A filter assembly (110) includes a filter vessel (112) having an inlet (114), an outlet (116), and defining a filter chamber (118) therebetween. A basket assembly (124) is removably supported within said filter chamber (118) and has a diameter less than the diameter of the filter chamber (118) so as to define an annular flow path (128) about the basket assembly (124). The basket assembly (124) includes an outer, permeable member (130) and an inner, permeable member (132) having a diameter which is less than the diameter of the outer, permeable member (130) so as to define an annular space (136) therebetween and an inner flow path (C). The basket assembly (124) supports a bag-type filter (142) over both the inner and outer permeable members (130, 132) bounding the annular space (136) therebetween. The bag-type filter (142) includes a first portion (144) having a first, larger diameter and a second portion (146) having a second, reduced diameter. A transition portion (148) is disposed between the first and second portions (144, 146) of the bag-type filter (142).
