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.2
Dyson purifier inside Dyson test chamber with nine sensors

Dyson purifiers are tested beyond
the industry standard

We test our purifiers in a room size of 81m³, with nine sensors that continuously measure air quality. Some other manufacturers use a small 28.5m³ chamber, with only one sensor and a fan to boost circulation.
Pollutant sources in a living space

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

From plant pollen and cooking fumes, to VOCs and benzene found in sprays and candles, our homes can trap pollutants in the air. That's why Dyson purifiers automatically sense and remove them.

Captures microscopic particles and gases

The fully-sealed filtration system captures many common household pollutants Including formaldehyde, pollen, bacteria and odours.

Internal sensing technology and LCD screen showing air quality

Senses and reports, automatically

Three sensors constantly analyse your air, while our unique algorithm cross-checks data every second. To precisely monitor, display and react to your air quality.

Captures and removes with HEPA filtration

HEPA filter captures 99.95% of particles as small as 0.1 microns.² Activated carbon absorbs gases⁵, odours and VOCs.

Only Dyson’s latest purifiers are fully sealed to HEPA H134
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.4 So what goes inside, stays inside.

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.
