    Helpful air humidifying tips

    Dyson purifier humidifiers can achieve desired humidity either automatically or manually in a single room. In Auto mode, set it and forget it.

    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 to HEPA H13 standard.⁵ With a hassle-free Deep clean cycle that  eliminates mineral build-up throughout your machine's water system.

    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. Running a Deep clean cycle helps to eliminate odors that occur through poor maintenance.

    Do Dyson purifiers capture wildfire smoke?
