Rooms of up to 250 square feet pose no challenge for this humidifier, which is small in stature, but huge in performance. Made of resistant materials and even capable of perfectly distributing the fragrance of your preferred scented oil throughout the room. Equipped with an anti-calcium cartridge and ionic silver cube, it keeps the water clean and pure and will not leave the white powdery film produced by other humidifiers. Elegance and easy operation are maintained by control buttons located out of sight on the underside. The water level is indicated by the stylishly designed LED indicator lights, which switch from blue to red when the tank is empty.
