Only Dyson purifiers have Air Multiplier™ technology, to draw in distant pollutants and project purified air throughout the room.3

Dyson purifier hot+cool formaldehyde purifying a large living space

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. That's why Dyson purifiers automatically sense and remove them.

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.
