13. A method of manufacturing an air filter, comprising:
-
providing an air filter section comprising a filter media and support structures attached to opposite, pleated sides of the filter media, the support structures each having a center portion and sidewalls positioned on opposite sides of the center portion; providing a frame assembly having a plurality of segments, each of the segments having a center portion and sidewalls positioned on opposite sides of the center portion; positioning the air filter section so that a first side of the air filter section is located above a first frame segment; moving the air filter section into a framing form so that the first side of the air filter section contacts the first frame segment; moving a second frame segment into contact with a second side of the air filter section and moving a third frame segment into contact with a third side of the air filter section, the second and third frame segments attached to opposite ends of the first frame segment, the movement of the second and third frame segments caused by the movement of the air filter section into the framing form; moving a fourth frame segment into contact with a fourth side of the air filter section; and attaching sidewalls of the air filter section support structures to sidewalls of corresponding frame segments to form a hollow channel between the support structure and the corresponding frame segment along the pleated sides of the filter media. - View Dependent Claims (14, 15, 16)

17. A method of attaching a frame to an air filter, comprising:
-
providing a filter slug comprising a filter media and reinforcing structures attached to opposite sides of the filter media, the support structures each having a center portion and sidewalls positioned on opposite sides of the center portion; providing an unassembled frame having a plurality of segments, each of the segments having a center portion and sidewalls positioned on opposite sides of the center portion; positioning a first frame segment between a first side of the filter slug and a frame form; moving the filter slug into contact with the first frame segment and into the framing form; rotating second and third frame segments into contact with second and third sides of the frame slug, the rotation of the frame segments caused by the movement of the filter slug and frame into the framing form; rotating a fourth frame segment into contact with a fourth side of the filter slug; and permanently bonding the sidewalls of the filter slug reinforcing structures to the sidewalls of corresponding frame segments to form a hollow channel between the reinforcing structure and the corresponding frame segment. - View Dependent Claims (18)
