Product DescriptionThis 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 104F ITC technology 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. The humidity output can be cool or warm as required. In winter, warm mist prevents a drop in room temperature; in summer, cool mist provides pleasant freshness. The digital display allows the indoor climate to be comfortably controlled. Thanks to Auto-Mist Technology (AUTO MODE), the humidification control can be matched fully automatically to the temperature. The mist can be distributed in the room in two directions using the double jet nozzle.
