Both professional reviewers and owners praise the Air-O-Swiss Ultrasonic 7135 humidifier for its ultra-quiet operation, good moisture output and advanced features. It outputs up to 3.5 gallons per day and is rated for room sizes up to 650 square feet. This model produces either warm or cool mist and comes with a hygrometer and digital LCD display that allows users to preset and control the humidity. A hydro stick keeps the water fresh, and a demineralization cartridge helps minimize white dust. However, some users find the cartridge ineffective and recommend using distilled water to eliminate the problem. Some owners also complain that the humidity readings are inaccurate, the tank is cumbersome to refill and the humidifier has a tendency to develop leaks. We found somewhat better reviews for the more expensive Air-O-Swiss Ultrasonic 7144  (*Est. $200) , which has similar features and a sleek modern design.

The most useful review we found for the Air-O-Swiss Ultrasonic 7135 humidifier comes from ConsumerReports.org, which includes this model in its latest roundup of humidifiers. The humidifier also receives a professional evaluation from AllergyBuyersClub.com, which provides a comparative rating as well as short appraisals of its basic features, cleaning needs and parts.
