ABSTRACT:
A humidifier pad for use in humidifiers suitable for adding moisture to the air circulated by a forced air furnace is described together with its method of manufacture. A slab of open-cell foam is stamped using a reciprocating cutter to form humidifier pads which are seamless. These seamless pads are adapted to be fitted onto the cylindrical support frame of the humidifier and the pad is especially useful in a combination with a type of frame which is collapsible cylindrical and which facilitates removal and replacement of the pad.
