A filter assembly including a replaceable filter cartridge for use with a
reusable filter canister. The filter cartridge includes a cylindrical
filter media having top and bottom ends respectively mounted within top
and bottom end caps. The bottom end cap includes a sidewall that
surrounds at least a lower portion of the filter media. A contaminant
containment chamber is defined between the sidewall and an outer side of
the filter media. When the cartridge is mounted within the canister, the
radial sealing element engages an inner surface of the canister to
provide a circumferential seal. The sidewall also includes a living hinge
positioned below the sealing element.
