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.

An acoustically engineered motor bucket records just 56dBA of sound power at full-speed. With no compromise on performance.

The MyDyson™ app gives you autonomy over your air quality. View which particles have been captured, set schedules, browse reports, and more.

A hygienic replacement mechanism allows you to dispose of the HEPA filter in one click.

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.

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.

Dyson Purifier Big+Quiet Formaldehyde's catalytic filter continuously traps and breaks down formaldehyde molecules into water and CO25. And it never needs replacing.

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.

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.
