TechRadar Verdict

The Dyson Purifier Cool Autoreact cools and purifies the air in a room. It's easy to set up and it looks attractive. However, it isn't app-compatible so the insights it offers are limited, and it takes some time to cool a room. It's expensive, too, which is likely to make it out of reach for many.

One minute review

Engineered in the UK and assembled in Malaysia, the Dyson Purifier Cool Autoreact TP7A Purifying Fan is one of a range of air treatment appliances that the brand offers; this model is designed to purify and cool the air in a room.

Dyson purifiers combine intelligent sensing with an advanced filtration system. The aim is to capture gases and 99.95% of particles as small as 0.1 microns in order to clean the air in the space in which it's placed. It's a fantastic solution for those who suffer allergies, or those who endure seasonal perils. The Dyson Purifier Cool Autoreact cools, too, oscillating 350° to circulate air.

Arriving with 10 speed settings, it includes a night mode and integrated sensors that analyse the air while it's in use. You can use the included controller to toggle through live results of air analysis on the LCD screen, as well as view the target temperature and filter status, so you know when the latter needs replacing.

We reviewed the Dyson Purifier Cool Autoreact during a spell of hot weather, late in summer 2022, where we'd say it proved it worth. Priced at $549.99 / £499.99, it's one of the most expensive coolers currently on sale – although the fact that it purifies the air too justifies the cost to a degree. However, it lacks the insight technology that we've now come to expect from this innovative brand, plus there's no app control available either. Nevertheless, the neat little controller does provide access to all the features and functions; it perches on the top of the appliance when not in use.

While we have pretty mixed feelings about the Dyson Purifier Cool Autoreact, ultimately, it's an impressive piece of kit, with nothing else like it currently available.

Dyson Purifier Cool Autoreact design

  • Oscillates up to 350°
  • Backward airflow mode
  • 10 speed settings

The Dyson Purifier Cool Autoreact TP7A Purifying Fan is a rather beautiful-looking appliance. Featuring smooth curves and standing tall, it comes in a white / silver color that will easily fit with most home decor.

Measuring 41 x 7.8 x 8.6in / 105 x 20.4 x 22cm (h x w x l), it makes a statement in the room, and its bladeless design makes it safe to use around young children. The battery-powered controller sits discretely on the top, secured by some sort of magnet that keeps it in place.

Setup was relatively straightforward. Out of the box, it was just the two filters that needed securing – one at the front and one at the back – and the two protective slides clipping on. The unit is mains-powered, so there's no need to pre-charge the Dyson Purifier Cool Autoreact before first use. However, note that the cable is only 5.9ft/1.8m long, so it can't be positioned too far away from a socket.

Setting up the Dyson Autoreact

In use, the Dyson Purifier Cool Autoreact can oscillate up to 350° – so, again, you'll need to consider placement in order to best benefit from sufficient air flow. To purify the air, backwards airflow mode diverts air through the rear of the machine, so we advise that the Dyson Purifier Cool Autoreact isn't positioned too close to the wall.

It arrives with 10 speed settings and a night time mode, allowing you to control the power and noise output. We tested it in our front room where we spend most of our time and in use we barely noticed it was running – aside from the gradual reduction in the temperature of the room.

Design: 5/5

Dyson Purifier Cool Autoreact performance

  • Quiet in use
  • Gradual cooling of the room
  • Senses and reports the air automatically

As an air purifier, the Dyson Purifier Cool Autoreact TP7A Purifying Fan proved brilliant. We used it mainly during a super-hot couple of weeks in September, the warm weather bringing with it a lot of irritating pollens. Following a couple of hours of use, the air in our front room felt noticeably lighter to breath. The Autoreact was set to oscillate and the low speed setting was more than sufficient. The filter didn't seem appear to take too much of a hit during those two weeks of relatively heavy use either.

In terms of cooling, yes, the temperature of the room did drop eventually. To say we were sweltering would be an understatement; we were in need of instant cooling, but the Dyson Purifier Cool Autoreact proved more of a slow burner. Even when on its highest speed setting, the results took some time to be felt.

Using the remote, it was interesting to toggle through the integrated sensors and reports to gain some insight into the air quality of the room in which the Autoreact was sat, as well as the status of the filter. The color LCD panel proved helpful on which to view the information the cooler/purifier provides; however, an accompanying app would likely deliver more room for detailed analysis.

The Dyson Purifier Cool Autoreact proved incredibly quiet in use, measuring in at 26db – 60db on our noise level meter, which is a similar pitch to rustling leaves on the lower speed and a normal conversation on the higher speed..

Dyson advise that you'll need to replace the filters every 12 months, and they can be bought direct from Dyson for $69.99/£65.99. Remember, you can keep an eye on filter status via the integrated reports, accessed via the controller.
