Dyson Purifier Cool Formaldehyde Purifying Fan, 40W, 74 sqm Coverage, Nickel/Gold - eXtra

Captures dust, allergens and H1N1 virus. Even destroys formaldehyde

Powerful circulation to purify the whole room

Only Dyson purifiers have Air Multiplier™ technology, to draw in distant pollutants and project purified air throughout the room.

CADR is not a measure of purification performance in a real-size room 28.5m3

Two additional fans boost circulation. Only one sensor measures air quality.

Dyson's POLAR test goes further to measure purification throughout a real-size room 81m3

No additional fans. Nine different sensors to measure even-room air quality.

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.

Senses and reports, automatically

Four sensors, including a solid-state formaldehyde sensor, interact with our unique algorithm to precisely diagnose, display and react to your air quality.

Captures and destroys with advanced HEPA filtration

The HEPA+Carbon filter captures gases and 99.95% of particles as small as 0.1 microns.2 Our catalytic filter continuously destroys formaldehyde.

Destroys formaldehyde in billions of catalytic tunnels

Dyson's unique catalytic filter continuously traps and converts formaldehyde into water and CO2. And it self-regenerates, so it never needs replacing.

The only purifier fully sealed to HEPA H13 standard

To prevent pollutants leaking back into the air, it's not just the filter that's sealed to HEPA H13 standard, it's the whole purifier . So what goes inside, stays inside.

Smart purification, controlled by app or voice

Control and monitor air quality from anywhere with the Dyson Link app, or hands-free with compatible voice services.

Diffused mode. Purifies without cooling you

Airflow is diverted through the back of the machine, maintaining effective purification.

Night mode

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

20% quieter

Acoustically engineered to reduce turbulence, so it's 20% quieter than the previous model.

Easy filter care

The catalytic filter never needs replacing. And when you need a new HEPA+Carbon filter, the Dyson Link app lets you know.
