Overall rating
Powerful circulation to purify the whole room²
Only Dyson purifiers have Air Multiplier™ technology, to draw in distant pollutants and project purified air throughout the room.²
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.

Industry-standard test chamber – only 28.5m³

Dyson POLAR test chamber - 81m³
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.

Senses and reports, automatically
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.
Captures and removes with HEPA filtration
HEPA filter captures 99.95% of particles as small as 0.1 microns.² Activated carbon absorbs gases⁵, odours and VOCs.
Only Dyson’s latest purifiers are fully sealed to HEPA H13⁴
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.⁴ So what goes inside, stays inside.

Frequently asked questions
Dyson engineers are perfectionists. Channelling our relentless dissatisfaction, we have re-engineered the Dyson Purifier range to be our first purifiers fully sealed to HEPA H13 standard. 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. The catalytic filter never needs replacing.
