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.
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
Four sensors, including a solid-state formaldehyde sensor, interact with our unique algorithm to precisely diagnose, display and react to your air quality.
Captures and destroys with advanced HEPA filtration
The HEPA+Carbon filter captures gases and 99.95% of particles as small as 0.1 microns.2 Our catalytic filter continuously destroys formaldehyde1.
Destroys formaldehyde, continuously
The Dyson catalytic filter continuously traps and breaks down formaldehyde1 molecules into water and CO₂. And it never needs replacing.
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 MultiplierTM technology projects purified, heated air throughout the room.4 Once your target temperature is reached, heating automatically stops.
Smart purification, controlled by app or voice
Control and monitor air quality from anywhere with the MyDyson app,6 or hands-free with compatible voice services.7
