Our latest machine purifies and hygienically humidifies a whole room1 – 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.4 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.1 It generates powerful circulation, drawing pollutants from every corner into the filters and projecting purified, humidified air throughout the room.

Key Features

Pioneering Dyson technology

Our latest purifier humidifier was engineered to deal with pollution and dry air, using multiple advanced technologies.

Control your airflow

Jet axis control allows two oscillators to guide airflow through apertures at a 90° range.

Senses pollutants and allergens
Detects particles and VOCs in the air.

Captures gases and odours
An activated carbon filter captures gases such as benzene and NO2 5

Removes allergens and pollutants

Purifies by removing 99.95% of ultrafine particles2

Prevents bacteria growth
Cleansed water is drawn through the evaporator’s 3D air mesh – with biostatic silver strands to help prevent bacteria growth.

Remote control
Control with remote. Not app compatible.

Hygienically humidifies

Dyson Ultraviolet Cleanse technology hygienically removes 99.9% of bacteria in the water2.


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 outside3. 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.
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

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.

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.2

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.4

Remote control
Curved and magnetised to store neatly on top of the machine.
Control with remote. Not app compatible.


Frequently asked questions
How does a purifier humidifier work?
The Dyson purifier humidifier senses and captures pollutants and measures the level of moisture in the air – automatically. Then, it projects purified and hygienically humidified air around the whole room4, cooling you when needed.
Should I use a purifier humidifier all year round?
Yes, to get the best results, a purifier humidifier should be used all year round. To help combat dry air from central heating and air conditioning, and capture pollutants such as dust, pollen, smoke, odours and pet allergens. You can also use the purifier humidifier when sleeping, on night mode.
What is new about the Dyson purifier humidifier and how is it different to other purifier humidifiers?
We've engineered our latest purifier humidifier to be fully sealed to HEPA standard.1 With a hassle-free Deep clean cycle that removes limescale throughout your machine's water system.
Where should I place the purifier humidifier in my room?
Your Dyson Purify Humidify + Cool™ Auto React is engineered to purify and humidify single rooms, so you should use it where you spend the majority of your time at home. When placing the machine, make sure there's at least a few feet of clearance on all sides, so that the air can circulate effectively. Close doors and windows and place away from air vents.
Can I switch off humidification?
Yes. The machine works as a purifier humidifier, or just a purifying fan.
How often should I run a Deep clean cycle?
This depends on the water hardness where you live. The machine prompts you to run the cycle once a month in hard water areas. It prompts you less often in softer water areas.

Caveat
1 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.
2 Tested for filtration efficiency at 0.1 microns (EN1822, ISO29463).

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




Technology


Senses and reports automatically

Integrated sensors constantly analyse your air, while our unique algorithm cross-checks data every second. It diagnoses pollutants at a molecular level, displaying live results on the LCD.


Captures gases and ultrafine particles

The HEPA H13 filter captures 99.95% of particles as small as 0.1 microns.¹ A layer of activated carbon also removes odours and gases including VOCs.²


Destroys potentially harmful bacteria

Dyson Ultraviolet Cleanse technology exposes every drop of water to a powerful λ275nm UV light, to hygienically humidify.


Fully sealed to HEPA H13

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 humidifer.⁵
