Abstract
A room humidifier is disclosed having a floating wick assembly having wick elements, the wick assembly floating on a water supply thereby to maintain a constant water depth and evaporative area on the wick element as the water level within the humidifier rises and falls. The wick element is formed of a web of non-woven, fibrous material (e.g., a paper-like material) which draws water by capillary action from the reservoir onto the evaporative area of the wicking element from when water is evaporated into the air drawn through the wicking element by a fan for discharge into the room. The wick element may readily be removed from the wick assembly for cleaning or replacement.
