Captures dust, allergens and bacteria. Even destroys formaldehyde.1
Fully-sealed to HEPA standard – what goes inside, stays inside.
Powerful circulation to purify the whole room3
Only Dyson purifiers have Air Multiplier™ technology, to draw in distant pollutants and project purified air throughout the room.3
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 gases5 and 99.95% of particles as small as 0.1 microns.2 Our catalytic filter continuously destroys formaldehyde1.
Destroys formaldehyde in billions of catalytic tunnels1
Dyson's unique catalytic filter continuously traps and converts formaldehyde into water and CO2. And it self-regenerates, so 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 purifier4. So what goes inside, stays inside.
Heats in winter. Cools you in summer.
In winter, Air Multiplier™ technology projects purified, heated air throughout the room.4 Once your target temperature is reached, heating automatically stops. In warmer weather, Air Multiplier™ projects over 290 litres of air a second for cooling airflow.
Smart purification, controlled by app or voice
Control and monitor air quality from anywhere with the Dyson Link app,6 or hands-free with compatible voice services.7
Diffused mode. Purifies without cooling you.
Airflow is diverted through the back of the machine, maintaining effective purification.
Oscillates up to 350 ̊
Adjustable oscillation projects purified air around the whole room.
For lighter sleepers, it monitors and purifies using the quietest settings along with a dimmed display.
Easy filter care
The catalytic filter never needs replacing. And when you need a new HEPA+Carbon filter, the Dyson Link app6 lets you know.
