Dyson, a company best known for its line of high-end vacuum cleaners, has just announced a new humidifier that's designed to kill bacteria in the air using what it calls "Ultraviolet Cleanse" technology.
The company points out that some ultrasonic humidifiers can actually spread bacteria through the air. Ultrasonic humidifiers create moisture though a metal diaphragm that moves at extremely high speeds. This creates water droplets, which are then dispersed through the air. If there's bacteria on said diaphragm, that will be transferred to the water, and thus blown into the room.
The solution, according to Dyson, is exposing the droplets of water to ultraviolet light, which it claims will kill 99.9 percent of the bacteria contained within the droplets. Ultraviolet germicidal irradiation is not a new method of killing germs, so it makes sense to see it applied here.
Outside of the bacteria removal, Dyson's new humidifier is promised to humidify a room of up to 172 square feet (16 sq m). It also has sensors that measure temperature and humidity, thus making sure it does not make a room too moist or warm for proper comfort. As with all ultrasonic humidifiers, Dyson is promising that its offering will be silent, with the ability to work for 18 hours on a single tank of water.
The Dyston Humidifier is coming in the fall of 2015 (Northern Hemisphere), though the company did not announce an exact release date. Pricing information was also not made available at the time of this writing.
