A humidifier is provided of the type which has a water tank or reservoir for holding tap water. Common tap water frequently is "hard" due to dissolved minerals which result in the humidifier emitting a fine dust when such water is used. By affixing electroplated electrodes to the interior of the tank minerals such as calcium carbonate can precipitate on the surface of the cathodes. Temporarily reversing the polarity of the electrodes will cause the calcium carbonate to be dislodged from the electrodes and fall to the bottom of the reservoir where it can be removed.

[ What is claimed is:] [1.] A room humidifier which provides moisture to the air having substantially reduced levels of calcium carbonate which comprises:(a) a reservoir for containing water having an inlet and an outlet;(b) a chamber having an inlet, adapted to communicate with said reservoir outlet so as to receive water therefrom;(c) an ultrasonic transducer for atomizing the water in said chamber and operatively connected thereto;(d) means for permitting the atomized water to pass from the humidifier to ambient air;(e) means for removing dissolved calcium carbonate from substantially all the water placed in said reservoir, by depositing the calcium carbonate on a surface by electroplating means, said electroplating means including: a cathode positioned within and connected to said reservoir, said cathode being the surface upon which the calcium ion is deposited, and an anode positioned within and connected to said reservoir, and means for providing a direct current to said anode and cathode; and(f) dividing means for dividing said reservoir into an upper portion and a lower portion; said reservoir outlet, cathode and anode being located in the lower reservoir portion, and said dividing means being positioned above said cathode and anode; said dividing means having an orifice for permitting water to flow from said upper reservoir portion to said lower reservoir portion, the dividing means orifice located to ensure that the water flows from said dividing means orifice through said cathode and anode to said reservoir outlet.
