Dyson launches new humidifier technology. Existing humidifiers can harbour nasty bacteria which they then circulate around the home. The Dyson humidifier uses Air Multiplier™ technology for even distribution and Dyson’s own Ultraviolet cleansing technology to kill 99.9% of bacteria in water. It projects clean, hydrated air around the room evenly and quietly. Helping you keep healthy in the winter, and doubling up as a fan to keep you cool in the summer.
