Grid cover for filter system

1. A filter system comprising:

at least one support strut defining an opening;

a filter received in the opening defined by the at least one support strut and being supported by the at least one support strut; and

a grid cover comprising a front wall and a pair of opposing arms extending rearward from the front wall at an inward angle, wherein the opposing arms project inward towards each other from the front wall, wherein the pair of opposing arms of the grid cover overlie at least a portion of said at least one support strut and are disposed between said at least one support strut and the filter, wherein the grid cover is removable from said at least one support strut,

wherein the front of the filter engages one of the pair of opposing arms of the grid cover such that the grid cover functions as a shim between the filter and the support strut.

2. The filter system set forth in claim 1 , wherein said at least one support strut comprises a plurality of support struts secured to one another, wherein the opening defined by the plurality of support struts comprises a plurality of openings, wherein the filter comprises a plurality of filters received in the plurality of openings, wherein the grid cover comprises a plurality of grid covers.

3. A method of assembling a filter system comprising:

placing a filter in an opening defined by a support grid, wherein the support grid includes a plurality of struts; and

placing a grid cover on the support grid, such that an arm of the grid cover extends at an inward angle and is sandwiched between the filter and at least one of the plurality of struts, and a front wall of the grid cover is adjacent a front side of the filter, wherein a front of the filter engages the arm of the grid cover such that the grid cover functions as a shim between the filter and the support strut.

4. The method of assembling a filter system set forth in claim 3 , wherein said placing a grid cover on the support grid comprises removably securing the grid cover to said at least one of the plurality of struts.

5. A grid cover for a grid of a filter system, the grid including a plurality of struts defining adjacent openings in which adjacent filters are received, the grid cover comprising:

a front wall; and

a pair of opposing arms extending rearward from the front wall at an inward angle, wherein the opposing arms project inward towards each other from the front wall, and

wherein the pair of opposing arms are configured to clip onto one of the plurality of struts of the grid and be disposed between the one of the plurality of struts and the adjacent filters received in the adjacent openings of the grid,

wherein the opposing arms project rearward and inward towards each other from the front wall to define an interior sized and shaped to receive the one of the plurality of struts of the grid,

wherein the pair of opposing arms are configured to engage the fronts of the adjacent filters such that the grid cover functions as a shim between the filters and the support strut.

6. The grid cover of claim 5 , wherein the interior includes a throat portion and a mouth portion, wherein the opposing arms flare away from one another adjacent the throat portion to define the mouth portion.

7. The grid cover of claim 5 , wherein the two opposing arms comprises detents disposed in the interior to engage the strut.

8. The grid cover of claim 5 , further comprising rear flanges projecting outward from the opposing arms, wherein the rear flanges are configured to engage at least a portion of the one of the plurality of struts.

9. The grid cover of claim 5 , wherein the opposing arms each comprise a detent having an inward portion projecting inward and towards the front wall and an outward portion extending outward and away from the front wall.

10. The grid cover of claim 9 , wherein the opposing arms each comprise a flange portion ending from the outward portion of detent, wherein the flange portion and the front wall are planar.

11. The filter system of claim 1 , wherein the front of the filter defines an opening and includes a generally rigid frame configured to hold open the front of the filter.

12. The method of claim 3 , wherein a front of the filter defines an opening and includes a generally rigid frame configured to hold open the front of the filter.
