1. A filter cartridge arrangement comprising: (a) a filter media pack comprising a stacked construction of individual strips of media each comprising a fluted sheet secured to facing sheet to define inlet and outlet flow channels extending between first and second, opposite, flow surfaces;(b) a molded side panel arrangement comprising at least first and second, opposite, molded panels molded directly to, and in sealing coverage over, a first set of two opposite sides of the media pack defined by lead ends and tail ends of the strips of media; and,(c) a housing seal arrangement molded in place on the filter cartridge arrangement;(d) the filter media pack having a second set of two opposites sides each of which is at least partially not covered by the molded side panel arrangement. 2. A filter cartridge arrangement according to claim 1 wherein: (a) the filter media pack second set of two opposite sides is such that each is at least 50% not covered by molded the side panel arrangement. 3. A filter cartridge arrangement according to claim 2 wherein: (a) each media pack side of the second set of two opposite sides is covered by a pre-form sidewall section. 4. A filter cartridge arrangement according to claim 1 wherein: (a) the housing seal arrangement is an integrally molded portion of the molded side panel arrangement. 5. A filter cartridge arrangement according to claim 1 wherein: (a) the housing seal arrangement is not an integrally molded portion of the molded side panel arrangement. 6. A filter cartridge arrangement according to claim 1 wherein: (a) the media pack is a blocked, stacked, construction. 7. A filter cartridge according to claim 1 wherein: (a) the media pack is a slanted, stacked, construction defining at least one oblique parallelogram cross-section. 8. A filter cartridge arrangement according to claim 1 wherein: (a) the housing seal arrangement comprises a single, integrally molded, perimeter seal extension. 9. A filter cartridge according to claim 1 wherein: (a) the housing seal arrangement comprises a plurality of separately molded seal sections. 10. A filter cartridge arrangement according to claim 1 wherein: (a) the molded side panel arrangement comprises two, opposite, molded panels each defining a first edge adjacent the first flow face and a second edge adjacent the second flow face; and,(b) the housing seal arrangement comprises a housing seal perimeter extension recessed from alignment with each edge. 11. A filter cartridge arrangement according to claim 10 wherein: (a) the first and second edges of the two, opposite, molded panels define a projection/recess contour. 12. A filter cartridge arrangement according to claim 11 wherein: (a) the first and second edges each comprise a plurality of projections. 13. A filter cartridge arrangement according to claim 1 wherein: (a) the housing seal arrangement is an axial pinch seal; and,(b) the housing seal arrangement and the molded side panel arrangement each comprise polyurethane. 14. A filter cartridge arrangement according to claim 1 wherein: (a) the housing seal arrangement and the molded side panel arrangement each comprise foamed polyurethane having an as-molded density of no greater than 30 lbs/cu.ft. 15. An air cleaner comprising: (a) a housing having an inlet section and an outer section; and,(b) a filter cartridge arrangement comprising: (i) a filter media pack comprising a stacked construction of individual strips of media each comprising a fluted sheet secured to facing sheet to define inlet and outlet flow channels extending between first and second, opposite, flow surfaces;(ii) a molded side panel arrangement comprising at least first and second, opposite, molded panels molded directly to, and in sealing coverage over, a first set of two opposite sides of the media pack defined by lead ends and tail ends of the strips of media; and,(iii) a housing seal arrangement molded-in-place on the filter cartridge arrangement;(iv) the filter media pack having a second set of two opposite sides each of which is at least partially not covered by the molded side panel arrangement. 16. An air cleaner according to claim 15 wherein: (a) the outlet section is selectively rotationally pivotable relative to the inlet section to release sealing pressure on the housing seal arrangement. 17. An air cleaner according to claim 15 wherein: (a) the filter cartridge is removably positioned within a preformed cassette; and,(b) the filter cartridge and cassette are positioned within the housing with the housing seal member pinched between a flange on the cassette and a portion of the housing. 18. A filter cartridge arrangement comprising: (a) a filter media pack comprising a stacked construction of individual strips of media each comprising a fluted sheet secured to facing sheet to define inlet and outlet flow channels extending between first and second, opposite, flow surfaces;(b) a molded side panel arrangement comprising at least first and second, opposite, molded panels molded directly to, and in sealing coverage over, a first set of two opposite sides of the media pack defined by lead ends and tail ends of the strips of media; (i) the molded side panel arrangement comprising two, opposite, molded panels each defining a first edge adjacent the first flow face and a second edge adjacent the second flow face; and,(ii) the first and second edges of the two, opposite, molded panels defining a projection/recess contour; and,(c) a housing seal arrangement molded in place on the filter cartridge arrangement; (i) the housing seal arrangement comprising a housing seal perimeter extension recessed from alignment with each edge.
