Indoor activities that contirubte to indoor air pollution

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 air purifiers automatically sense and remove them.

Pollutant sources in a living space and kitchen

When summer temperatures rise, so can pollution levels

Summer heat can increase levels of indoor ozone. This gas can react with VOCs to produce higher levels of ultrafine particles.

  • Proof of cleaner air

    Sensors precisely diagnose, display and react to pollutants at a molecular level, displaying live air quality results on the LCD screen and MyDyson™ App.6

  • Unlike others, what goes inside, stays inside

    The whole purifier is sealed to HEPA H13 standard4, removing 99.95% of particles as small as 0.1 microns.3

  • Whole room purification1

    Air Multiplier™ technology draws in distant pollutants and projects purified air throughout the whole room.1

We test beyond the industry standard. For real living spaces.

Dyson engineers designed the POLAR air purification test to challenge the industry test standard – measuring filtration, sensing and circulation to ensure the whole room is purified properly.

    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.

Senses and reports, automatically

Automatically detects, airborne particles and gases, then diagnoses and reports them in real time.

Captures with advanced HEPA filtration

The HEPA filter captures 99.95% of particles as small as 0.1 microns.3 Activated carbon absorbs gases4, odours and VOCs.

To prevent pollutants leaking back into the air, it's not just the filter that's sealed to HEPA H13 standard4, it's the whole purifier. So what goes inside, stays inside.

Frequently asked questions

Dyson engineers are perfectionists. Channelling our relentless dissatisfaction, we have re-engineered our latest’s purifiers so the whole machine is now sealed to meet HEPA H13 standard.4 Capturing 99.95% of ultrafine particles and preventing pollutants from leaking back into the air you breathe.

The Dyson Purifier Hot+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 doesn't need replacing.
