The Humidifier kills 99% of airborne bacteria using UV cleanse technology and creates a clean, humidified draft that will quickly improve the air quality in a 16 sq. meter room. It works by drawing air through inlets in its base and over a thermostat and humidistat which accurately monitor the room’s temperature. It is also the first humidifier to be awarded the ‘quiet mark’ by the Noise Abatement Society.
