Air-O-Swiss AOS 7144 Digital Warm & Cool Mist Ultrasonic Humidifier

AOS7144 Digital Warm & Cool Mist Ultrasonic HumidifierThe AOS7144 combines compact design with powerful performance...

A new entry into the Air-O-Swiss product line in Fall 2008, the AOS7144 uses many of the great features of the popular AOS7142.  The key difference is that the AOS7144 is designed for use in smaller rooms, so the unit takes up less space than the AOS7142.

As with all of our Ultrasonic humidifiers, this uses high-frequency vibrations to generate a micro-fine mist.  The mist quickly evaporates when it is released into the room.  Choose the pre-heating function and warm mist exits the humidifier at a pleasant 104 °F.

Intelligent Temperature Compensation (ITC) 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, and the AIR-O-SWISS quad-band microbial protection system prevents microbial growth in the water base.
