The present invention relates to a producing method of a laminated filter that carries out a corrugating operation and an adhering operation of filter media in the same step. A corrugation forming apparatus () sandwiches first and second filter media () in their superposed state, and heats and presses the first and second filter media () at the softening temperature of the second filter medium () to corrugate the filter media (), and thermally adheres the first and second filter media () to each other. With this, it is possible to carry out the corrugating operation and the adhering operation of the first and second filter media () in the same step.

Producing method of laminated filter

A filter element for an air cleaner including a filter medium which has a plurality of basic filter units and is integrally formed of a porous sintered material produced by sintering powdered synthetic resin.

Filter element for air cleaner

A resin-made air cleaner includes a hollow resin-made housing, a tubular element accommodated in the housing, a tubular projection, a gasket fitted around the tubular projection, and disposed between the tubular element and the tubular projection, a stopper for inhibiting the gasket from moving. The tubular projection is disposed on at least one of opposite end surfaces of the housing so as to project toward the inside of the housing. The stopper is disposed on the projection and/or the opposite end surfaces of the housing, on which the projection is disposed. This arrangement not only enables the increase of the resin content of the air cleaner, but also inhibits the gasket from coming off from the projection when the element is disassembled.
