Dyson - Purifier Big+Quiet Formaldehyde BP03 - Nickel and Prussian blue

Long-range projection and circulation

Our latest purifier 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.¹

Quiet, even at full power

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

Adjust your airflow

Adjust the angle of airflow at 0°, 25° or 50°, or mimic the feeling of refreshing air indoors using Breeze mode.

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.⁸

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.¹¹

Hygienic filter replacement

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

Discreet wheels

Easily manoeuvre your machine across a room. Designed for hard surfaces, the wheels are completely hidden from view.

Smart home purification

Connect and then control your air quality, hands-free, with compatible smart home voice services.¹³

Senses and reports, automatically

A suite of sensors, including a lifetime solid-state formaldehyde sensor, detects pollutants across a whole room. 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, permanently⁵

A catalytic filter continuously traps and breaks down formaldehyde molecules into water and CO₂⁵. And it never needs replacing.

Captures gases and ultrafine particles²

The HEPA H13 grade filter captures 99.95% of ultrafine particles as small as 0.1 microns², while an activated carbon filter removes odours and gases.³

Fully-sealed to HEPA H13 grade⁶

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.⁶
