Automatically senses, reacts and displays real-time air quality
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 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.
Senses and reports, automatically
Three sensors interact with our unique algorithm to precisely diagnose, display and react to your air quality.
Captures and removes with advanced HEPA filtration
The HEPA+Carbon filter captures gases and 99.95% of particles as small as 0.1 microns.2
The only purifier fully sealed to HEPA H13 standard
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 purifier3. So what goes inside, stays inside.
Fast, even room heating
Air Multiplier™ technology projects purified, heated air throughout the room.4 Once your target temperature is reached, heating automatically stops.

2 Tested for filtration efficiency at 0.1 microns (EN1822, ISO29463). Gas capture rates vary.
3 Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. Tested in Max Mode at IBR US, for whole machine efficiency above 99.95%.
4 In maximum setting. Tested for air projection, purification coverage in a 81m3 room.
5 Whole machine tested by independent third-party laboratory Airmid (Ireland) in 28.5m3 test chamber pre-conditioned to 20±3C and RH 50±5%. Influenza A (H1N1) aerosolised in the test chamber and airborne concentration observed for the duration of 60 minutes under maximum Fan speed. Dyson Purifier achieved [xx.xx%] efficacy but real life efficacy may differ depending on actual environment and Fan speed. Tested on Influenza A (H1N1) only.
