Abstract: A multi-layer filter material assembly. The assembly includes a filter medium which consists of a single sheet formed of fibers of a glass having a low coefficient of thermal expansion. The filter medium is supported on each side by at least one sheet of bonded synthetic fibers and a sheet of metallic wire mesh. The two sheets of metallic wire mesh form the two outermost layers and the entire assembly is formed into a pleated configuration.
