Claims20
An air filter cartridge comprising:
- (a) a filter media pack having first and second, opposite, flow faces;
- the filter media pack comprising fluted media secured to facing media to define inlet and outlet flow channels extending between the first and second, opposite, flow faces;
- (i) the filter media pack being closed to passage of air therethrough, from the first flow face to the opposite second flow face, without filtering passage through the media;
- (ii) the first flow face being generally planar and perpendicular to a direction of extension of the media between the inlet and outlet flow faces;
- and,
- (iii) the media pack having a non-circular cross-sectional definition in a direction parallel to the first flow face;
- and,
- (b) a housing seal arrangement comprising a perimeter seal extending completely around the media pack;
- (i) the housing seal arrangement including a seal surface positioned for sealing engagement with a housing component in use;
- (ii) the seal surface extending completely around the media pack and including at least one pinch seal surface portion, configured to sealingly engage a housing as it extends in a direction around the media pack, that also extends in a direction non-parallel to the first flow face;
- (A) the pinch seal surface portion being spaced from at least from the second flow face in a direction toward the first flow face, as the housing seal arrangement extends around the media pack;
- and,
- (B) the housing seal arrangement having a portion molded to the filter media pack;
- and,
- (iii) the housing seal arrangement comprises a base and the pinch seal lip;
- (A) the pinch seal lip being positioned on, and molded integral with, the base;
- and,
- (B) the base and pinch seal lip defining a trough between at least a portion of the pinch seal lip and the media pack.

- in an opposite direction from the first flow face;
- and, in the same direction as the second flow face;
- (ii) the pinch seal surface portion including at least one seal surface portion, as it extends in a direction around the media pack, that also extends in a direction non-parallel to the first flow face;
- and,
- (iii) the pinch seal surface portion including at least one seal surface portion, as it extends in a direction around the media pack, that also extends in a direction parallel to the first flow face;
- (iv) the pinch seal surface portion being spaced at least from the second flow face in a direction toward the first flow face, as the housing seal arrangement extends around the media pack;
- and,
- (v) the housing seal arrangement having a portion molded to the filter media pack.
