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.
Claims13
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.

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;
- a plurality of engagement features coupled to a first wall of the plurality of walls, wherein the engagement features are spaced at pre-determined distances from the back flanges of the walls;
- at least one flexible retaining member coupled to the first wall by a first engagement feature of the plurality of engagement features at a first position selected to define a filter receiving pocket for retaining a filter element;
- and
- a rigid retaining member coupled to at least one of the walls not having the first flexible retaining member coupled thereto, wherein the rigid retaining member is disposed in a parallel spaced-apart relation to one of the flanges to define the filter receiving pocket.
