1. An air filter cartridge comprising: (a) a media pack including opposite inlet and outlet ends: (i) the media pack comprising filter media defining a set of inlet flutes and a set of outlet flutes extending between the inlet and outlet ends; and(ii) the media pack being closed to flow of unfiltered air therethrough without passage through filter media of the media pack;(b) a preform positioned adjacent a first one of the inlet and outlet ends of the media pack; (i) the preform including a radial seal support and,(ii) the radial seal support having an outside surface;(c) a seal member positioned on the preform; the seal member including: (i) a radial seal region positioned adjacent the radial support outside surface; and(ii) a single, beveled, outer axial surface including a straight section at least 4 mm long extending at an angle, HE, of 30° to 60°, inclusive, relative to a plane perpendicular to a direction between the media pack opposite inlet and outlet ends;(iii) the beveled outer surface being positioned in extension between a portion of the radial seal region and the outer tip of the seal member. 2. An air filter cartridge according to claim 1 wherein: (a) The single, beveled, outer axial surface of the seal member has a length within the range of 6 to 16 mm, inclusive, and extends at an angle, HE, within the range of 35° to 55°. 3. An air filter cartridge according to claim 1 wherein: (a) the seal member is a molded-in-place seal member; and,(b) the preform is secured to the media pack with an adhesive separate from the seal member. 4. An air filter cartridge according to claim 1 wherein: (a) the seal member is integral with a molded-in-place overmold securing the preform to the media pack. 5. An air filter cartridge according to claim 1 wherein: (a) the media pack comprises a coiled arrangement of a fluted sheet secured to a facing sheet. 6. An air filter cartridge according to claim 1 wherein: (a) the media pack has a circular outer periphery. 7. An air filter cartridge according to claim 1 wherein: (a) the media pack has an oval outer periphery. 8. An air filter cartridge according to claim 7 wherein: (a) the media pack has a racetrack outer periphery, with opposite curved ends and opposite straight sides. 9. An air filter cartridge according to claim 1 wherein: (a) the radial seal support has an inside surface opposite the outside surface;(b) the seal member is part of a molded-in-place arrangement including an inside region adjacent the preform inside surface; (i) the inside region having a tip; and(c) the preform including a radially, inwardly, directed lip extending across the tip of the inside region. 10. An air filter cartridge according to claim 1 including: (a) a second preform mounted on an end of the media pack opposite the seal member. 11. An air filter cartridge according to claim 1 wherein: (a) the second pre-form includes a plurality of scallop-shaped fingertip receiving regions thereon. 12. An air filter cartridge comprising: (a) a media pack including opposite inlet and outlet ends; (i) the media pack comprising filter media defining a set of inlet flutes and a set of outlet flutes extending between the inlet and outlet ends; and,(ii) the media pack being closed to flow of unfiltered air therethrough without passage through filter media of the media pack;(b) a preform positioned adjacent a first one of the inlet and outlet ends of the media pack; (i) the perform including a radial seal support; and,(ii) the radial seal support having an outside surface(c) a seal member positioned on the preform; (i) the seal member including: a radial seal region positioned adjacent the radial support outside surface; and(d) a second preform mounted on an end of the media pack opposite the seal member; (i) the second preform including a plurality of scallop-shaped fingertip receiving regions thereon.
