Abstract
A frame for holding an evaporative pad in the base of a humidifier includes side walls, base and a top that define an evaporative pad holding chamber. Each of the side walls, base and top is provided with a flange that extends inwardly toward the opening and is engageable with a lip on the base to form an air seal. The flange is provided with a rib portion that extends outwardly away from the pad chamber and is dimensioned so as to create a gap between the rib and any adjacent base surface in order to inhibit the migration of mineral deposits from the pad to the base.
