Abstract
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.
