Captures and removes pollutants with HEPA air filtration
HEPA filter captures 99.95% of particles as small as 0.1microns.3 Many of the pollutants that can harm us aren’t visible and can evade detection. A HEPA air filter can capture and destroy tiny particles and allergens, improving the air quality standards of indoor spaces. Inclusion of a HEPA filter benefits the health of every inhabitant. The second, activated carbon filter absorbs gases, odours and VOCs for effective air treatment.

The Dyson Purifier Cool Autoreact™ is sealed to meet HEPA standard2
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.2 So what goes inside, stays inside.
