Ultrasonic Humidifiers

Available in both cool and warm mist versions, ultrasonic humidifiers use high-frequency sound waves to vibrate a metal diaphragm until it reaches an ultrasonic frequency. This motion creates small water droplets that are thereby released into the air as a fine, moisturizing fog. Typically, ultrasonic units are the quietest of all humidifier types because they emit sound waves at a frequency higher than we can hear.
