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.
Precisely detects formaldehyde
A lifetime solid-state sensor detects formaldehyde molecules – 500 times smaller than 0.1 microns.
-
Captures gases and particles
Captures 99.97% of particles as small as 0.3 microns. Combined with activated carbon, it also removes odours and gases including VOCs.³
Destroys potentially harmful bacteria
Dyson Ultraviolet Cleanse technology exposes every drop of water to a powerful λ275nm UV light, to hygienically humidify.⁴
-
Destroys formaldehyde, continuously
A catalytic filter continuously traps and breaks down formaldehyde molecules into water and CO₂. And it never needs replacing.¹
Dyson’s latest purifiers are fully sealed to HEPA H13
To prevent pollutants leaking back into the air, it's not just the filter that's sealed to HEPA standard, it's the whole purifier humidifer.

Frequently asked questions
What is new about the Dyson purifier humidifier and how is it different to other purifier humidifiers?
We've re-engineered our latest purifier humidifier to be fully sealed - what goes inside, stays inside. With a hassle-free Deep clean cycle that removes mineral build-up throughout your machine's water system.
What is different about the Dyson Formaldehyde range?
The Dyson Purifier Humidify+Cool Formaldehyde has all of the capabilities found in our advanced purification products but goes a step further to detect and destroy formaldehyde.¹ An added solid-state sensor precisely detects formaldehyde, while our catalytic filter breaks it down into two safer molecules – carbon dioxide and water.
What is formaldehyde and what are common sources of it?
Formaldehyde is a polluting gas formed of carbon, hydrogen and oxygen that is commonly found in homes. Common sources of formaldehyde could be: paint and varnishes, air fresheners, mattresses, furniture, household cleaners, carpets, particleboard and plywood, electronics, dryer sheets, nail polish remover, moth balls, toys, fireplaces and wood burning stoves.
Where should I place the purifier humidifier in my room?
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.
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. You can select your water hardness with the MyDyson app.⁵

* Dyson purifiers were challenged with airborne influenza A (H1N1 virus), MS2 bacteriophage at an independent lab, using a 30 m3 chamber. After 60 minutes at maximum fan speed, the airborne concentration in the chamber was reduced up to 99.9 %. Real-life efficacy may vary.
** Dyson purifiers were challenged with airborne SARS-CoV-2 (the virus that causes COVID-19) at an independent lab, using a 0.37 m3 chamber for 90 seconds. Dyson Purifiers were also challenged with Phi-6 bacteriophage (a surrogate to test SARS-CoV-2) at an independent lab, using a 30 m3 chamber. After 90 minutes at maximum fan speed, the airborne concentration in the chamber was reduced by 99.9 %. Real-life efficacy may vary.
