Abstract
A humidifier including a housing defining an air inlet, an air outlet, an air flow path between the inlet and outlet and a liquid reservoir; a blower system for producing air flow between the inlet and the outlet; and a retainer removably mounted in the housing and shaped and arranged to support a liquid absorbent evaporator pad in the air flow path. Also included is an ejector mechanism movable relative to the retainer and operable to eject the evaporator pad from the retainer means. The ejector mechanism simplifies replacement of a dirt clogged evaporator pad.
