Dyson Humidifier Uses Ultraviolet, Ultrasonic Tech

The company has worked to engineer an efficient product which sterilizes its own water

A new kind of quiet, effective, and hygienic humidifier is poised to enter to U.S. market. In just one year’s time, miserably dry winter interior spaces will go up against a new champion, the exhaustively engineered product of a (knighted) British design whiz.


Dyson, a company known for its innovative designs and really-darned-effective (if expensive) fans and vacuums, has entered the humidifier game. Soon to be available in Japan, the product will take advantage of a three-pronged system to distribute and humidify air evenly and hygienically.


“Humidifiers are sometimes seen as a way to combat allergies and the symptoms of colds and the flu – but in reality many can do quite the opposite,” founder Sir James Dyson tells Wired. “The majority are a breeding ground for nasty germs, which are then distributed around your home.”


The Dyson humidifier sets itself apart, its engineers explain, by using three separate technologies: ultrasonic to humidify the air, with a piezoelectric transducer in the machine’s base vibrating up to 1.7 million times a second, breaking water down into microscopic particles; ultraviolet tech, which Dyson claims will kill 99.9 percent of bacteria by double-exposing every drop of water to ultraviolet light, Wired explains; and Dyson’s “Air Multiplier” technology, used to distribute the humidified air evenly.


The Air Multiplier technology — which replaced fan blade systems in Dyson products five years ago — uses an aerodynamic design to propel a low volume of air into a pretty powerful wind; for their first humidifier, Dyson developers incorporated water into the same technology in order to hydrate air rapidly and evenly. “We’ve never tied ourselves down to a single technology,” says Rob Green, a senior design engineer at Dyson, to Wired. “We’re always looking at where we can use the technology to solve different problems—it’s always been about finding a problem and solving it.”


Dyson reports that the company spent more than $60.4 million to develop its new humidifier, a process which involved fabricating 643 prototypes before the final model was chosen. The resulting product has a three-liter water tank (enough for 18 hours of humidifying action), can be set to run for up to nine hours, and can be used as a regular fan when needed. It’s scheduled to be released in the U.S. next fall.
