Dyson air 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.

  • CADR test chamber

    Industry-standard test chamber – only 28.5m³

  • Polar test chamber

    Dyson POLAR test chamber - 81m³

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.

Common household pollutants

  • Household fumes and cooking

    Odors

  • Cleaning products and candles

    Benzene and VOCs

  • Gas stoves and car exhausts

    Nitrogen Dioxide

  • Pollen and allergens

    PM10

  • Bacteria

    PM5.0

  • Industrial emissions and house dust

    PM2.5

  • Ultrafine particles

    PM0.1

     

Air purifier Cool Autoreact 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.

Dyson air purifier filtration system

Captures and removes with HEPA filtration

The HEPA+Carbon filter captures gases and 99.97% of particles as small as 0.3 microns.

Fully sealed air 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.³ So what goes inside, stays inside.

Additional features

  • Purified air exiting the back of the air purifier

    Backward airflow mode. Purifies without cooling you.

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

  • Dyson air purifier in a dark bedroom with someone sleeping peacefully

    Night mode

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

  • Dyson air purifier in a bedroom

    20% quieter

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

  • Air purifier filter being changed

    Easy filter care

    Your HEPA+Carbon filter is easy to change and the LCD screen will alert you when it's time.

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.
