DESC: This efficient Air-O-Swiss Ultrasonic humidifiier uses several cutting edge technologies to achieve an optimum quality of environmental control. High-frequency vibrations generate a micro-fine mist, while an Intelligent Temperature Compensation system (ICS) measures humidity relative to the room temperature and automatically adjusts the output to achieve an optimum balance dynamically as conditions change. The water is kept clean with three separate processes that make up the Microbial Protection System: ultrasonic technology, pre-heating, and Ionic Silver Stick. The latter makes use of the proven anti-microbial qualities of Silver, which has proven effective against more than 650 types of bacteria without any chemical additives.
