Pioneering Dyson technology

Explore the engineering behind the Dyson Purifier Cool Formaldehyde

Air Multiplier technology

Projects a long-range stream of smooth air. No need for blades.

Formaldehyde sensor

Solid state electrochemical cells precisely detect formaldehyde for the lifetime of the machine.

Gas and particulate sensors

Measures and detects particles and volatile organic compounds in the air.

360 HEPA H13 filter

9 metres of borosilicate microfibres, pleated over 200 times, captures 99.95% of pollutants as small as 0.1 microns.1

Selective catalytic oxidisation filter

Traps formaldehyde in catalytic tunnels, continuously breaking it down into water and CO2.

Activated carbon filter

A layer of carbon captures gases1 such as benzene and NO2.

Frequently asked questions

What is new about the Dyson Purifier range and how is it different to other purifiers?

Dyson engineers are perfectionists. Channelling our relentless dissatisfaction, we have re-engineered our latest’s purifiers to be the only purifier fully sealed to HEPA H13 standard. Capturing 99.95% of ultrafine particles and preventing pollutants from leaking back into the air you breathe.

How often should I replace my filter?

We recommend replacing the HEPA+Carbon filter every 12 months. That's because over time, filters can get clogged with pollutants, and even let unpleasant odours back into the room. The machine will alert you when it’s time to change filters. A filter life reading can be found on the LCD screen and via the Dyson Link app. The catalytic filter never needs replacing.

  • 1 Tested for filtration efficiency at 0.1 microns (EN1822, ISO29463). Dyson purifiers were challenged with airborne influenza A (H1N1 virus) and MS2 bacteriophage at an independent lab, using a 30 m3 chamber. After 60 minutes at maximum fan speed, the airborne concentration in the chamber was reduced up to 99.9 %. Real-life efficacy may vary.
  • 2 Dyson purifiers were challenged with airborne SARS-CoV-2 (the virus that causes COVID-19) at an independent lab, using a 0.37 m3 chamber for 90 seconds. Dyson Purifiers were also challenged with Phi-6 bacteriophage (a surrogate to test SARS-CoV-2) at an independent lab, using a 30 m3 chamber. After 90 minutes at maximum fan speed, the airborne concentration in the chamber was reduced by 99.9 %. Real-life efficacy may vary.
  • 3 Particle challenge by DHES oil specified in EN1822 within a chamber of specified in ATSM F3150. Tested in max mode at IBR US, for w whole machine efficiency above 99.95%.
  • 4 Gas capture rates may vary.
  • 5 Requires device to run app, Wi-Fi or mobile data, Bluetooth 4.0 support, and iOS version 10 or Android version 5 (or above). Standard data and messaging rates may apply.
  • 6 Refer to the Dyson Link App for comptible voice services.
