Watch to discover how we test our purifiers' HEPA filters are fully-sealed, with no pollutants or allergens leaking out.
Captures and destroys with advanced HEPA filtration
The HEPA filter captures gases and 99.97% of particles as small as 0.3 microns. Our catalytic filter continuously destroys formaldehyde.
Dyson's unique catalytic filter continuously traps and converts formaldehyde into water and CO₂. And it self-regenerates, so it never needs replacing.¹
To prevent pollutants from leaking back into the air, it's not just the filter that's sealed to HEPA H13 standard, it's the whole purifier.³ So what goes inside, stays inside.
Only Dyson purifiers have Air Multiplier™ technology to draw in distant pollutants and project purified air throughout the room.²
We test beyond the industry standard. For real living spaces.
Dyson engineers designed the POLAR test to challenge the industry test standard – measuring filtration, sensing and circulation to ensure the whole room is purified properly.
Two additional fans boost circulation. Only one sensor measures air quality.
No additional fans. Nine different sensors to measure even-room air quality.

We're spending more time indoors, in increasingly well-insulated homes and workplaces. Over time, these common indoor air pollutants can build up.

Volatile organic compounds (VOCs) are potentially harmful gases emitted by household sprays, air fresheners and personal care products. If used regularly in unventilated rooms, VOC concentrations increase.

Another potentially harmful gas is formaldehyde, released by some furniture, paints, mattresses, carpets and fireplaces. Most homes contain formaldehyde, but amounts spike during interior decoration projects.

Cooking can release a unique mix of combustion pollutants and airborne particles. Even after cooking, odours and potentially harmful contaminants can remain in the air.

Pets can introduce allergens, bacteria and viruses into the home. When pets groom themselves, they deposit protein particles from their saliva onto their hair and skin. These microscopic skin cells dry and flake off to form pet dander.

Automatic sensing, a fully-sealed machine and long-range air projection are key to effective air purification. That's why they're at the core of our technology. And why we've been testing them for generations.
Reacts automatically to remove pollutants, only using energy when needed.¹

Dyson Air Multiplier™ technology projects purified air into every corner of the room.³
Control your air purifier from anywhere with your smart device, whether you’re traveling, at work, or simply at home on the sofa.
Monitor indoor and outdoor air quality from your smart device. See your machine’s activity as well as temperature, humidity, and filter reports.
You’ll never need to worry about when to replace your filter. We’ll let you know. Helping your machine to always perform at its best.
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.
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.
