Dyson Purifier Hot+Cool Formaldehyde
Captures dust, allergens and H1N1 virus⁸. Even destroys formaldehyde.¹
Removes 99.95% of ultrafine particles2
Purifies and heats the whole room3
Fully-sealed to HEPA standard – what goes inside, stays inside4
We test beyond the industry standard. For real living spaces.
Dyson engineers designed the POLAR test to challenge the industry test standard – measuring filtration, sensing and circulation to ensure the whole room is purified properly.
CADR is not a measure of purification performance in a real-size room 28.5m³
Two additional fans boost circulation. Only one sensor measures air quality.
Dyson's POLAR test goes further to measure purification throughout a real-size room 81m³
No additional fans. Nine different sensors to measure even-room air quality.
Senses and reports, automatically
Four sensors, including a solid-state formaldehyde sensor, interact with our unique algorithm to precisely diagnose, display and react to your air quality.
Captures and destroys with advanced HEPA filtration
The HEPA+Carbon filter captures gases5 and 99.95% of particles as small as 0.1 microns.2 Our catalytic filter continuously destroys formaldehyde1.
Destroys formaldehyde in billions of catalytic tunnels1
Dyson's unique catalytic filter continuously traps and converts formaldehyde into water and CO2. And it self-regenerates, so it never needs replacing.
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.
Fast, even room heating
Air Multiplier™ technology projects purified, heated air throughout the room.4 Once your target temperature is reached, heating automatically stops.
Smart purification, controlled by app or voice
Control and monitor air quality from anywhere with the Dyson Link app,6 or hands-free with compatible voice services.7
Cools you in summer
Projects over 290 litres of air a second for cooling airflow.
Diffused mode. Purifies without cooling you.
Airflow is diverted through the back of the machine, maintaining effective purification.
For lighter sleepers, it monitors and purifies using the quietest settings along with a dimmed display.
Easy filter care
The catalytic filter never needs replacing. And when you need a new HEPA+Carbon filter, the Dyson Link app6 lets you know.
