1. An air filter cartridge comprising:
(a) a filter media pack comprising filter media and having an air inlet flow face and an air outlet flow face opposite the air inlet flow face, and a central flow axis through the air inlet flow face and the air outlet flow face;
(i) the filter media pack having a rectangular cross-sectional shape in a direction perpendicular to the central flow axis; and
(ii) the filter media pack comprising four sides, including a first pair of first and second opposite sides and a second pair of first and second opposite sides, extending between the air inlet flow face and the air outlet flow face;
(b) first and second side pieces positioned on the first pair of first and second opposite sides of the filter media pack, respectively, wherein:
(i) the first and second side pieces each comprise a surface spaced from the air outlet flow face of the filter media pack in a direction away from the air inlet flow face of the filter media pack; and
(ii) the first and second side pieces being configured to seal the first pair of first and second opposite sides of the filter media pack against air flow through the first pair of first and second opposite sides of the filter media pack along the central flow axis; and
(c) a housing seal arrangement for sealing the air filter cartridge to an air cleaner housing, in use, wherein:
(i) the housing seal arrangement comprises a seal member that forms a pinch seal between housing pieces, in use; and
(ii) the seal member extends across the first and second side pieces so that the seal member extending across the first and second side pieces is arranged in a plane that is non-parallel to a plane perpendicular to the central flow axis.
