Air valve motor

The valve mechanism is driven by a brushless stepper motor, to allow remote actuation and switching between Diffused mode and Fan mode.

Air Multiplier technology

Projects a long-range stream of smooth air. No need for blades.

PTC plates

Air circulates between the plates and external casing, to heat the air as it leaves the machine.

Formaldehyde sensor

Solid state electrochemical cells precisely detect formaldehyde for the lifetime of the machine.

Gas and particulate sensors

Measures and detects particles and volatile organic compounds in the air.

360 HEPA H13 filter

9 metres of borosilicate microfibres, pleated over 200 times, captures 99.95% of pollutants as small as 0.1 microns.1

Selective catalytic oxidisation filter

Traps formaldehyde in catalytic tunnels, continuously breaking it down into water and CO2.

Activated carbon filter

A layer of carbon captures gases1 such as benzene and NO2.

Dyson purifier hot+cool formaldehyde purifying a large living space

Powerful circulation to purify the whole room³

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

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.

    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.

  • Graphic comparison of CADR test v Dyson test

    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.

Pollutant sources in a living space and kitchen

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.

Common household pollutants

  • Common allergens - pet dander, pollen and dust

    PM10

  • Bacteria and mold spores

    PM5.0

  • Industrial emissions and smoke

    PM2.5

  • Ultrafine particles

    PM0.1

  • Formaldehyde (HCHO)

    Carpets, rugs and flooring

  • Odours

    Household fumes and cooking

  • Benzene and VOCs

    Cleaning products and candles

  • Nitrogen dioxide

    Gas stoves and car exhausts

Internal sensing technology and LCD screen showing formaldehyde detected

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 an advanced HEPA filtration system

The HEPA+Carbon filter captures gases⁵ and 99.95% of particles as small as 0.1 microns.² Our catalytic filter continuously destroys formaldehyde¹.

Destroys formaldehyde in billions of catalytic tunnels¹

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

Graphic showing fully sealed purifier

The purifier is fully sealed to HEPA H13

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 and via the Dyson Link app. The catalytic filter never needs replacing.

  • 1 Third party full machine testing based on GB/T 18801-2018 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice.
  • 2 Tested for filtration efficiency at 0.1 microns (EN1822, ISO29463)
  • 3 In maximum setting. Tested for air projection, purification coverage in an 81m³ room and heating performance in a 35m³ room.
  • 4 Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. Tested in Max Mode at IBR US, for whole machine efficiency above 99.95%.
  • 5 Gas capture rates may vary.
  • 6 Requires device to run app, Wi-Fi or mobile data, Bluetooth 4.0 support, and iOS version 10 or Android version 5 (or above). Standard data and messaging rates may apply. App control doesn’t apply to heating.
  • 7 Refer to the Dyson Link app for compatible voice services.
