Features
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

Technology
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^5
A catalytic filter continuously traps and breaks down formaldehyde molecules into water and CO2^5. And it never needs replacing.

Captures gases and ultrafine particles^2
The HEPA H13 grade filter captures 99.95% of ultrafine particles as small as 0.1 microns^2, while an activated carbon filter removes odours and gases.^3

Fully-sealed to HEPA H13 grade^6
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

^1 The ability of purifying a large room up to 100m2 (10m*10m) proven from a Computational Fluid Dynamics (CFD) modelling, with the purifier placed in a corner of the room running at the maximum flow and horizontal projection reaching 10 metres to fully mix the room. The projection distance was measured from internal flow reach testing under the maximum directional airflow. The actual performance in real life condition may vary.
^2 Tested for filtration efficiency at 0.1 microns (EN1822, ISO29364).
^3 Tested to JEM 1467 (acetic acid, acetaldehyde, ammonia), GB/T18801 (formaldehyde, benzene) and DTM-003282 (NO2). Gas capture rates vary.
^4 Compared to adsorption by the standard carbon filter in Dyson Purifier Big+Quiet Formaldehyde (BP03).
^5 Third party full machine testing based on GB/T 18801-2022 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice.
^6 Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. Tested in Max Mode at IBR US, for whole machine efficiency above 99.95%.
^7 Tested on Korean BBQ, grilled salmon, cat urine, tobacco smoke and garbage odours.
^8 App functionality may vary per market. Requires Wi-Fi and app enabled device. Standard data and messaging rates may apply. Requires iOS version 10 or above, or Android version 5 or above. Your mobile device must have Bluetooth 4.0 support.
^9 Levels defined by Dyson based on scientific literature. Ventilation alert when CO2 levels are 1500ppm or above.
^11 In Auto mode.
