DESC: Humidification System This Digital Ultrasonic humidifier uses high-frequency vibrations to generate a micro-fine mist when blown into a room immediately evaporates. Choose the pre-heating function and mist exits the appliance at a pleasant 104 °F. «ITCTM» technology (Intelligent Temperature Compensation) monitors the temperature and automatically adjusts the output when conditions change. A replaceable demineralization (Ag+ Ionic Silver Technology) cartridge ensures water mist without lime scale or mineral residues, and the AIR-O-SWISS quad-band microbial protection system prevents microbial growth in the water base. This is particularly important when the humidifier is not used for some time with water remaining in the base.\n
