FILTERS, SUPPORTS FOR FILTERS, AND METHODS OF PRODUCING FILTERS HAVING SUPPORTS

摘要

A filter assembly includes a filter media comprising at least one of wool, viscose, and thermoplastic polymer material; a supporting layer proximate to the filter media comprising at least one of a mesh, a frame, and a thin board; and a retaining member configured to engage the filter media and the supporting layer to hold the filter media and supporting layer together. A method of manufacturing a filter assembly includes carding fibers into a web to form a filter media comprising at least one of wool, viscose, and thermoplastic polymer material; coupling the filter media with a supporting layer comprising at least one of a mesh, a frame, and a thin board, and trimming or punching the coupled filter media and supporting layer to a predetermined size.
