Improve the air quality inside your home
Pollution isn't just a problem outside. In fact, the average home can be up to five times more polluted than the air outside. On top of this, dry air from central heating and air conditioning can affect the air we breathe. Fortunately, we have a solution to both – all year round.

Why humidification matters
Our machine has in-built intelligence that can help with dry air by adding moisture automatically. This optimises humidity levels in the air by ejecting an invisible stream of evaporated water – with no mist.

And purification too
Many household items leak pollutants like pollen, dust, pet allergens, odours and smoke. Dyson purifiers sense and capture them, in advanced HEPA and carbon filters.

Powerful circulation to purify and humidify the whole room⁶
Dyson purifiers draw pollutants, such as pollen, dust, allergens and smoke, from every corner of the room and Air Multiplier™ technology projects purified, humidified air throughout the room.⁶
Dyson purifier humidifiers are tested beyond the industry standard
We test our purifier humidifiers 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.
Industry-standard test chamber – only 28.5m³
Dyson POLAR test chamber - 81m³

Senses and reports, automatically
Three sensors constantly monitor your air. Our unique algorithm diagnoses pollutants at a molecular level – reacting to purify and humidify before displaying live air quality in real-time reports.

Only a Dyson is fully sealed to HEPA H13 standard⁴
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 humidifier.⁴ So what goes inside, stays inside.
Destroys potentially harmful bacteria
Dyson Ultraviolet Cleanse technology exposes every drop of water to a powerful λ275nm UV light. This kills 99.9% of bacteria in the water.² Cleansed water is then evaporated by the biostatic 3D air mesh, before hygienic, humidified air is projected throughout the room.⁶
To humidify your environment, hygienically
Central heating and air conditioning units can contribute to dry air developing in the home, which can cause dehydration. The Dyson purifying humidifying fan automatically maintains the target level of moisture in your air with an invisible stream of evaporated water, and no mist – for a more comfortable environment.
Hassle-free Deep clean cycle
The Dyson hassle-free Deep clean cycle thoroughly removes mineral build-up throughout your machine's water system. At the touch of a button, the cycle activates and guides you through a simple step-by-step process.
