Technology
-
Advanced automatic sensing
Senses microscopic particles, gases⁴, VOCs, NO₂, humidity, temperature and formaldehyde.³ Reacts automatically to detect, track and remove pollutants.
-
Fully-sealed filtration to HEPA H13 standard
Advanced whole-machine fully-sealed filtration with HEPA H13, Activated carbon and SCO filters. So the pollution captured inside, stays inside.⁶
-
Powerful long-range air projection⁵
Air Multiplier™ technology projects up to 290 litres of air per second to circulate purified air and heat across the whole room.¹
Key features
-

Technology
-
Senses and reports, automatically
Integrated sensors constantly analyse your air, while our unique algorithm cross-checks data every second. It diagnoses pollutants at a molecular level, displaying live results on the LCD.
-
Captures gases and ultrafine particles
The HEPA filter captures 99.97% of particles as small as 0.3 microns. A layer of activated carbon also removes odours and gases including VOCs.²
-
Destroys formaldehyde, continuously
The Dyson catalytic filter continuously traps and breaks down formaldehyde¹ molecules into water and CO². And it never needs replacing.
-
Purifies the whole room³
Dyson purifiers have Air Multiplier™ technology. It generates the circulation power to draw even distant pollutants into the machine, projecting purified air throughout the room.³
-
Fully sealed to HEPA H13⁴
In our latest purifiers, it's not just the filter that meets HEPA H13 standard, it's the whole machine.⁴ So what goes inside, stays inside.
-
Precisely detects formaldehyde
Our latest purifiers use a solid-state sensor to detect formaldehyde molecules – 500 times smaller than 0.1 microns. Maintains precision for the lifetime of the machine.
