1. An air filter cartridge for removable installation in an air cleaner housing; the air filter cartridge comprising: (a) a media pack comprising filter media including fluted media secured to facing media to define opposite inlet and outlet flow faces with flutes extending therebetween, the opposite inlet and outlet flow faces corresponding to opposite ends of the media pack; (i) the media pack being configured so that air cannot pass from the inlet flow face to the outlet flow face without filtering flow through the media; and,(ii) the media pack having at least first and second, opposite, sides extending between the opposite ends of the media pack; and,(b) a housing seal member;(c) the air filter cartridge including first and second opposite sides; (i) a first member of a first projection/receiver arrangement positioned on the first side of the air filter cartridge in overlap with one of the first and second, opposite, sides, of the media pack and spaced from the housing seal member; the first member of the first projection receiver arrangement being oriented for engagement with a second member of the first projection/receiver arrangement positioned in the air cleaner housing, in use;(ii) the first member of a first projection/receiver arrangement comprising at least first and second sides that diverge from one another; the first and second sides of the first member each being positioned in overlap with one of the first and second opposite sides of the media pack. 2. An air filter cartridge according to claim 1 wherein: (a) the first member of the first projection/receiver arrangement on the first side of the air filter cartridge has a shape with a central vertex and opposite sides. 3. An air filter cartridge according to claim 1 including: (a) a preform having first and second opposite sides with: (i) the first side of the preform including the first member of the first projection/receiver arrangement molded as part of the preform. 4. An air filter cartridge according to claim 3 wherein: (a) the preform surrounds the media pack. 5. An air filter cartridge according to claim 4 wherein: (a) the preform completely contains the media pack. 6. An air filter cartridge according claim 3 wherein: (a) the first member of the first projection/receiver arrangement on the first side of the preform has a shape with a central vertex and opposite sides. 7. An air filter cartridge according to claim 2 wherein: (a) the vertex of the first member of the first projection/receiver arrangement is directed toward an end of the filter cartridge and also toward the housing seal member. 8. An air filter cartridge according to claim 1 wherein: (a) the first member of the first projection/receiver arrangement has opposite sides with an angle between them within the range of 25°-60°, inclusive. 9. An air filter cartridge according to claim 1 wherein: (a) the air filter cartridge includes a grid extending across an end of the air filter cartridge. 10. An air filter cartridge according to claim 1 wherein: (a) the housing seal member comprises a perimeter seal member. 11. An air filter cartridge according to claim 1 wherein: (a) the media pack comprises a stack of strips of fluted sheet secured to facing sheet. 12. An air filter cartridge according to claim 1 wherein: (a) the media pack is a slanted, stacked, media pack. 13. An air filter cartridge according to claim 1 wherein: (a) the media pack is a blocked, stacked, media pack. 14. An air filter cartridge according to claim 1 wherein: (a) the first member of the first projection/receiver arrangement is a receiver member. 15. An air filter cartridge according to claim 1 wherein: (a) the housing seal member includes a central region and at least one flexible lip member positioned and configured to flex toward the central region when forming a seal against the air cleaner housing. 16. An air cleaner comprising: (a) a removable and replaceable air filter cartridge including: a media pack; and, a housing seal member; the air filter cartridge having first and second opposite sides; (i) the media pack comprising fluted filter media secured to facing filter media to define inlet and outlet flow faces with flutes extending therebetween, the opposite inlet and outlet flow faces corresponding to opposite ends of the media pack; (A) the media pack being configured so that air cannot pass from the inlet flow face to the outlet flow face without filtering flow through the media; and(B) the media pack having at least first and second, opposite, sides extending between the opposite ends of the media pack; and,(ii) a first member of a first projection/receiver arrangement positioned on the first side of the air filter cartridge spaced from the housing seal member; and in overlap with one of the first and second, opposite, sides, of the media pack; the first member of the first projection receiver arrangement being in engagement with a second member, of the first projection/receiver arrangement, positioned in the air cleaner housing,(b) a housing having: an inlet and an outlet; an interior; and, opposite first and second sides; (i) the first side of the housing having an interior with a second member of the first projection/receiver arrangement thereon; and,(c) the air filter cartridge being removeably positioned within the interior of the housing: (i) between the inlet and outlet;(ii) with the housing seal member sealed against the housing; and,(iii) with the first member of the first projection/receiver arrangement on the first side of the air filter cartridge engaged with the second member of the first projection/receiver arrangement on the first side of the housing. 17. An air cleaner according to claim 16 wherein: (a) the first member of the first projection/receiver arrangement has a central vertex and opposite sides; and,(b) the second member of the first projection/receiver arrangement has a central vertex and opposite sides. 18. An air cleaner according to claim 16 wherein: (a) the air filter cartridge includes a preform having first and second opposite sides; (i) a first side of the preform including the first member of the first projection/receiver arrangement molded as part of the preform. 19. An air cleaner according to claim 16 wherein: (a) the first member of the first projection/receiver arrangement has a vertex pointing toward an end of the filter cartridge and the housing seal member. 20. An air cleaner according to claim 16 wherein: (a) the housing seal member includes a central region and at least one flexible lip member position and configured to flex toward the central region when forming a seal against the air cleaner housing. 21. An air cleaner according to claim 16 wherein: (a) the first member of the first projection/receiver arrangement is a receiver member. 22. An air cleaner according to claim 16 wherein: (a) the first and second sides, of the first member of the first projection/receiver arrangement, extend non-perpendicularly to one another. 23. An air cleaner according to claim 16 wherein: (a) the first and second sides, of the first member of the first projection/receiver arrangement, have side faces that face one another. 24. An air cleaner according to claim 16 wherein: (a) the first and second sides, of the first member at a first projection/receiver arrangement, extend at a non-right angle to a plane defined by at least one of the inlet flow face and outlet flow face. 25.
