Air cleaner assemblies and methods of use

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 inlet and outlet 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 for sealing against a housing surface, the seal member being located proximate a first end of the filter cartridge;
• c) a handle member located proximate the first end of the filter cartridge;
• d) 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 located proximate the first end of the filter cartridge and configured for engaging with the housing to constrain deflection of the housing in a radial direction away from the seal member;
• and
• e) a shell at least partially surrounding the media pack, wherein the first and second radially facing contact surfaces are formed as part of the shell.

A filter cartridge for insertion into a housing of an air cleaner assembly, the filter cartridge comprising:

• a) a media pack extending along a longitudinal axis between opposite inlet and outlet 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 outward direction for sealing against a housing surface facing in a radial inward direction, the seal surface deviating in an axial direction at a location along the media pack first and second short sides;
• 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 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.
