A filter element assembly has at least two cylindrically shaped and concentrically arranged flexible filter media sleeves each connected at one end thereof to an inlet plate and each connected at the other end to a closed end plate. Openings are provided in the inlet plate to permit entry of liquid to be filtered into the annular space between the filter sleeves. The closed end plate prevents flow of unfiltered liquid from the annular space between the sleeves so as to force the liquid through the porous media of the sleeves to effect filtration. Each of the filter sleeves is supported by a rigid, cylindrically shaped mesh screen of an annularly shaped basket.
