Our latest purifier detects and destroys formaldehyde,2 continuously

It combines a precise solid-state formaldehyde sensor with a unique catalytic filter that continuously destroys formaldehyde.2 HEPA H13 and activated carbon filters also capture dust, allergens, gases5 and other ultrafine pollutants. And Dyson purifiers have powerful Air Multiplier™ technology to purify the whole room.1


  • Proof of cleaner air

    Integrated sensors constantly analyse your air, while our unique algorithm cross-checks data every second. To precisely diagnose, display and react to pollutants at a molecular level, displaying live air quality results on the LCD screen and MyDyson.6

  • Captures gases and ultrafine particles

    The HEPA H13 filter captures 99.95% of particles as small as 0.1 microns.4 A layer of activated carbon also removes odours and gases including VOCs.5

  • Destroys formaldehyde, continuously

    The Dyson catalytic filter continuously traps and breaks down formaldehyde molecules into water and CO2. And it never needs replacing.

  • Whole room purification1

    Only Dyson purifiers have Air Multiplier™ technology. It generates the circulation power to draw even distant pollutants into the machine, projecting purified air throughout the room.1

  • Unlike others, what goes inside, stays inside

    In our latest purifiers, the whole purifier is sealed to HEPA H13 standard3 so what goes inside, stays inside.

  • Precisely detects formaldehyde

    Our latest purifiers use a solid-state sensor to detect formaldehyde molecules – 500 times smaller than 0.1 microns. Maintains precision for the lifetime of the machine.

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.

  • Graphic comparison of CADR test v Dyson test

    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.

  • Graphic comparison of CADR test v Dyson test

    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.
