Filter Frame Adapter

A filter frame adapter extending from a first end to a second end, the filter frame adapter configured to be releasably coupled to a filter having media and a border flange extending outwardly from the media, the filter frame adapter comprising:

• an upper wall extending from a first end to a second end, the upper wall including a central portion and an end wall extending perpendicular to the central portion at the second end, the end wall configured to abut the border flange of the filter;
• a lower wall spaced apart from the upper wall and extending from a first end to a second end, the lower wall including a central portion extending parallel to the central portion of the upper wall and an end wall extending perpendicular to the central portion at the second end, the end wall configured to abut the border flange of the filter;
• a first rail extending between the upper wall and the lower wall;
• and
• a second rail, spaced apart from the first rail, extending between the upper wall and the lower wall;
• wherein the upper wall, the lower wall, the first rail, and the second rail form a four-sided perimeter at the first end of the filter frame adapter configured to extend around the filter and wherein the upper wall and the lower wall form a two-sided perimeter proximate the second end of the filter frame adapter.

A method of replacing filter media of a filter unit, the method comprising:

• removing the filter unit from an opening in a partition;
• removing a fastener from aligned apertures in a first filter having filter media and a flange extending around the filter media and a filter frame adapter extending from a first end to a second end having an upper mounting surface and a lower mounting surface at the second end each configured to mount to a flange of the first filter, the filter frame adapter also including a four-sided perimeter configured to extend around the filter media at the second end;
• aligning apertures in a second filter having filter media and a flange extending around the filter media with the apertures of the filter frame adapter;
• locating the fastener in the aligned apertures of the filter frame adapter and the second filter to couple the second filter to the filter frame adapter;
• and
• coupling the filter frame adapter in the opening to the partition.

A filter frame adapter configured to couple a V-cell filter to a partition, the filter frame adapter comprising:

• a first wall including a central portion extending from a first end to a second end, a first end wall located at the first end, and a second end wall located at the second end;
• a second wall including a central portion extending from a first end to a second end, a first end wall located at the first end, and a second end wall located at the second end;
• a first rail extending between the first wall and the second wall;
• a second rail spaced apart from the first rail and extending between the first wall and the second wall;
• and
• a fastener configured to releasably couple the filter frame adapter to the V-cell filter;
• wherein at least one of the walls includes a first coupling feature configured to allow the filter frame adapter to be releasably coupled to the partition.
