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 air purifiers automatically sense and remove them.

Pollutant sources in a living space and kitchen

Common household pollutants

  • Formaldehyde molecule


    Painting, varnishes and printers

  • Benzene molecule

    Benzene and VOCs

Dyson purifiers are tested beyond the industry standard

We test our purifiers in a room size of 81m³, with nine sensors that continuously measure air quality. Some other manufacturers use a small 28.5m³ chamber, with only one sensor and a fan to boost circulation.

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.

Senses and reports, automatically

Automatically detects, airborne particles and gases, then diagnoses and reports them in real time.

Captures with advanced HEPA filtration

The HEPA filter captures 99.95% of particles as small as 0.1 microns.3 Activated carbon absorbs gases5, odours and VOCs.

The purifier is sealed to HEPA standard4, removing 99.95% of particles as small as 0.1 microns.3

To prevent pollutants leaking back into the air, it's not just the filter that's sealed to HEPA H13 standard4, it's the whole purifier. So what goes inside, stays inside.

Frequently asked questions

Dyson purifier fans are engineered to provide powerful, personal cooling. They're not designed to lower the temperature of a whole room like an air conditioner does.

Dyson purifiers capture gases3 and 99.97% of particles from the air. Air Multiplier™ technology amplifies surrounding air, projecting a stream of powerful, smooth, high-velocity airflow. So they project purified, cleaner air throughout the room, or wherever you need it.5

Dyson air purifiers feature a Night mode. This mode uses the machine's quietest settings with dimmed display for lighter sleepers.

The Dyson Purifier Cool™ can control and monitor your home environment directly from your mobile device through the Dyson Link app. The Dyson Purifier Cool Autoreact™ has all of the benefits of a Dyson Purifier Cool™ without the app connectivity.
