Helpful tips about humidifying your air
Dyson purifier humidifiers let you achieve your desired humidity either automatically or manually. In Auto mode, just set it and forget it. In manual mode, the LCD indicates if you need to increase airflow – which may help you reach your target quicker. And remember, keeping your machine away from drafts and turning down your home’s heating or AC units can also improve performance.
Technology
Senses and reports, automatically
Three sensors constantly monitor your air – diagnosing pollutants at a molecular level and displaying live air quality in real-time reports.
Captures gases and ultrafine particles
Captures 99.95% of particles as small as 0.1 microns.³ Combined with activated carbon, it also removes odours and gases including VOCs.⁶
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 standard⁵
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
Features
Circulates purified humidified air
Dyson Air Multiplier™ technology mixes and circulates purified, humidified air throughout the room.
Cools you
In warmer weather, a powerful stream of purified, humidified airflow can cool you down.
Auto mode
Constantly monitors your air quality, automatically adjusting airflow to reach and maintain the most comfortable humidity level.
Continuous humidification
An efficient water management system and a one gallon tank give you up to 36 hours* of hygienic humidification without regular refilling.
Night mode
Purifies using the quietest settings and a dimmed display. Sleep timer enables pre-set intervals of use, between 15 minutes and 9 hours.
Diffused mode
Diverts airflow through the back of the machine. To purify and humidify, without cooling you.
Breeze mode
Unique algorithms vary the airflow to mimic a cooling, refreshing breeze.
Jet Axis control
Two oscillators guide the airflow – projecting separately, or in unison, so you can choose different airflow modes.
Deep clean cycle

Frequently asked questions
We've re-engineered our latest purifier humidifier to be fully sealed to HEPA H13 standard.⁵ With a hassle-free Deep clean cycle that eliminates mineral build-up throughout your machine's water system.
Your Dyson Pure Humidify+Cool™ 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.
Yes. The machine works as a purifier humidifier, or just a purifying fan.
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. Running a Deep clean cycle helps to eliminate odours that occur through poor maintenance.
- 1 Filter efficiency tested at 0.1 microns (EN1822)
- 2 Tested for purification coverage in an 81m³ chamber. Tested for humidification coverage in a 41m³ chamber.
- 3 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 oil according to EN1822.
- 4 We challenged our purifier with airborne influenza A (H1N1 virus) at an independent lab. After 60 minutes at maximum fan speed, the airborne concentration in the chamber was reduced by 99%. Real-life efficacy may vary.
- 5 Gas capture rates vary
- 6 Based on fan speed 1
- 5 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%.
