Boneco Air-O-Swiss Cool-Mist Ultrasonic Humidifier

Used only slightly! Never used with essential oils! "This energy-efficient ultrasonic humidifier system uses high-frequency vibrations to turn water into a micro-fine mist, which is then blown into the room where it evaporates immediately. A built-in output regulator ensures that the humidifier properly humidifies the room in which it is used. Cool mist. Includes fragrance container.
