Captures up to 99.9% of human coronaviruses 229E and OC43 aerosol11. Even destroys formaldehyde.1
Captures H1N1, H3N2, EV71 viruses7, bacteria & allergens.
Purifies the whole room3
Fully sealed to HEPA H13 standard4
Powerful circulation to purify the whole room
Only Dyson purifiers have Air Multiplier™ technology, to draw in distant pollutants and project purified air throughout the room.3
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.
Poor air quality isn't just a problem outside. It's a problem inside too.
From pets and flowers, to sprays and stoves, our homes can trap pollutants in the air. Formaldehyde can also be released from common household items like wood, indoor paints & furniture for years. That's why Dyson purifiers automatically sense and remove them.

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 purifier is 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 standard, it's the whole purifier4. So what goes inside, stays inside.
Engineered for pets
Captures 99.95% of small particles such as pet dander2. And removes up to 97% of cat urine odour10.
