  • Dyson Purifier Big+Quiet Formaldehyde in a large space.

    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

  • Zoomed-in look at the sensor technology on the Dyson Purifier Big+Quiet Formaldehyde.

    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.

  • Gases and ultrafine particles flowing through filtration.

    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

Frequently asked questions

Sources of formaldehyde can include woods, glues, paints, varnishes, air fresheners, mattresses, household cleaners, and some fabrics found in household flooring and furniture. The Dyson Formaldehyde air purifier range includes a catalytic filter that traps formaldehyde in tunnels, breaking it down into water and CO2.5

The Dyson Purifier Big+Quiet Formaldehyde has our largest ever filtration system. We recommend replacing the H13 grade HEPA filter after using it for up to five years or sooner. The activated carbon filter should be replaced every two years or sooner if required. The selective catalytic oxidisation filter is permanent and never needs replacing.

The Dyson Purifier Big+Quiet Formaldehyde has been designed to work from the corner of a room, at least one metre away from the wall. For optimal performance we recommend projecting air either along a wall or across the room. You can adjust the angle of projection to suit your preference. ​

The Dyson Purifier Big+Quiet Formaldehyde has discreet wheels which are not visible when the product is upright. These wheels are designed for hard floors – so you can move your purifier around easily.

Our quietest most
powerful purifier


1The 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.
2Tested for filtration efficiency at 0.1 microns (EN1822, ISO29364).
3Tested to JEM 1467 (acetic acid, acetaldehyde, ammonia), GB/T18801 (formaldehyde, benzene) and DTM-003282 (NO2). Gas capture rates vary.
4Compared to adsorption by the standard carbon filter in Dyson Purifier Big+Quiet Formaldehyde (BP03).
5Third 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.
6Particle 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%.
8App 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.
9Levels defined by Dyson based on scientific literature. Ventilation alert when CO2 levels are 1500ppm or above.
