Dyson Purify Humidify + Cool™ Auto React Air Purifier Fan

Dyson's latest PH3A machine purifies and hygienically humidifies a whole room* – removing 99.9% of bacteria in the water² with Dyson Ultraviolet Cleanse technology.

It has advanced sensing with three sensors to constantly monitor your air quality, automatically reacting to purify, maintain your target humidity and report results in real time.

Two layers of purification clean your air, with HEPA H13 and activated carbon to capture gases and 99.95% of pollutants as small as 0.1 microns.** And the whole purifier, not just the filtration system, is fully-sealed to HEPA H13 standard – so what goes inside, stays inside.

Only Dyson purifiers have Air Multiplier™ technology, to purify and humidify the whole room*. It generates powerful circulation, drawing pollutants from every corner into the filters and projecting purified, humidified air throughout the room.

The Dyson hassle-free Deep clean cycle thoroughly eliminates limescale throughout your machine's water system – at the touch of a button.

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.

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 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.

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.***

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.**

Remote control

*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.

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

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