Air-O-Swiss AOS 7145 Cool Mist Ultrasonic Humidifier

AOS7145 Cool Mist Ultrasonic HumidifierThe AOS7145 delivers cool mist in a stylish, compact package...

A new entry into the Air-O-Swiss product line in Fall 2008, the AOS7145 replaces the AOS7131 as an affordable, high-performance cool mist ultrasonic humidifier.

As with all of our Ultrasonic humidifiers, this unit uses high-frequency vibrations to generate a micro-fine mist.  The mist quickly evaporates when it is released into the room.

A replaceable (or refillable) demineralization (Ag+ Ionic Silver Technology) cartridge ensures water mist without lime scale or mineral residues, and the AIR-O-SWISS tri-band microbial protection system prevents microbial growth in the water base.
