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 outside8. On top of this, dry air from central heating and air conditioning can affect the air we breathe. Fortunately, there is a solution to both – all year round.

Why humidification matters

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

And purification too

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

Dyson purifier humidifiers are tested beyond the industry standard

Dyson test their 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.

Senses and reports, automatically

Three sensors constantly monitor your air. Dyson's unique algorithm diagnoses pollutants at a molecular level – reacting to purify and humidify before displaying live air quality in real-time reports. You can use the MyDysontm app to do this.

Captures pollutants with advanced HEPA filtration

A carbon filter removes gases such as benzene and HEPA filter captures 99.95% of particles as small as 0.1 microns.3

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. Cleansed water is then evaporated by the biostatic 3D air mesh, before hygienic, humidified air is projected throughout the room.5

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 Dyson’s product filtration efficiency at MPPS achieved 99.95% H13 HEPA level defined by EN1822, compared to the purifiers based on market data [from March 2020]. Product filtration efficiency tests conducted at IBR US within a chamber specified in ASTM F3150, under max mode and using particles challenged by DEHS oil according to EN1822.

3Tested for filtration efficiency at 0.1 microns (EN1822, ISO29463).

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 Tested for purification coverage in an 81m3 chamber. Tested for humidification coverage in a 41m³ chamber.

Security software updated for this machine will be supported until 31/12/31.
