A filter capable of being cleaned by reverse flushing, comprises a housing including a fluid inlet, a fluid outlet, a flushing outlet, and a filter body disposed within the housing. The housing includes blocking members disposed on opposite faces of the filter body and axially spaced from each other to define a reverse flushing passageway from the fluid inlet to the flushing outlet through the portion of the filter body between the axially-spaced blocking members. At least one of the blocking members is movable axially of the filter body to reversely-flush the complete length of the filter body.
