the blank of filter media further comprises at least one of a first pleated extended portion to extend the pleated filter media along a first truncated cone shaped surface defined by the pleated filter media from a relatively minimum cross sectional area to the cross sectional area at the first end; and a second pleated extended portion to extend the pleated filter media along a second truncated cone shaped surface defined by the pleated filter media from the relatively minimum cross sectional area to the cross sectional area at the second end.

2. The filter element according to claim 1 , further comprising:

a top cap disposed at the first end; and

a bottom cap disposed at the second end.

3. The filter element according to claim 1 , further comprising:

a spiral roving disposed about the filter element.

4. The filter element according to claim 1 , further comprising:

a pair of truncated cone-shaped filters generated by cutting the filter element in half.

5. The filter element according to claim 1 , further comprising:

a filter housing to contain the filter element.

6. The filter element according to claim 5 , further comprising:

an inlet disposed in the filter housing, the inlet being at a midpoint along a long axis of the filter.

7. The filter element according to claim 6 , further comprising:

an outlet disposed in the filter housing, the outlet being disposed in cooperative alignment with the long axis of the filter.

8. A filter cartridge, comprising:

a filter element including:

a center tube having a first end and a second end; and

a blank of a filter media folded into a plurality of triangles, wherein each triangle is disposed adjacent to another of the plurality of triangles to form a series of triangular pleats to form a pleated filter media, the pleated filter media being disposed about the center tube, wherein a cross sectional area of the pleated filter media proximal to each of the first end and the second end is greater than a cross sectional area of the pleated filter media at a point between the first end and the second end;

the blank of filter media further comprising a first pleated extended portion to extend the pleated filter media along a first truncated cone shaped surface defined by the pleated filter media from a relatively minimum cross sectional area to the cross sectional area at the first end; and a second pleated extended portion to extend the pleated filter media along a second truncated cone shaped surface defined by the pleated filter media from the relatively minimum cross sectional area to the cross sectional area at the second end;

a top cap disposed at the first end; and

a bottom cap disposed at the second end.

9. The filter cartridge according to claim 8 , further comprising:

a spiral roving disposed about the filter element.

10. The filter cartridge according to claim 8 , further comprising:

a pair of truncated cone-shaped filters generated by cutting the filter element in half.

11. The filter cartridge according to claim 8 , further comprising:

a filter housing to contain the filter element.

12. The filter cartridge according to claim 11 , further comprising:

an inlet disposed in the filter housing, the inlet being at a midpoint along a long axis of the filter.

13. The filter cartridge according to claim 12 , further comprising:

an outlet disposed in the filter housing, the outlet being disposed in cooperative alignment with the long axis of the filter.

14. A filter housing, comprising:

an inlet;

an outlet;

an internal volume to house a filter element, the filter element including:

a center tube having a first end and a second end; and

a blank of a filter media folded into a plurality of triangles, wherein each triangle is disposed adjacent to another of the plurality of triangles to form a series of triangular pleats to form a pleated filter media, the pleated filter media being disposed about the center tube, wherein a cross sectional area of the pleated filter media proximal to each of the first end and the second end is greater than a cross sectional area of the pleated filter media at a point between the first end and the second end;

the blank of filter media further comprising a first pleated extended portion to extend the pleated filter media along a first truncated cone shaped surface defined by the pleated filter media from a relatively minimum cross sectional area to the cross sectional area at the first end; and a second pleated extended portion to extend the pleated filter media along a second truncated cone shaped surface defined by the pleated filter media from the relatively minimum cross sectional area to the cross sectional area at the second end;

a top cap disposed at the first end;

a bottom cap disposed at the second end; and

a toroidal chamber disposed about a center portion of the filter element configured to evenly disperse a flow of incoming fluid about the filter element.

15. The filter housing according to claim 14 , further comprising:

a spiral roving disposed about the filter element.

16. The filter housing according to claim 14 , wherein the inlet is disposed at a midpoint along a long axis of the filter.

17. The filter cartridge according to claim 16 , wherein the outlet is disposed in cooperative alignment with the long axis of the filter.
