ANTON Ultrasonic Humidifier - BerrySmall in stature, but huge in performance - that"s Anton! Even if it is easily overlooked because of its diminutive size, rooms of up to 250 sq ft pose no challenge to Anton. He is an ultrasonic humidifier 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, Anton will not leave the white powdery film produced by other humidifiers and keep the water clean and pure. Elegance and easy operation are maintained by control buttons located out of sight on the underside. Easy readability of the water level is indicated by the stylishly designed LED indicator lights which switch from blue to red when the tank is empty.Features: Night ModeAutomatic Shut-OffPerfume DispenserRoom size up to 250 sq ftOutput max 1 gallon per dayIndefinite variable output level18 Watt
