Humidification System
This 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 °F. A replaceable demineralization cartridge (Ag+ Ionic Silver Technology) ensures water mist without lime scale or mineral residues, and the AIR-O-SWISS quad-band water protection system inhibits microbial growth in the water of your humidifier. This is particularly important when the humidifier is not used for some time with water remaining in the base.
