Abstract: A disposable filter cartridge, in which the entire filter cartridge is disposable. The filter cartridge includes a tubular filter element substantially permanently retained to a lid such that the filter element cannot be removed from the lid without extreme force. The filter element includes a ring of filter media having ends potted in cup shaped end caps. The lid includes a central hub that is inserted through the opening in on of the end caps and ultrasonically deformed or flared radially outward to provide a lip that engages the top end cap for axial retention. The filter element is free floating and can be moved or tilted a small degree axially and can also be freely rotated relative to the lid.
