The tower-design lets this Ultrasonic Humidifier function gracefully and finds space anywhere. All functions are controlled by the multi functional digital display. The integrated hygrostat displays the current air humidity and allows a manual regulation. If a constant relative humidity is desired to be adjusted to your room temperature, this is ensured by Auto-Mist Technology (AUTO MODE) - and SLEEP-MODE. The duration of operation can be limited by the timer. The reminder notices for the cleaning and water filling ensures an optimal state of the device. The Humidifier offers the choice of warm or cool humidification that flows out from the double jet nozzle.Thanks to effective high-frequency technology, the water is converted into a micro-fine mist and given off to the indoor air by a fan. The integrated demineralisation cartridge provides water mist without limescale. The included Hydro Cell ensures optimal water quality. The low-noise appliances have a very high level of humidification, which can be individually regulated by an output control. As the room temperature can fall slightly as the mist evaporates, this BONECO Ultrasonic Humidifier can be set to give off cool or warm humidification at the press of a button.
