Poor air quality isn't just a problem outside. It's a problem inside too.

From plant pollen and cooking fumes, to VOCs and benzene found in sprays and candles, our homes can trap pollutants in the air. That's why Dyson purifiers automatically sense and remove them.

Captures and removes pollutants with HEPA air filtration

HEPA filter captures 99.95% of particles as small as 0.1microns.3 Many of the pollutants that can harm us aren’t visible and can evade detection. A HEPA air filter can capture and destroy tiny particles and allergens, improving the air quality standards of indoor spaces. Inclusion of a HEPA filter benefits the health of every inhabitant. The second, activated carbon filter absorbs gases, odours and VOCs for effective air treatment.

The Dyson Purifier Cool Autoreact™ is sealed to meet HEPA standard2

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 purifier.2 So what goes inside, stays inside.

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.

Senses and reports, for automatic air purification

Three sensors constantly analyse your air, while our unique algorithm cross-checks data every second. To precisely monitor, display and react to your air quality.

Frequently asked questions

There are many innovative features that work collectively tomake the Dyson Purifier Cool Autoreact an ideal air treatment solution for your home. One of many key features is its dynamic ability to sense and react to the world around you. This automatic air purifer is able to analyse air quality by running it through a unique algorithm of data to monitor and adapt to the needs of your surroundings.

We recommend replacing the HEPA+Carbon filter every 12 months. That's because over time, filters can get clogged with pollutants, and even let unpleasant odours back into the room. The machine will alert you when it’s time to change filters. A filter life reading can be found on the LCD screen.

HEPA filtration refers to filter quality and efficiency. Filters that meet HEPA (High Efficiency Particulate Air) standard can capture 99.95% of particles down to 0.1 microns3. This means that particle pollutants like bacteria, dust mites and allergens can be captured and destroyed, improving the health quality of homes.
