Dyson Purifier Cool™ gen1 purifying fan. Automatically senses and captures pollutants to purify your whole room. Fully-sealed to HEPA standard – what goes inside, stays inside.
Whole-room purification
Only Dyson purifiers have Air Multiplier™ technology, to draw in distant pollutants and project 290 litres of purified air throughout the room.
Senses and reports, automatically
Sensors constantly analyse your air, while the unique algorithm cross-checks data per second. To precisely monitor, report and improve your air quality.
360 HEPA H13 filter
9 metres of borosilicate microfibres, pleated over 200 times capture 99.95% of pollutants as small as 0.1 microns.2
Activated Carbon filter
A layer of activated carbon captures gases such as benzene and NO2 emitted from cleaning products, candles and gas stoves.
The only purifier fully sealed to HEPA H13 standard
To prevent pollutants leaking back into the air, it's not just the filter that's sealed to HEPA H13 standard, it's the whole purifier4. So what goes inside, stays inside.
