Air valve motor

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

Air Multiplier technology

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

PTC plates

Air circulates between the plates and external casing, to heat the air as it leaves the machine.

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.

Pollutant sources in a living space and kitchen

Poor air quality isn't just a problem outside.
It's a problem inside too.

From pets and flowers, to sprays and stoves, our homes can trap pollutants in the air. That's why Dyson purifiers automatically sense and remove them.

Overall rating

Excellent air purifier

Stargazer7

I’ve upgraded to this formaldehyde detecting air purifier. I have very sensitive asthma, sensitive to salicylates, perfumes, VOCs, formaldehyde. This machine helps a great deal in cleaning but also identifying the presence of such problems, which allows me to improve the home environment further. It has, for example, confirmed what I always suspected, that a gas hob in the kitchen is not good for my breathing. On course to change it for electric!

      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.

      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 and via the Dyson Link app. The catalytic filter never needs replacing.
