Abstract

This document presents an apparatus for a flexible air filter media that can be configured for shipping and storage having one or more flexible inserts mounted to the filter media along one or more portions of the accordion folds of the air filter material. The current invention permits the air filter apparatus to fold along both X and Y axes, create a tri-fold, and bend in a manner that provides for a much smaller volume for shipping purposes. The invention also permits attaching the flexible material to the center of the filter media and also inserts which allow sections of the air filter media to be nested one into another to reduce both shipping and storage volume.

Claims (20)

1. An air filter apparatus, comprising:

an air filter material panel having a plurality of exterior edges;

a plurality of flexible seals each connected to a respective one of the exterior edges of the air filter material panel thereby forming a respective exterior edge of the air filter apparatus;

a plurality of flexible inserts mounted to the filter material panel by the flexible seals, each flexible insert inserted into a respective one of the plurality of flexible seals; and

bonding material connecting the plurality of flexible seals each to the respective one of the exterior edges of the air filter material panel;

wherein, by flexing the flexible inserts, the air filter material panel is foldable along multiple non-parallel axes from an expanded configuration of the air filter apparatus ready for use in an HVAC system to a reduced configuration of the air filter apparatus that is volumetrically reduced relative to the expanded configuration.

2. The filter apparatus of claim 1 , wherein the air filter material panel does not suffer damage when the air filter apparatus is transitioned between the expanded configuration and the reduced configuration.

3. The filter apparatus of claim 1 , wherein the flexible inserts comprise at least one of cloth, woven matting, flexible plastic, neoprene, mylar, rubberized flexible material, and metal.

4. The filter apparatus of claim 1 , wherein the bonding material comprises at least one of adhesive material, stitching, clamping, stapling, and fusing.

5. The air filter apparatus of claim 1 , where the air filter media panel may be folded along the X axis and Y axis simultaneously to reduce the physical dimensions of the air filter.

6. The air filter apparatus of claim 1 , where the air filter media panel may be folded along multiple flexible inserts to reduce the physical dimensions of the air filter apparatus.

7. The air filter apparatus of claim 1 , wherein, in the reduced configuration, the air filter apparatus is no more than 15 inches long, no more than 12 inches high, and no more than 2 inches thick.

8. The air filter apparatus of claim 1 , wherein, when the air filter apparatus is used in an HVAC system, the plurality of flexible seals maintain a seal with a housing of the HVAC system housing to prevent unfiltered air from getting by the air filter apparatus.

9. An air filter assembly, comprising:

an air filter material panel having a plurality of exterior edges;

a plurality of flexible exterior seals each connected to a respective one of the exterior edges of the air filter material panel thereby forming a respective exterior edge of the air filter assembly;

a plurality of flexible inserts mounted to the filter material panel by the flexible seals, each flexible insert inserted into a respective one of the plurality of flexible seals; and

wherein, by flexing the flexible inserts, the air filter material panel is foldable along an X axis and a Y axis to reduce physical dimensions of the air filter assembly.

10. The air filter assembly of claim 9 , wherein each flexible seal has a hollow interior in which the respective flexible insert is inserted.

11. The air filter apparatus of claim 1 , wherein each flexible seal has a hollow interior in which the respective flexible insert is inserted.
