Air O Swiss Ultrasonic Humidifier Consumer Reviews

Reviewers gave this ultrasonic humidifier three stars. Many people loved the design and quiet operation. A lot of people complained it didn’t work after a few weeks or months. It does come with a demineralization cartridge, but doesn’t come with a Ionic Silver Stick for water bacteria control. You can buy it separately.

Ultrasonic Humidifiers General Product Information- Ultrasonic cool mist humidifiers can leave a white dust on surfaces. Air O Swiss offers a replaceable bacteria inhibiting demineralization cartridge which eliminates the white dust.

Ultrasonic humidifiers are virtually silent, even on high. The option of a warm mist humidifier is nice for the winter when you don’t want drafts of humidified cold air. The stated sq. ft. of optimal humidification is generally on the high side, so opt for an ultrasonic humidifier that states it will humidify an area slightly larger than what you need.

AOS recommends accessories with ultrasonic humidifiers. The ionic silver stick which lasts one year, cost $30. The eco friendly cleaner and descaler $7. The demineralization cartridge for eliminating white dust, cost $13 and lasts 2-3 months. Air O Swiss humidifiers also have antimicrobial protection on the base to reduce growth of mold, bacteria.
