Our latest purifier detects and destroys formaldehyde, continuously

It combines a precise solid-state formaldehyde sensor with a unique catalytic filter that continuously destroys formaldehyde. HEPA and activated carbon filters also capture dust, allergens, gases² and other pollutants. And Dyson purifiers have powerful Air Multiplier™ technology to purify the whole room.


  • Heats in winter

    With long-range projection, it’s quick to heat the whole room evenly.³

  • Cools you in summer

    In warmer weather, a powerful stream of purified airflow can cool⁷ you down.

  • Backward airflow mode

    Diverts airflow through the back of the machine. To purify, without cooling you.

  • App control

    Control and monitor your air quality from anywhere using the Dyson Link app.⁵

  • Oscillates up to 350 ̊

    Adjustable oscillation projects purified air around the whole room.

  • Voice control

    Control it hands-free with compatible voice services.⁶

  • Night mode

    For lighter sleepers. Monitors and purifies using the quietest settings, along with a dimmed display.

  • Easy filter care

    The filter is quick and easy to change. With automatic filter-life notifications on the LCD or Dyson Link app.⁵

  • Remote

    Curved and magnetized to store neatly on top of the machine.


  • Senses and reports, automatically

    Integrated sensors constantly analyse your air, while our unique algorithm cross-checks data every second. It diagnoses pollutants at a molecular level, displaying live results on the LCD.

  • Captures gases and ultrafine particles

    The HEPA filter captures 99.97% of particles as small as 0.3 microns. A layer of activated carbon also removes odours and gases including VOCs.²


  • Destroys formaldehyde, continuously

    The Dyson catalytic filter continuously traps and breaks down formaldehyde¹ molecules into water and CO2. And it never needs replacing.

  • Purifies the whole room³

    Dyson purifiers have Air Multiplier™ technology. It generates the circulation power to draw even distant pollutants into the machine, projecting purified air throughout the room.³

  • Fully sealed to HEPA H13⁴

    In our latest purifiers, it’s not just the filter that meets HEPA H13 standard, it’s the whole machine.⁴ So what goes inside, stays inside.

  • Precisely detects formaldehyde

    Our latest purifiers use a solid-state sensor to detect formaldehyde molecules – 500 times smaller than 0.1 microns. Maintains precision for the lifetime of the machine.
