Abstract

See full text

A three-dimensional filter includes a filter frame having a three-dimensional skeletal structure with a filter media connected to the skeletal structure. The filters are nestable. The skeletal structure may be trimmed and provided with walls to create standard sized filters. Methods for making the three-dimensional filter include injection molding of the skeletal structure onto the filter media, injection molding the filter media and the filter frame together in a single molding process, thermoforming a molded or extruded skeletal structure and the filter media, and needle punching a molded or extruded skeletal structure to create filter media within the skeletal structure.
