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, this machine is engineered to purify and humidify single rooms, and works most efficiently in a sealed environment.
Senses and reports, automatically
Integrated sensors constantly analyze 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 filter captures 99.97% of particles 0.3 microns in size. An additional filter also removes odors and gases including VOCs.
Destroys formaldehyde, continuously.
Household items like wood flooring and fabric can release formaldehyde for years. The Dyson catalytic filter traps and breaks down formaldehyde molecules into water and CO2. And it never needs replacing.
Precisely detects formaldehyde
A lifetime solid-state sensor detectsformaldehyde molecules – 500 times smaller than 0.1 microns.
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 standard⁴, it's the whole machine. So what goes inside, stays inside.
Circulates purified humidified air
Dyson Air Multiplier™ technology mixes and circulates purified, humidified air throughout the room.
Cools you when needed
In warmer weather, a powerful stream of purified, humidified airflow can cool you down.⁸
Constantly monitors your air quality, automatically adjusting airflow to reach and maintain the most comfortable humidity level and react to pollution events.
An efficient water management system and a one gallon tank give you up to 36 hours⁶ of hygienic humidification without regular refilling.
Deep clean cycle
Activate the machine's monthly hassle-free Deep clean cycle at the touch of a button. It will guide you through the simple step-by-step process.
Simple filter changes
Built-in reminders show you when your combination filter needs changing. It's quick and easy to do.
Control and monitor air quality from anywhere using the MyDyson app.⁵
Control it hands-free with compatible voice services including Amazon Alexa, Siri and Google Assistant.⁵
Purifies using the quietest settings and a dimmed display. Sleep timer enables pre-set intervals of use, between 15 minutes and 9 hours.
Backward airflow mode
Diverts airflow through the back of the machine. To purify and humidify, without cooling you.
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.

Frequently asked questions
We've re-engineered our latest purifier humidifier to be fully-sealed to HEPA H13 standard.⁴ So what goes inside, stays inside. With a hassle-free Deep clean cycle that eliminates mineral build-up throughout your machine's water system.
The Dyson Purifier Humidify+Cool Formaldehyde™️ has all of the capabilities found in our Dyson Purifier Humidify+Cool™️ 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.
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.
Your Dyson Purifier 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. You can select your water hardness with the Dyson Link app. Running a Deep clean cycle helps to eliminate odors that occur through poor maintenance.
