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.

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.

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.

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.

Adsorbs 3x more NO2

Our K-Carbon filter is impregnated with potassium carbonate (K2CO3) and can adsorbs three times more nitrogen dioxide4 - one of the most common indoor pollutants, produced by gas appliances, open flames, and wood burning stoves.

Senses and reports CO2 levels in real-time

Increased CO2 levels can impact cognitive function. Dyson Purifier Big+Quiet Formaldehyde intelligently senses and reports CO2 levels, notifying when they exceed recommended volumes9, alerting you on the MyDyson™ app or LCD screen when to ventilate by opening a door or window.

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, permanently

A 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.
