Abstract

An evaporative humidifier includes a top cover and a water reservoir tank removably mounted on top of a base platform. Several of the components of the humidifier contain a biocide for resisting the growth of bacteria and fungi on all surfaces of the components. The humidifier includes, in one embodiment, a pump assembly for moving water from the base platform to the top of an evaporator panel disposed in an air stream drawn through the humidifier. Alternatively, a paper wick is partially submerged in the pool of water in the base platform for drawing water up into the air stream by capillary action.
