1. 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; and,(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;(b) a housing seal arrangement comprising a perimeter seal extending completely around the media pack (i) the housing seal arrangement comprising a pinch seal lip having a seal surface positioned for sealing engagement with a housing component in use; the seal surface facing, generally, in an opposite direction from the first flow face and, generally, in the same direction as the second flow face;(ii) the seal surface extending completely around the media pack and including at least one seal surface portion, as it extends in a direction around the media pack, that is non-parallel to the first flow face. 2. An air filter cartridge according to claim 1 wherein: (a) at least a portion of the first seal surface of the pinch seal lip, that extends in a direction non-parallel to the first flow face, extends at an angle of at least 2° relative to the first flow face. 3. An air filter cartridge according to claim 1 wherein: (a) at least a portion of the first seal surface of the pinch seal lip that extends in a direction non-parallel to the first flow face extends at an angle of no greater than 45° relative to the first flow face. 4. An air filter cartridge according to claim 1 wherein: (a) at least a portion of the first seal surface of the pinch seal lip, that extends in a direction non-parallel to the first flow face, extends at an angle within the range of 5°-15° relative to the first flow face. 5. An air filter cartridge according to claim 1 wherein: (a) the pinch seal lip includes opposite surfaces each of which has at least one surface portion that, in extending in a direction around the media, extends non-parallel to the first flow face. 6. An air filter cartridge according to claim 5 wherein: (a) the pinch seal lip has a portion extending at an angle of at least 2° relative to the first flow face. 7. An air filter cartridge according to claim 5 wherein: (a) the pinch seal lip has a portion extending at an angle within the range of 5°-15° relative to the first flow face. 8. An air filter cartridge according to claim 1 wherein: (a) the media pack has a non-circular cross-sectional definition in a direction parallel to the first flow face. 9. An air filter cartridge according to claim 8 wherein: (a) the media pack defines a first pair of first and second opposite sides; and, a second pair of opposite sides extending between the first pair of first and second opposite sides. 10. An air filter cartridge according to claim 9 wherein: (a) the pinch seal lip extends along a path non-parallel to the first flow face, in extension across at least one of the first pair of opposite sides. 11. An air filter cartridge according to claim 10 wherein: (a) each one of the first pair of opposite sides, of the media pack, has a panel secured thereto; (i) the pinch seal lip extending across the panels. 12. An air filter cartridge according to claim 10 wherein: (a) the housing seal arrangement comprises a base and the pinch seal lip; (i) the pinch seal lip being positioned on, and molded integral with, the base; and,(ii) the base and pinch seal lip define a trough between at least a portion of the pinch seal lip and the media pack. 13. An air filter cartridge according to claim 1 wherein: (a) the media comprises a stack of strips of fluted media secured to facing media. 14. An air filter cartridge according to claim 13 wherein: (a) the pinch seal lip extends along a path non-parallel to the first flow face, in extension across at least one of the first pair of opposite sides. 15. An air filter cartridge according to claim 14 wherein: (a) the housing seal arrangement comprises a base and the pinch seal lip; (i) the pinch seal lip being positioned on, and molded integral with, the base; and,(ii) the base and pinch seal lip define a trough between at least a portion of the pinch seal lip and the media pack. 16. An air filter cartridge according to claim 1 wherein: (a) the housing seal arrangement comprises a base and the pinch seal lip; (i) the pinch seal lip being positioned on, and molded integral with, the base; and,(ii) the base and pinch seal lip define a trough between at least a portion of the pinch seal lip and the media pack. 17. An air filter cartridge comprising: (a) a filter media pack having first and second opposite flow faces; the filter media pack comprising fluted filter 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; and,(ii) the filter media pack having a configuration with the first flow face being planar in extension across a direction of flow through the media pack;(b) a housing seal arrangement comprising a perimeter seal extending around the media pack; (i) the housing seal arrangement being positioned spaced from at least one of the first and second, opposite, flow faces;(ii) the perimeter seal having a first section that extends across a portion of the media pack; along a path not continuously parallel to the first flow face; and,(iii) the housing seal arrangement including a base and a 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. 18. An air filter cartridge according to claim 1 wherein: (a) the filter media pack comprises a stacked construction of strips of filter media comprising fluted media secured to facing media. 19. An air filter cartridge according to claim 17 including: (a) first and second side panels positioned, respectively, on a first pair of opposite sides of the media pack. 20. An air filter cartridge according to claim 19 wherein: (a) the housing seal arrangement extends across the first and second side panels.
