1. An air filter cartridge comprising: (a) a z-filter media construction having: an inlet flow face; an opposite outlet flow face; and, a non-circular outer perimeter; (i) the z-filter media construction comprising an alternating construction of fluted media secured to non-fluted media;(b) a frame m
1. An air filter cartridge comprising: (a) a z-filter media construction having: an inlet flow face; an opposite outlet flow face; and, a non-circular outer perimeter; (i) the z-filter media construction comprising an alternating construction of fluted media secured to non-fluted media;(b) a frame member mounted on, and secured to, the z-filter media construction, the frame member comprising: (i) a radially inwardly extending lip that hooks over the media construction and abuts one of the flow faces;(ii) a band that extends completely, peripherally, around the media construction; and,(iii) a radially, outwardly, extending projection that is positioned on the band and extends completely peripherally around the media construction; and,(c) a seal member extending completely, peripherally, around the band and the media construction and supported by the radially, outwardly, extending projection. 2. An air filter cartridge according to claim 1, wherein the seal member is constructed to form an axially directed seal against the frame member radially, outwardly, extending projection. 3. An air filter cartridge according to claim 1, wherein the frame member comprises a cross-brace construction. 4. An air filter cartridge according to claim 1, wherein the z-filter media has an obround shape. 5. An air filter cartridge according to claim 1, wherein the z-filter media has a race track shape. 6. An air filter cartridge according to claim 1, wherein the radially, outwardly, extending projection is located between the inlet flow face and the outlet flow face. 7. An air filter cartridge according to claim 1, wherein the seal member, when the air filter cartridge is located within a housing, is constructed to form a seal between the radially, outwardly extending projection and the housing. 8. An air filter cartridge according to claim 1, wherein the seal member is constructed to form an axially directed seal against the frame member radially, outwardly, extending projection. 9. An air filter cartridge according to claim 3, wherein the cross-brace construction extends across the inlet flow face. 10. An air filter cartridge according to claim 1, wherein the z-filter media construction comprises a coiled construction of the fluted media and the non-fluted media. 11. An air filter cartridge according to claim 1, wherein the frame member is secured to the z-filter media construction by adhesive. 12. An air filter cartridge comprising: (a) a z-filter media construction having: an inlet flow face; an opposite outlet flow face; and, a non-circular outer perimeter with two opposite rounded end sections; (i) the z-filter media construction comprising a coiled construction of fluted media secured to non-fluted media; and,(ii) the media construction including a non-cylindrical central core comprising a member including a non-cylindrical recess adjacent the outlet flow face and defined between two ends of the core located adjacent the outlet flow face;(b) a frame member mounted on, and secured to, the z-filter media construction, the frame member comprising: (i) a band that extends completely, peripherally, around the media construction; and,(ii) radially, outwardly, extending projection that is positioned on the band and extends completely peripherally around the media construction; and,(c) a seal member extending completely, peripherally, around the band and the media construction and supported by the radially, outwardly, extending projection. 13. An air filter cartridge according to claim 12, wherein the seal member is constructed to form an axially directed seal against the frame member radially, outwardly, extending projection. 14. An air filter cartridge according to claim 12, wherein the z-filter media has an obround shape. 15. An air filter cartridge according to claim 12, wherein the z-filter media has a race track shape. 16. An air filter cartridge according to claim 12, wherein the seal member, when the air filter cartridge is located within a housing, is constructed to form a seal between the radially, outwardly, extending projection and the housing. 17. An air filter cartridge according to claim 12, wherein the frame member comprises a cross-brace construction. 18. An air filter cartridge according to claim 17, wherein the cross-brace construction extends across the inlet flow face. 19. An air filter cartridge according to claim 12, wherein the frame member is secured to the z-filter media construction by adhesive. 20. An air filter cartridge according to claim 12, wherein the air filter cartridge prevents leakage by passage along the core. 21. An air filter cartridge according to claim 12, wherein the core assists in manufacturing of the coiled construction. 22. An air filter cartridge according to claim 12, wherein the z-filter media construction is adhered to the core.
