AIR-O-SWISS Digital Humidifiers
AIR-O-SWISS Near-Silent Digital Humidifiers (also known as Near-Silent Ultrasonic Humidifiers) are the quietest humidifiers on the market, using a high quality titanium transducer surface and adjustable high-frequency vibrations to turn water into a micro-fine mist. The titanium transducer surface is much stronger than ordinary metals, resists rust, lasts longer and requires less cleaning than other ultrasonic humidifiers. AIR-O-SWISS Ultrasonic Humidifiers are ideal for small to medium sized rooms, and are the top of the line choice when looking for the quietest and best quality room humidifiers.
All models listed below offer a digital humidistat and display and will provide identical performance with a maximum output of 3.5 gallons a day. This is the highest output that can be obtained from a near-silent, high quality humidifier.
