Hassle-Free Manual Controls

With easy-to-use manual dial controls, the Air-O-Swiss U600 Ultrasonic Humidifier makes setup and operation a breeze. Use the manual control panel to:

• Set and Maintain Your Desired Humidity – Use the hygrostat dial to set your desired humidity level. Once your humidity level is reached, the humidifier will cycle on and off automatically to maintain your programmed level.


• Regulate Mist Output – Use the mist regulation dial to control the amount of moisture released from low output to high output.

Choice of Warm or Cool Mist Operation

Count on the Air-O-Swiss U600 Ultrasonic Humidifier to provide comfortable warm or cool humidified air in any room of your home. To operate as a cool mist humidifier, fill the water tank with clean, cold water while the humidifier is unplugged. After turning on, water passes down through the base of the humidifier and flows through the demineralization cartridge. After mineral deposits are removed, the water is transformed into a fine invisible mist and is distributed throughout your space.

When used as a warm mist humidifier, the Air-O-Swiss AOS U600 Humidifier uses a pre-heating function to heat the water before it is released as a soothing warm mist at 104 degrees F. Warm mist operation ensures that your heated room temperature does not drop significantly when the humidifier operates. Pre-heating also helps improve water quality maintenance.

Additional Features

The Air-O-Swiss Ultrasonic Humidifier U600 includes a number of additional features to help simplify operation.

• Continuous Operation – Instead of programming the humidifier to automatically maintain your humidity, you can operate the unit continuously to meet the needs of your environment.


• Demineralization Cartridge – The included demineralization cartridge removes mineral deposits from hard water that could lead to unhealthy white dust. The cartridge lasts up to 3 months and can be replaced with a new Air-O-Swiss Replacement Demineralization Cartridge or refilled with Air-O-Swiss Refill Granules.


• Hydro Stick – Treated with an antimicrobial coating, the Air-O-Swiss Hydro Stick helps curb mold and mildew growth inside the humidifier and ensures fresh humidification performance in between recommended cleanings.


• Titanium Membrane Housing – Heavy-duty titanium membrane housing ensures long-lasting use and guarantees fast dispersal of mist throughout your environment.
