Purifies and heats the whole room2

Sealed to HEPA standard – what goes inside, stays inside3

Dyson purifier hot + cool

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.

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 purifiers automatically sense and remove them.

The purifier is sealed to HEPA H13 standard3, removing 99.95% of particles as small as 0.1 microns.7

To prevent pollutants leaking back into the air, it's not just the filter that's sealed to HEPA H13 standard,3 it's the whole purifier. So what goes inside, stays inside.

Frequently asked questions

Dyson engineers are perfectionists. Channelling our relentless dissatisfaction, we have re-engineered our latest’s purifiers so the whole machine is now sealed to meet HEPA H13 standard3 . Capturing 99.95% of ultrafine particles and preventing pollutants from leaking back into the air you breathe.

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 and via the Dyson Link app.
