This efficient air humidification technology uses high-frequency vibration to generate a micro-fine mist. The unique aspect of this humidifier is the Intelligent Temperature Compensation (ICS) system that measures humidity in relation to room temperature and automatically takes corrective action when conditions change.

The Tri-band Microbial Protection System (ultrasonic technology, pre-heating, and Ionic Silver Stick) keeps the water clean. The cornerstone of this system is the high-tech Ionic Silver Stick (ISS), which makes use of the proven anti-microbial qualities of silver. Silver is effective against more than 650 types of bacteria, requiring no chemical additives.

When operated with the pre-heating function, the water is heated to 176°F before it enters the nebulizer chamber. The mist exits the appliance at a comfortable temperature of 104°F. This has the advantage that the room temperature will not fall, and additionally the water will be kept cleaner. A replaceable demineralization cartridge ensures a hygienic, pure water mist, without lime scale or mineral residues.
