First claim

What is claimed is:

1. An air filter cartridge comprising:
(a) first and second, opposite, end caps;
(b) pleated filter media: extending between the first and second end caps and surrounding a central axis to define an open interior;
(i) the pleated media having a tapered outer perimeter in extension between the first and second end caps; and,
(ii) the pleated media having a larger perimeter adjacent the first end cap than adjacent the second end cap;

(c) the first end cap having an air flow aperture therethrough;
(i) the first end cap including a housing seal member thereon; and,

(d) the second end cap being closed and having a receiver recess portion projecting toward the first end cap and defining an open receiver facing a direction away from the first end cap;
(i) the receiver recess portion having a non-circular shape in cross-section in a plane perpendicular to the open interior and the central axis.

2. An air filter cartridge according to claim 1 wherein:
(a) the receiver recess comprises a plurality of radially outwardly directed portions.

3. An air filter cartridge according to claim 2 wherein:
(a) the receiver recess comprises a plus-shaped recess.

4. An air filter cartridge according to claim 2 including:
(a) a liner extending between the first and second end caps.

5. An air filter cartridge according to claim 1 wherein:
(a) the media has a conical angle of at least 1°.

6. An air filter cartridge according to claim 1 wherein:
(a) the housing seal member on the first end cap is a radially directed housing seal member.

7. An air filter cartridge according to claim 6 wherein:
(a) the radially directed housing seal member is radially outwardly directed.
