Air-O-Swiss® Ultrasonic Humidifier AOS U600

Ultrasonic humidifier features efficient air humidification technology that uses high-frequency vibrations to generate micro-fine mist. It includes a replaceable demineralization cartridge that guarantees water mist without mineral residue. When pre-heating function is on, mist exits the humidifier at 104° Fahrenheit, and the included Hydro Stick keeps the humidifier clean and fresh longer. You can also choose cool humidification. Humidifier includes hygrostat and mist output control for complete humidification and provides ultra-quiet operation. With a sleek design, humidifier features automatic shut-off with empty indicator and transparent water tank. With an industrial strength titanium membrane surface, fast dispersion of the mist into the air is guaranteed. Unit humidifies the air in rooms up to 650 square feet; output up to 3 1/2 gallons.
