1. A filter cartridge for insertion into a housing for an air cleaner assembly, the filter cartridge comprising:
a) a media pack extending along a longitudinal axis between opposite first and second flow ends, the media pack having opposite first and second long sides and having opposite first and second short sides;
b) a seal member presenting a seal surface facing in a radial direction for sealing against a housing surface facing in a radial inward direction; and
c) a first radially facing contact surface located along the media pack first long side and a second radially facing contact surface located along the media pack second long side, the first and second radially facing contact surfaces being separate from the seal member and located proximate the seal member and configured for engaging with the housing to constrain deflection of the housing in a radial direction away from the seal member.
