Abstract

An adapter is provided for placement within a furnace filter bay having a flow of air therethrough. The filter bay is for receiving a furnace filter. The adapter includes a filter abutment face for abutment with at least a portion of the furnace filter, a mounting face parallel to the flow of air and attachment means permitting removable attachment of the adapter to the furnace filter bay. The adapter allows filters of smaller depth than the filters originally designed for use within the filter bay to be used, thereby eliminating the need for purchasing the original filters. A brace is also provided for the same purpose. A kit is described that includes the adapter and/or brace, along with instructions for installation thereof within the filter bay.

Claims

1. ) An adapter for placement within a furnace filter bay having a flow of air therethrough, the filter bay for receiving a furnace filter, the adapter comprising:

a) a filter abutment face for abutment with at least a portion of the furnace filter;

b) a mounting face parallel to the flow of air; and

,

c) an attachment means permitting removable attachment of the adapter to the furnace filter bay.

2. ) The adapter according to claim 1, wherein the attachment means consists of a magnet or an adhesive.

3. ) The adapter according to claim 2, wherein the attachment means is on the mounting face.

4. ) The adapter according to claim 2, wherein the mounting face is on a mounting portion of the adapter.

5. ) The adapter according to claim 4, wherein the adapter further comprises a magnet channel on the mounting portion and wherein the attachment means is the magnet and is inserted within the magnet channel.

6. ) The adapter according to claim 5, wherein the mounting portion has a magnet channel face parallel to and oppositely oriented from the mounting face and wherein the magnet channel is located on the magnet channel face.

7. ) The adapter according to claim 5, wherein the magnet is positionable within the magnet channel.

8. ) The adapter according to claim 1, wherein the filter abutment face is perpendicular to the mounting face.

9. ) The adapter according to claim 8, wherein the filter abutment face is on a filter channel for receiving an edge of the furnace filter.

10. ) The adapter according to claim 1, wherein the filter abutment face is non-planar.

11. ) A furnace filter brace for placement within a furnace filter bay having a flow of air therethrough, the filter bay for receiving a furnace filter, the brace comprising:

a) a filter abutment face for abutment with at least a portion of the furnace filter;

b) a filter bay abutment face for abutment against an interior retainer portion of the filter bay; and

,

c) a first variable-length member diagonally or horizontally between the filter abutment face and filter bay abutment face.

12. ) The brace of claim 11, wherein the filter abutment face is on a rectangular frame.

13. ) The brace of claim 11, further comprising a second variable-length member between the first filter abutment face and the filter bay abutment face.

14. ) The brace of claim 13, wherein the filter bay abutment face is a first filter bay abutment face and wherein the brace further comprises:

a) a second filter bay abutment face; and

b) a third variable-length member and a fourth variable length member, wherein the third and fourth variable-length members extend between the filter abutment face and the second filter bay abutment face.

15. ) The brace of claim 11, wherein the filter abutment face is a first filter abutment face, the filter bay abutment face is a first filter bay abutment face, the interior retainer portion is a first interior retainer portion, and wherein the brace further comprises:

a) a second filter abutment face for abutment with at least a portion of the furnace filter, the second filter abutment face parallel with the first filter abutment face;

b) a second filter bay abutment face for abutment with a second interior retainer portion of the filter bay; and

c) a second variable-length member between the second filter abutment face and the second filter bay abutment face pivotally connected to the first variable-length member.

16. ) A kit for adapting a furnace filter bay to receive a furnace filter, the filter bay having a flow of air therethrough, the kit comprising:

a) an adapter for placement within the furnace filter bay including a filter abutment face for abutment with at least a portion of the furnace filter and a mounting face parallel to the flow of air;

b) attachment means permitting removable attachment of the adapter to the furnace filter bay; and

,

c) a set of instructions for attachment and placement of the adapter within the filter bay.

17. ) The kit according to claim 16, wherein the kit further comprises the furnace filter.

18. ) The kit according to claim 16, wherein the kit comprises at least two adapters.

19. ) The kit according to claim 16, wherein the set of instructions includes instructions to:

a) trim the adapter to a length commensurate with a length of the filter or an interior width of the filter bay;

b) place the adapter proximate a downstream end of the filter bay such that the filter abutment face abuts the furnace filter when inserted at the downstream end of the filter bay; and

,

c) insert the furnace filter at the downstream end of the filter bay.

20. ) The kit according to claim 16, wherein the set of instructions includes instructions to:

a) attach the attachment means to the adapter; and

,

b) attach the adapter to an interior of the filter bay.

21. ) The kit according to claim 16, wherein:

a) the mounting face is on a mounting portion of the adapter, the mounting portion having a magnet channel face parallel to and oppositely oriented from the mounting face, the adapter further including a magnet channel on the magnet channel face;

b) the attachment means includes a magnet; and

,

c) the set of instructions include an instruction to insert the magnet in the magnet channel.

22. ) A kit for adapting a furnace filter bay to receive a furnace filter, the filter bay having a flow of air therethrough, the kit comprising:

a) a brace for placement within the furnace filter bay including a filter abutment face for abutment with at least a portion of the furnace filter and a filter bay abutment face for abutment with a portion of the filter bay; and

b) a set of instructions for placement of the brace within the filter bay.

23. ) The kit according to claim 22, wherein the kit further comprises the furnace filter.

24. ) The kit according to claim 22, wherein the kit comprises at least two braces.

25. ) The kit according to claim 22, wherein the set of instructions includes instructions to:

a) insert the furnace filter at the downstream end of the furnace filter bay; and

b) insert the brace into position in the furnace filter bay.

26. ) The kit according to claim 25, wherein the instructions specify to carry out step a) prior to carrying out step b).
