Compare Ultrasonic Humidifiers

Ultrasonic humidifiers use high-frequency vibrations to generate a micro-fine cool or warm mist. This micro-fine mist is blown into the room where it immediately evaporates to create a comfortable environment. Ultrasonic humidifiers are virtually silent and make for an excellent choice in the bedroom. Our Air-O-Swiss humidifiers are best in class and meets all your needs when it comes to efficient humidification. The pureguardian™ humidifiers are our top value ultrasonic humidifiers that are easy to clean and maintain.
