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

When summer temperatures rise, so can pollution levels

Summer heat can increase levels of indoor ozone. This gas can react with VOCs to produce higher levels of ultrafine particles.

  • Internal sensing technology and LCD screen showing air quality

    Senses and reports, automatically

    Integrated sensors constantly analyse your air, while our unique algorithm cross-checks data every second. It diagnoses pollutants at a molecular level, displaying live results on the LCD.

    Whole room purification1

    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, it's not just the filter that meets HEPA H13 standard4, it's the whole machine. 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.

    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, automatically

Four sensors, including a solid-state formaldehyde sensor, interact with our unique algorithm to precisely diagnose, display and react to your air quality.

Captures and destroys with advanced HEPA filtration

The HEPA+Carbon filter captures gases5 and 99.95% of particles as small as 0.1 microns.3 Our catalytic filter continuously destroys formaldehyde2.

The purifier is sealed to HEPA H13 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.
