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 H13 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.³
Senses and reports, automatically
Integrated sensors constantly analyze 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 particles
The HEPA H13 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 room
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
The purifier is fully sealed
Three phases of purification sit within our fully-sealed filtration and airflow system. To trap pollutants inside, removing them from the air you breathe.
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.
Cools you in summer
In warmer weather, a powerful stream of purified airflow can cool you down.
Diverts airflow through the back of the machine. To purify, without cooling you.
Now 20% quieter
Acoustically engineered to reduce turbulence, so it's 20% quieter than the previous model.
Control and monitor your air quality from anywhere using the Dyson Link app.⁴
Control it hands-free with compatible voice services.⁵
Oscillates up to 350 ̊
Adjustable oscillation projects purified air around the whole room.
For lighter sleepers. Monitors and purifies using the quietest settings, along with a dimmed display.

Frequently asked questions
Dyson engineers are perfectionists. Channelling our relentless dissatisfaction, we have re-engineered the Dyson Purifier range to be our first fully sealed purifiers. To trap pollutants inside, removing them from the air you breathe.
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.
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.
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.
