Air-O-Swiss Refurbished 7133 Ultrasonic Humidifier - Warm and Cool Mist
This refurbished ultrasonic humidifier uses high-frequency vibrations to turn water into a micro-fine mist. The AOS 7133 Ultrasonic Humidifier gives you the option to disperse either cool or warm mist; send a cool mist into the room or choose the pre-heating function and dispense mist at a comfortable 104-DegreeF. A replaceable demineralization cartridge (Ag+ Ionic Silver Technology) ensures water mist without lime scale or mineral residues. The included Hydro Cell keeps the humidifier clean and fresh longer.
