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.

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.
*Product and filter Images may vary depending on the market and production batch. Product performance is not impacted.

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 H13 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.
