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.

    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 constantly monitor your air, while our unique algorithm diagnoses pollutants at a molecular level – reacting to purify and display live air quality.

Solid-state formaldehyde sensor. For lifetime precision.

Our latest purifiers use an electrochemical cell to precisely detect formaldehyde molecules – 500 times smaller than 0.1 microns. And because it's solid state, it maintains precision for the lifetime of the machine.

Captures and destroys with advanced HEPA H13 filtration

The Dyson catalytic filter continuously destroys formaldehyde1, while our HEPA+Carbon filter captures gases5 and 99.95% of particles as small as 0.1 microns2.

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.

1 Third party full machine testing based on GB/T 18801-2015 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice.
2Tested for filtration efficiency at 0.1 microns (EN1822, ISO29463).
3In maximum setting. Tested for air projection, purification coverage in a 81m3 room.
4 Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. Tested in Max Mode at IBR US, for whole machine efficiency above 99.95%.
5Gas capture rates may vary.
6 Requires device to run app, Wi-Fi or mobile data, Bluetooth 4.0 support, and iOS version 10 or Android version 5 (or above). Standard data and messaging rates may apply. App control doesn’t apply to heating.
7Refer to the Dyson Link app for compatible voice services.
8We challenged our purifier with airborne influenza A (H1N1 virus) at an independent lab. After 60 minutes at maximum fan speed, the airborne concentration in the chamber was reduced by 99%. Real-life efficacy may vary.
