Breathe cleaner air at every moment
Many indoor activities and household products release invisible pollutants. Dyson air purifiers have been engineered to remove airborne particles – so you can breathe cleaner air.
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.
Common household pollutants
Painting, varnishes and printers
Benzene and VOCs
Traffic, building materials and furniture
Road traffic, tobacco and fuel-burning heaters
Fumes and cooking
Pollen and allergens
Only a Dyson works like a Dyson
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 the 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
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.3
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.
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.
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
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 gases5 and 99.95% of particles as small as 0.1 microns.2 Our catalytic filter continuously destroys formaldehyde1.
The purifier is sealed to HEPA standard4, removing 99.95% of particles as small as 0.1 microns.2
To prevent pollutants leaking back into the air, it's not just the filter that's sealed to HEPA H13 standard,4 it's the whole purifier. So what goes inside, stays inside.
Dyson purifiers create a powerful stream of purified airflow to cool you in warm weather. Lighter sleepers can enjoy Night mode that monitors and purifies using the quietest setting and dimmed display.
Warms you in winter
With long-range projection, it’s quick to heat the whole room evenly.1 Intelligent thermostat control maintains your preferred room climate.
Diffused mode. Purifies without cooling you.
Airflow is diverted through the back of the machine, maintaining effective purification.
For lighter sleepers, it monitors and purifies using the quietest settings along with a dimmed display.
Easy filter care
The catalytic filter doesn't need replacing. And when you need a new HEPA+Carbon filter, the Dyson Link app6 lets you know.
