Low-Hassle Automatic Humidification

Unlike conventional portable humidifiers, the Air-O-Swiss 7147 Ultrasonic Warm & Cool Mist Humidifier boasts a variety of automated features to help simplify operation and make it hassle-free. These features include:

• Automatic Humidity Control – Using the built-in hygrostat, set your desired humidity from 30% to 80%. The humidifier will use Intelligent Temperature Compensation technology to automatically regulate mist output to maintain your selected humidity level.

Control panel brightness is also dimmed.


• Refill Indicator – This red indicator icon automatically illuminates when it's time to refill the humidifier. You can also easily keep an eye on the water level with the transparent tank.


• Clean Indicator – A special clean indicator illuminates to let you know that it's time to clean the humidifier. For your convenience, this indicator activates every two weeks.

Choice of Warm or Cool Mist Humidification

Count on the Air-O-Swiss AOS 7147 Humidifier to provide comfortable humidified air in any room of your home during the dry winter months. A lack of moisture in the air can irritate your allergy and asthma conditions and cause chapped lips, red eyes, and itchy skin. Additionally, dry winter air can damage your home furnishings, valuables, and interior infrastructure. The Air-O-Swiss 7147 Ultrasonic Humidifier reverses the effects of cold wintry air using ordinary tap water.

This tabletop humidifier offers a choice of warm or cool mist operation to suit your preference. 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 micro-fine mist and is distributed throughout your space.

When used as a warm mist humidifier, the Air-O-Swiss AOS 7147 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.
