop amplifier when not in use. It houses buttons to increase and decrease the fan speed or heat level, a button to switch back to cool mode, an info button, and buttons to toggle oscillation, auto mode, or Night mode.

By pressing the info button, I could cycle through the different detail screens on the front of the purifying unit. This includes graphs showing air quality changes either recently or over a 24-hour period, PM2.5 and PM10 readings, filter status, and the ambient temperature.

At this price point, it’s a little disappointing that the HP10 doesn’t have any smart features. This means that historical data is limited to the little 24-hour on-screen graph, and control is limited to the remote.

When Auto mode is enabled, the HP10 will react accordingly to rising or falling levels of PM2.5 or PM10 contamination. There’s a timer function that can be used if you don’t want the HP10 running all day if you’re out of the house, but it’s tied in with Night mode, so it can’t be used without the display being dimmed.

The HP10 comes with a 360 Combi Glass HEPA + Carbon air purifier filter, which is an H13-grade HEPA filter and is understood to capture 99.95% of particles as small as 0.2 microns. Though the HP10 only automatically reacts when it detects PM2.5 or PM10 contaminants, it’s worth noting that its HEPA and carbon filter are still capable of capturing other airborne nasties, like VOCs.

Dyson Purifier Hot+Cool Gen1 HP10 review: performance

• Easy to operate
• Tilt function proved useful
• Reacted promptly to PM2.5 and PM10 contaminants

It was really easy to use the Dyson Purifier Hot+Cool Gen1 HP10; all the buttons on the remote were self-explanatory, and it was pleasingly responsive and had a good range.

The Dyson Purifier Hot+Cool Gen1 HP10 reacted quickly when I sprayed dry shampoo toward it from around two feet away. It took just a couple of seconds to detect the contamination, instantly spiking the PM2.5 and PM10 readings, turning them purple to indicate very bad air quality. The readings were lowered to around 30 micrograms in around a minute, which is considered good on Dyson’s air quality scale.

The strength of the airflow was fine for its size, but noticeably less than the larger tower fan models. I could feel a cooling breeze from two feet away on fan speed one, four feet on speed five, and 10 feet on top speed ten.

I felt the benefit from the heat mode pretty quickly. The screen showed a little thermometer with the current room temperature noted, and I could raise or lower the temperature a degree at a time using the plus and minus buttons on the remote.

Night mode worked as expected, with the fan speed dropping to four and the display dimming, either permanently or on a timer of up to eight hours. I liked that I could still increase the fan speed in Night mode, as that means no choosing between light pollution or overheating on a hot night. Being able to tilt the HP10 was also really helpful when setting the airflow to the right angle at bedtime.

The HP10 was lovely and quiet, with a volume of just 30dB when running on fan speed one, 41dB on speed five, and 53dB on speed ten when I tested it. These readings were very similar to those recorded from the TP09 and TP10, with the HP10 operating as quietly as a soft whisper on its lowest setting, and about as loud as moderate rainfall at its highest.

How I tested the Dyson Purifier Hot+Cool Gen1 HP10

• I used the Dyson HP10 purifying fan heater in my living room and bedroom
• I observed its detection and purification skills
• I evaluated the strength of the airflow and the sound levels

I used the Dyson Purifier Hot+Cool Gen1 HP10 purifying fan heater in our photo studio, my living room, and my bedroom for two weeks. I evaluated how easy it was to operate, along with the build quality and aesthetics, and explored the available functions and features.

I tested the strength of the airflow by determining at what distance I could still feel a cooling breeze. I also observed the HP10 purifying fan heater’s detection and purification skills during standardized testing, which included spraying dry shampoo towards it from around two feet away to test how quickly it would react and clear the contamination, and I also used it passively in my bedroom and my living room.

I used a decibel meter app on my iPhone to record the noise levels, taking readings from around two feet away and ensuring the fan wasn’t blowing directly into the microphone.

I checked the timer worked as expected, and tested out the sleep mode to see whether the HP10 was quiet enough for me to be able to sleep well with it running overnight.

The Dyson Purifier Cool Formaldehyde TP09 is a tower fan and air purifier combo with smart capabilities, which allows for easy control and air data reviewing via the MyDyson companion app.

With a list price of $749.99 / £549.99 / AU$999.99, the white and gold Dyson Purifier Cool Formaldehyde TP09 purifying fan is well-priced in the UK and Australia, but curiously costs much more for the nickel and gold colorway at Dyson US. Fortunately, I’ve spotted the white and gold model at a discounted rate from third-party retailers, with Walmart offering it for just $519 at the time of writing.

Replacement filters are on the pricey side at a list price of $79.99 / £75 / AU$99, and Dyson recommends changing them every 12 months, so it’s important to factor this cost into your budget.

I really like the aesthetics of the UK model I tested, the white and gold colorway is a little more exciting to look at than the standard white and nickel we see on other Dyson purifying fans – though I must say, I consider the color of the shroud to be more copper than gold.

There are 10 fan speeds on offer, plus an auto mode that rouses the TP09 into action whenever it detects contaminants. And it's able to detect these from an impressively wide range of sources, including PM2.5 and PM10, VOCs, formaldehyde, and nitrogen dioxide.

In fan mode, it offers a decent flow of air, and while it's not as powerful as the best fans I've tested, it's still strong enough to be useful on a hot day. For when you don't need cooling, Dyson has added a Diffused mode, which diverts the airflow out of the back of the loop amplifier. This means you don’t have to worry about it blasting cold air toward you as it tackles contaminants in the winter months, and is an option you won't find on cheaper Dyson purifying fans.

The MyDyson companion app proved insightful and responsive when communicating air quality changes and when I was using it to control the TP09. It offered insight into the air quality readings and also provided access to some great additional controls, such as selecting the point to begin oscillating from, saving me from needing to adjust the position of the TP09 manually.

The TP09 reacted promptly to contaminants both in testing and day-to-day use. It was quick to notice whenever I sprayed myself with perfume on the other side of the room, and automatically increased the airflow to tackle the detected VOCs. Despite this though, it didn’t have any noticeable effect on the fragrance in the air.

The TP09 delivered an impressive performance overall. It proved easy to operate, the controls were responsive, and it was quick to react whenever contaminants were introduced. It didn’t appear to tackle odors well, but I’m yet to test an air purifier that performs particularly proficiently in this area.

Considering the range of contaminants the TP09 is capable of detecting and reacting to, plus the responsive controls, air quality breakdown and air quality history available on the MyDyson app, you get plenty of bang for your buck with the Dyson Purifier Cool Formaldehyde TP09. I highly recommend shopping around for the best price if you’re in the US, though.

In fact, I’m such a fan of the purifying abilities of the TP09 that I could easily see it sneaking its way into our list of the best air purifiers.

Dyson Purifier Cool Formaldehyde TP09 review: price & availability

• List price: $749.99 / £549.99 / AU$999.99
• Available now in the US, UK, and Australia

Available to buy from the Dyson website and other third-party retailers in the US, UK, and Australia, the Dyson Purifier Cool Formaldehyde TP09 purifying fan has a list price of $749.99 / £549.99 / AU$999.99. This is an attractive price in the UK and Australia, but a little high in the US.

If you’re in the US, then I’d highly recommend shopping around. While the nickel and gold model is pricey on the Dyson website, at the time of writing, I’ve spotted the white and gold Dyson Purifier Cool Formaldehyde TP09 for much more reasonable prices at Amazon, Best Buy, and Walmart, with the latter offering the TP09 for just $519.

When shopping for an air purifier, it’s always a good idea to check out the prices of replacement filters, so you don’t get a nasty shock when it comes time to switch them out. Dyson recommends changing the HEPA H13 filter every twelve months, based on it running twelve hours a day. As a replacement filter for the TP09 has a list price of $79.99 / £75 / AU$99, it’s worth factoring this cost into your budget.

If you’ve got your heart set on a Dyson purifying fan, but don’t have the budget for this model, I’d recommend taking a look at the Dyson Purifier Cool Gen1 TP10 Purifying Fan instead. However, if you can afford the extra spend, it’s worth it for the benefits of the air quality data, app control, and the diffused mode.

Dyson Purifier Cool Formaldehyde TP09 review: design and features

• Attractive design and colorway
• Diffused mode for purifying when you don’t need cooling
• Capable of detecting and reacting to a wide range of contaminants

With its large loop amplifier, it doesn’t take a second look to know that the TP09 purifying fan is a Dyson. The materials look and feel good quality, and the overall build feels satisfyingly sturdy. I’m also a big fan of the white and gold colorway, though I’d say it’s really more of a copper tone than gold, personally.

A clever combo of a bladeless tower fan and an air purifier, the TP09 offers a solution to a niggle I had with the cheaper Dyson Purifier Cool Gen1 TP10 model, which was that I couldn’t make use of the higher purifier settings without being blasted with air from the fan. This solution comes in the form of Diffused mode, which diverts the airflow out of the back of the loop amplifier, so I no longer feel like I’m making it face the corner in shame when I want to make the most of its purifying capabilities.

The setup process was fairly easy, though at a weight of 10.7 lb / 4.85kg and with no carry handles, I’d definitely recommend pulling the side of the box down before sliding the TP09 out, rather than trying to lift it out as stated in the online manual. Curiously, Dyson included a leaflet that’s only printed on one side to communicate that they’ve moved the setup process online to save paper.

I’d also really like to see brands like Dyson doing more product and transit testing to see whether they can cut back on their use of plastic wrap, as individually wrapping both halves of the air filter, the entire tower fan and the outer cardboard box in plastic feels somewhat excessive.

The TP09 uses the same H13 HEPA filter that’s used in most of their newer models, including the cheaper ones, but adds a permanent catalytic filter, which continuously traps and converts formaldehyde (HCHO) into water and CO2. Another big difference between the TP09 and cheaper models is its ability to detect and react to more than just PM2.5 and PM10 – which are particles up to ten microns in size, including smoke, bacteria, and dust – as it can also detect and react to volatile organic compounds (VOCs) and nitrogen dioxide, too.

The large and well-lit LCD screen on the front of the purifying unit made it easy to keep an eye on the overall air quality or the level of individual pollutants. I could cycle through the different readings using the satisfyingly color-matched remote, which also allowed me to enable diffused mode, auto mode, and night mode, as well as adjust oscillation angle, and airflow speed.

Dyson Purifier Cool Formaldehyde TP09 review: app

• Shows a week's worth of air quality data in 15-minute intervals
• App remote control is responsive
• Provides extra options for timer and oscillation

It’s quick and easy to get an insight into the air quality in the room on the MyDyson app, thanks to the helpful graph that shows the overall air quality in fifteen-minute intervals over the last week. It specifies the most dominant pollutant at the time, which is useful for working out exactly what’s causing any drops in air quality. There are also graphs available to show the level of each pollutant, as well as for ambient temperature and humidity.

The app offers lots of detail on what various terms mean; for example, it lists the different air quality ratings, explains what each one means, what action should be taken, and gives details on each contaminant type it detects. It also provides the ranges of the pollutant readings, such as a reading of 0-35 micrograms per cubic meter being considered Good, and 151-250 being Extremely Poor.

One thing that anyone purchasing the TP09 (or any of Dyson’s air purifiers, really) needs to do in the first instance is to make sure that continuous monitoring is turned on, as it is switched off by default. Without doing this, your air purifier won’t consistently collect data. It’s simple enough to enable, either in the machine settings within the MyDyson app, or by holding the Auto button on the remote for roughly five seconds, until the LCD screen on the device confirms the setting has changed.

Along with providing plenty of data on the air quality inside my home, I was also able to keep up to date with what was going on outside. After entering my location into the MyDyson app, I had access to a simple-to-read dashboard detailing the external temperature, humidity, grass pollen level, plus PM2.5, PM10, and NO2 readings.

The level of controls on offer was fantastic. There are basic settings for power, auto mode, oscillation, and fan speed available on the main TP09 dashboard, but further controls became available after pressing the remote icon. This gave me access to all of the controls I had on the remote, but with far more flexibility. For instance, there's a timer that’s separate from Night mode and offers a wider duration variety. There's also an option to choose which position the TP09 begins its oscillation from – this is a fabulous feature to have, as it saves having to go and manhandle the fan if it’s not quite in the right position.

Dyson Purifier Cool Formaldehyde TP09 review: performance

• Easy and straightforward to operate
• Detects and reacts to a wide range of contaminants
• Fast detection and reaction speeds

The Dyson Purifier Cool Formaldehyde TP09 purifying fan was satisfyingly easy to operate throughout my weeks of testing it. Controlling it was simple and stress-free, as both the remote control and the controls on the app were straightforward and very responsive.

I didn’t have much luck when setting up voice control, but I can’t say if this is a fault with the appliance or the third-party apps I was using. I could voice record Siri shortcuts, and they would appear in the Shortcuts app on my iPhone, but my voice commands failed to work.

I had a bit more success when using my Alexa Echo Dot (5th Gen); it was easy to add the Dyson skill on my Alexa app, and I could turn the purifier on and off, and ask to increase or decrease the fan speed. However, I couldn’t get it to switch to Auto mode or oscillate; instead, it would state the action request was not supported on the Dyson machine, which is disappointing at this price point.

From a fan perspective, the airflow was nice and smooth, and the strength was as I’d expect from one of Dyson’s bladeless tower fans. I found I could feel a noticeable breeze from around 3ft / 1m away on the lowest setting, 8ft / 2.4m on setting five, and 13ft / 4m on top setting ten.

The TP09 was speedy to react when I sprayed dry shampoo towards it from roughly 2 feet away, raising the PM2.5 reading to Severe almost instantly and upping the fan speed in response, swiftly returning the air quality reading within a minute of the contamination being detected.

The TP09 was quick to notice whenever I sprayed myself with perfume in the mornings, too, even though I was on the other side of the room. After promptly bumping the airflow up to setting five, it gradually lowered fan speed over the course of an hour. It didn’t have an impact on the fragrance in the air, which I was happy with in this instance, as my bedroom smelled pretty. But considering this alongside the performance of the TP10, which has the same filter, it looks likely that it’d struggle to make any noticeable effect on cooking smells without manually running it on a higher fan speed for a longer period of time.

I found it easy to sleep with the TP09 placed on the other side of my small nightstand, both in Night mode – which lowered the fan speed if I was running it higher and turned off the display – and when in standard Auto mode.

The decibel readings I got from the TP09 were, unsurprisingly, very similar to those of the TP10; with readings of 33dB on fan speed one, 43dB on speed five, and 52dB on speed ten. This means that its volume levels were similar to that of soft music at its quietest, and moderate rainfall at its loudest. The key difference between the two models is that the TP09 was not as quiet when in auto mode, as its superior detection skills meant that it didn’t relax and sit idling like the TP10.

Overall, I was very happy with the performance of the Dyson Purifier Cool Formaldehyde TP09 purifying fan, thanks to its prompt contamination detection and great level of detail and fine-tuning available in the fantastic companion app.

How I tested the Dyson Purifier Cool Formaldehyde TP09

• I used the Dyson TP09 purifying fan in my living room and bedroom
• I observed its detection and purification skills
• I evaluated the strength of the airflow and the sound levels

I used the Dyson Purifier Cool Formaldehyde TP09 purifying fan in our photo studio, my living room, and my bedroom over the course of a few weeks. I evaluated how easy it was to operate, along with the build quality and aesthetics, and explored the available functions and features.

I tested the strength of the airflow by determining at what distance I could still feel a cooling breeze. I also observed the TP09 Purifying Fan’s detection and purification skills during standardized testing, which included spraying dry shampoo towards it from around two feet away to test how quickly it would react and clear the contamination, and to see how it tackles odors. I also used it passively in my bedroom and my living room over a couple of weeks to see how it performed and how well it would report readings over time.

I used a decibel meter app on my iPhone to record the noise levels, taking readings from around two feet away and ensuring the fan wasn’t blowing directly into the microphone.

I checked the timer worked as expected, and tested out the sleep mode to see whether the TP09 was quiet enough for me to be able to sleep well with it running overnight.
