Method and apparatus for providing test ports

1. A filter, comprising:

a pleated v-shaped filter media having a filter media front face and a filter media rear face, the pleats extending to a predefined height;

a test port member having a first through port extending between a test port front face and an opposing test port rear face of the test port member, and wherein the test port member further includes a three-sided outer periphery, wherein the three-sided outer periphery includes an inwardly facing side and two remaining sides extending between the test port front face and the opposing test port rear face;

a peripheral frame receiving the filter media and the test port member wherein the peripheral frame maintains the filter media and the test port member in an adjacent relationship;

wherein the test port member and the v-shaped filter media are retained by the peripheral frame and wherein the test port member is positioned between the peripheral frame and a truncated portion of the pleated v-shaped filter media, wherein the inwardly facing side of the test port member engages an outer periphery of the filter media and the two remaining sides of the three-sided outer periphery of the test port member engages the frame, and wherein the test port member defines one or more cavities with the peripheral frame intersected by the first through port;

the truncated portion of the pleated v-shaped filter media having a shape of a triangular truncated portion and wherein the test port member matches the triangular truncated portion of the pleated v-shaped filter media;

the test port member first through port is formed on a recessed end wall, the recessed end wall forming a first cavity and a second cavity, the first cavity and the second cavity separated by the recessed end wall, the first through port receiving a plug;

the recessed end wall positioned between an upstream side and downstream side of the filter;

wherein the test port front face includes a first flange and the test port rear face includes a second flange extending inwardly towards the truncated portion of the pleated v-shaped filter media, wherein the recessed end wall extends in an opposite direction to the first flange and the second flange away from the truncated portion of the of the pleated v-shaped filter media, wherein the recessed end wall, the first flange, and the second flange are substantially parallel to each other, wherein the first flange extends over a portion of the filter media front face and the second flange extends over a portion of the filter media rear face to retain the pleated v-shaped filter media between the first flange and the second flange;

wherein the recessed end wall retains the plug within the first cavity and wherein the second cavity extends to the upstream side of the filter;

wherein the filter is rectangular; and

wherein the test port member further comprises one or more fill members within the second cavity extending from the recessed end wall to the upstream side of the filter, wherein the one or more fill members have a second through port in fluid communication with the first through port, and wherein the second through port of the fill member extends from the first through port to the upstream side of the filter.

2. The filter of claim 1 wherein the plug is an aerosol plunger at rest in a closed position.

3. The filter of claim 1 wherein the second through port of the one or more fill members receives the plug.

4. The filter of claim 1 wherein the one or more fill members only occupies the second cavity.

5. The filter of claim 1 wherein the one or more fill members extend from an upstream surface of the recessed end wall to an upstream flange of the peripheral frame.

6. The filter of claim 1 wherein the one or more fill members is an adhesive.

7. The filter of claim 1 wherein the one or more fill members is triangular in shape.

8. A filter, comprising:

a rectangular frame having a rectangular inner periphery and surrounding a single filter media and a test port member, and wherein the rectangular frame includes a downstream flange and an upstream flange;

the filter media being a pleated v-shaped filter media having a filter media front face and a filter media rear face, the pleats extending to a predefined height;

the single filter media further having a triangular truncated portion removed at a truncated corner of the single filter media;

the test port member being a triangular shaped test port member having a first through port extending between a test port front face and an opposing test port rear face;

wherein the test port member further includes an inwardly facing side extending between the test port front face and the opposing test port rear face;

the rectangular frame receiving and retaining the single filter media and the test port member wherein the rectangular frame maintains the single filter media and the test port member in an adjacent relationship to form a rectangular outer periphery engaging the inner periphery of the rectangular frame;

wherein the test port member is positioned between the rectangular frame and the triangular truncated portion of the pleated v-shaped filter media at a corner of the rectangular frame, the inwardly facing side of the test port member engaging an outer periphery of the single filter media;

wherein the test port member matches the triangular truncated portion of the pleated v-shaped filter media;

the test port member first through port formed on a recessed end wall of the test port member, the recessed end wall forming a first cavity and a second cavity of the test port member, the first cavity and the second cavity separated by the recessed end wall wherein the second cavity extends to the filter media rear face, and wherein the recessed end wall extends away from the pleated v-shaped filter media;

the test port member having a first flange and a second flange extending in an opposite direction to the recessed end wall inwardly towards the pleated v-shaped filter media, wherein the recessed end wall, the first flange, and the second flange are substantially parallel to each other, wherein the first flange extends over a portion of the filter media front face and the second flange extends over a portion of the filter media rear face;

an adhesive on the test port member inwardly facing side to adhere the test port inwardly facing side to the truncated corner of the single filter media;

the test portion member includes a fill member within the second cavity extending from the recessed end wall to the upstream flange of the rectangular frame, wherein the fill member includes a second through port in fluid communication with the first through port, and wherein the second through port of the fill member extends from the recessed end wall to the upstream flange of the rectangular frame; and

wherein the first through port of the recessed end wall and the second through port of the fill member receives a plug whereby retaining the plug within the first cavity and the second cavity.

9. The filter of claim 8 wherein the plug is an aerosol plunger at rest in a closed position.

10. The filter of claim 8 wherein the fill member is an adhesive.

11. The filter of claim 8 wherein the fill member is a triangular plastic member.
