ABSTRACT:
A humidifier pad made of a plurality of laminated sheets connected together in a stack. Each of the sheets is made of a two layer laminate material made of a first layer of a rigidifying material, such as aluminum, and a second layer made of an absorbent layer, such as paper. The layers of each of the sheets are first laminated together, and then each sheet is slit and expanded in a conventional manner. Subsequently, each sheet is bonded to a next adjacent sheet to form a pad.
