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.
