The subtle water illumination makes the BONECO U200 a real eye-catcher - a unit for every home. The blue illumination can be switched on and off with the sliding switch on the backside of the main body. This handy and compact design fits anywhere and the cleaning is done quickly. Turning the U200 dial control clockwise switches the appliance on and at the same time regulates the mist output from low to high. The U200's high humidification output guarantees optimal humidification with a low energy consumption. The unit is also whisper-quiet, allowing for a restful sleep or an undisturbed working environment. The water level indicator clearly shows how much water is in the appliance. The appliance switches off automatically when the water tank is empty. The water level indicator illuminates red (red illumination cannot be switched off). Finally, scented aromatic substances, such as essential oils, can be added to the fragrance tray on the back of the BONECO U200 to disperse a pleasant aroma while it humidifies your room.
