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.
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.
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 advanced HEPA filtration
The HEPA+Carbon filter captures gases and 99.95% of particles as small as 0.1 microns.2 Our catalytic filter continuously destroys formaldehyde1.
Destroys formaldehyde, continuously
The Dyson catalytic filter continuously traps and breaks down formaldehyde1 molecules into water and CO₂. And it never needs replacing.
The only 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 purifier3. So what goes inside, stays inside.
Fast, even room heating
Air MultiplierTM technology projects purified, heated air throughout the room.4 Once your target temperature is reached, heating automatically stops.
Smart purification, controlled by app or voice
Control and monitor air quality from anywhere with the MyDyson app,6 or hands-free with compatible voice services.7

Frequently asked questions
Does the LCD display stay on throughout the night?
If you're concerned by the brightness of your purifying fan heater's LCD display, consider enabling Night-time mode using your remote control or the MyDyson™ app. During operation, a small moon icon indicates that your purifier is on, but the main display turns off after 10 seconds to help avoid sleep disturbance.]
How do I know when my purifying fan heater is in auto mode?
If auto mode is enabled, AUTO will be illuminated on your purifying fan's LCD display. When your machine is purifying the air, AUTO will be in white. When the air in the room is purified, it will turn green and your purifying fan heater will remain idle until pollutant levels rise.
How long should my purifying fan be turned on for?
Your purifying fan's auto mode is designed to manage the air quality in your home without you having to operate the machine – so it's only on when it needs to be. If you or someone in your home suffer from allergies or respiratory illnesses, we particularly recommend using your machine's auto mode.
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 MyDyson™ app. The catalytic filter never needs replacing.]
Should I change the fan settings in different seasons?
Increasing airflow will create a cooling effect using purified air, so you may find it beneficial to change your purifying fan heater's speed settings as the temperature changes. For personal cooling in summer, use settings 4-10. In colder periods, enable diffused mode. It projects air through the back of the machine, to avoid unwanted cooling.
Should I keep my windows open or closed?
Your purifying fan heater works most efficiently in a sealed environment – opening the windows can allow more pollutants to enter the air in your home, which means your machine will take longer to work.
Where should I place my purifying fan heater?
Your purifying fan heater is engineered to purify single rooms, so you should use it where you spend the majority of your time at home. When placing the machine, make sure there is at least a few feet of clearance on all sides so that the air can circulate effectively.
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.
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). Gas capture rates vary.
3 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%.
4 In maximum setting. Tested for air projection, purification coverage in a 81m3 room and heating performance in a 35m3 room.
5 Whole machine tested by independent third-party laboratory Airmid (Ireland) in 28.5m3 test chamber pre-conditioned to 20±3C and RH 50±5%. Influenza A (H1N1) aerosolised in the test chamber and airborne concentration observed for the duration of 60 minutes under maximum Fan speed. Dyson Purifier achieved 99% efficacy but real life efficacy may differ depending on actual environment and Fan speed. Tested on Influenza A (H1N1) only.
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.
