1. A filter holding frame, comprising:
- a plurality of walls coupled to form a rectangular ring;
a flange extending inward from a back edge of each wall; and
a first flexible retaining member coupled to at least one of the walls and positioned in a parallel spaced-apart relation proximate to one of the flanges, wherein a surface of the flange and a surface of the first flexible retaining member define a filter receiving pocket for retaining a filter element and the first flexible retaining member is repositionable on the wall to select a depth of the filter receiving pocket.

Abstract
Embodiments of the invention generally provide a holding frame having at least one rigid retainer and/or flexible retainers. The holding frame assembly is typically mounted in a housing of an air handler or other air moving conduit. The rigid retainer(s) and flexible retainer(s) are coupled to the holding frame assembly to define filter retaining pockets that retain a final filter within the holding frame assembly without use of clips and other fastening mechanisms.
