Long-range projection and circulation
Dyson Purifier Big+Quiet Formaldehyde uses cone aerodynamics to deliver powerful, long-range projection – circulating air and driving even distant pollutants back through sealed filters. For whole-room purification, even in large spaces.
Quiet, even at full power
An acoustically engineered motor bucket records just 56dBA of sound power at full-speed. With no compromise on performance.
Control your air quality wherever you are
The MyDyson™ app gives you autonomy over your air quality. View which particles have been captured, set schedules, browse reports, and more.
Hygienic filter replacement
A hygienic replacement mechanism allows you to dispose of the HEPA filter in one click.
Auto mode
With the Auto mode feature, your purifier can sense, capture and report on pollutants in your home in real-time. This saves energy – meaning it only purifies when needed.
Senses and reports, automatically
A suite of sensors, including a lifetime solid-state formaldehyde sensor, detects pollutants across a whole room in Dyson Purifier Big+Quiet Formaldehyde. Our unique algorithm cross-checks data every second, analysing your air at a molecular level – automatically reacting to purify and display live results on the LCD screen and in the MyDyson™ app.
Destroys formaldehyde, permanently
Dyson Purifier Big+Quiet Formaldehyde's catalytic filter continuously traps and breaks down formaldehyde molecules into water and CO25. And it never needs replacing.
Captures gases and ultrafine particles
The HEPA H13 grade filter captures 99.95% of ultrafine particles as small as 0.1 microns, while an activated carbon filter removes odours and gases.
Fully-sealed to HEPA H13 grade
Three phases of purification sit within our fully-sealed machine to trap pollutants inside, removing them from the air you breathe. Giving you reassurance that what goes inside, stays inside.
