1. An air filter cartridge comprising: (a) a z-filter media construction comprising a fluted media secured to a non-fluted media, the z-filter media construction having an first flow face and second flow face, wherein the first flow face and the second flow face are separated from each other in an axial direction;(b) a frame member mounted on, and secured to, the z-filter media construction and comprising a first radially projecting member and a second radially projecting member, wherein the first radially projecting member and the second radially projecting member are axially spaced apart; and(c) a seal member including a portion thereof located around the frame member and between the first radially projecting member and the second radially projecting member. 2. An air filter cartridge according to claim 1, wherein the z-filter media has an obround cross-section shape. 3. An air filter cartridge according to claim 1, wherein the z-filter media has a racetrack cross-section shape. 4. An air filter cartridge according to claim 1, wherein the z-filter media construction comprises a wound construction resulting from winding the fluted media secured to the non-fluted media. 5. An air filter cartridge according to claim 1, wherein the fluted media is secured to the non-fluted media at different locations thereby forming inlet flutes and outlet flutes. 6. An air filter cartridge according to claim 1, wherein the first flow face and the second flow face are parallel. 7. An air filter cartridge according to claim 1, wherein the frame member comprises a cross-brace construction located adjacent the first flow face or the second flow face. 8. An air filter cartridge according to claim 1, wherein the frame member is adhered to an outer periphery of the z-filter media construction. 9. An air filter cartridge according to claim 1, wherein the seal member is constructed to form an axially directed seal against an air cleaner housing when installed in the air cleaner housing. 10. An air filter cartridge according to claim 1, wherein the seal member extends completely, peripherally, around the frame member. 11. An air filter cartridge according to claim 1, wherein the seal member extends completely, peripherally, around the z-filter media construction. 12. An air filter cartridge according to claim 1, wherein one of the first radially projecting member or the second radially projecting member extends radially, outwardly. 13. An air filter cartridge according to claim 1, wherein one of the first radially projecting member or the second radially projecting member extends radially inwardly. 14. An air filter cartridge according to claim 13, wherein the at least one of the first radially projecting member or the second radially projecting member extending radially inwardly abuts one of the z-filter media construction first flow face or second flow face. 15. An air cleaner comprising: (a) a housing;(b) a primary filter element operably installed within the housing;(c) the primary filter element comprising (i) a z-filter media construction comprising a fluted media secured to a non-fluted media, the z-filter media construction having an first flow face and second flow face, wherein the first flow face and the second flow face are separated from each other in an axial direction;(ii) a frame member mounted on, and secured to, the z-filter media construction and comprising a first radially projecting member and a second radially projecting member, wherein the first radially projecting member and the second radially projecting member are axially spaced apart; and(iii) a seal member including a portion thereof located around the frame member and between the first radially projecting member and the second radially projecting member, and forming a seal with the housing. 16. An air cleaner according to claim 15, further comprising: (a) a pre-cleaner upstream of the primary filter element; the pre-cleaner including multiple centrifugal separators and an ejection tube. 17. An air cleaner according to claim 16, wherein each of the centrifugal separators has a sidewall, an interior volume, and vanes within the interior volume. 18. An air cleaner according to claim 17 wherein: (a) said pre-cleaner comprises: (i) a first tube sheet;(ii) each of the separators being secured to the first tube sheet;(iii) a second tube sheet;(iv) each of the separators including a respective extraction tube integral with the second tube sheet. 19. An air cleaner according to claim 1 wherein: (a) the primary filter element cross-sectional configuration comprises a pair of opposite semicircular ends joined by straight sides. 20. An air cleaner according to claim 15 wherein: (a) the primary filter element includes a non-cylindrical core arrangement within the media construction; the core arrangement having opposing walls. 21. An air cleaner according to claim 20 wherein: (a) the opposing walls of the core arrangement define a socket. 22. An air cleaner according to claim 20 wherein: (a) said core arrangement extends completely between said inlet flow end and said outlet flow end of the primary filter element. 23. An air cleaner according to claim 15, wherein the z-filter media has a racetrack cross-section shape. 24. An air cleaner according to claim 15, wherein the z-filter media construction comprises a wound construction resulting from winding the fluted media secured to the non-fluted media. 25. An air cleaner according to claim 15, wherein the fluted media is secured to the non-fluted media at different locations thereby forming inlet flutes and outlet flutes. 26. An air cleaner according to claim 15, wherein the first flow face and the second flow face are parallel. 27. An air cleaner according to claim 15, wherein the frame member comprises a cross-brace construction located adjacent the first flow face or the second flow face. 28. An air cleaner according to claim 15, wherein the frame member is adhered to an outer periphery of the z-filter media construction. 29. An air cleaner according to claim 15, wherein the seal member is constructed to form an axially directed seal against the housing. 30. An air cleaner according to claim 15, wherein the seal member extends completely, peripherally, around the frame member. 31. An air cleaner according to claim 15, wherein the seal member extends completely, peripherally, around the z-filter media construction. 32.
