A cleaner, more comfortable environment

The Dyson purifier humidifier is engineered to help improve your air quality. Its activated carbon filter removes gases and its HEPA H13 filter captures 99.95% of particles as small as 0.1 microns.³ Air Multiplier™ technology then projects purified, humidified air throughout the room² – cooling you when required.

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.
