Air valve motor

The valve mechanism is driven by a brushless stepper motor, to allow remote actuation and switching between Diffused and Fan mode.

Air Multiplier™ technology

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

Real-time LCD screen

LCD screen reports indoor air quality in real time. The laser-etched display window is made from a single piece of impact-resistant polycarbonate shell.

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.²

Activated carbon filter

A layer of carbon captures gases⁵ 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 the Dyson Purifier range to be our first purifiers fully sealed to HEPA H13 standard. Capturing 99.95% of ultrafine particles and preventing pollutants from leaking back into the air you breathe.

What is different about the Dyson Purifier Formaldehyde range?

The Dyson Purifier Cool Formaldehyde has all of the capabilities found in our advanced purification products but goes a step further to detect and destroy formaldehyde. An added solid state-sensor precisely detects formaldehyde, while our catalytic filter breaks it down into two safer molecules – carbon dioxide and water.

What is formaldehyde and what are common sources of it?

Formaldehyde is a polluting gas formed of carbon, hydrogen and oxygen that is commonly found in homes. Common sources of formaldehyde in your home could be: paint and varnishes, air fresheners, mattresses, furniture, household cleaners, carpets, particleboard and plywood, electronics, dryer sheets, nail polish remover, moth balls, toys, fireplaces and wood burning stoves.

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. 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.
