Dyson’s most advanced filtration system combines a precise, solid-state formaldehyde sensor with a unique catalytic filter that continuously destroys formaldehyde. An activated carbon filter removes gases and odors and a HEPA filter captures 99.97% of particles 0.3 microns in size. And Dyson purifiers have powerful Air Multiplier™ technology to purify the whole room.

Automatically senses, captures and traps pollutants for cleaner air. Dyson purifiers are fully sealed, preventing pollutants from leaking back into the air. So what goes inside, stays inside.
