<p>A filter element (14, 214, 314) includes outer and inner sleeves (16, 18, 216, 218, 316, 318) made from a flexible, pervious material. The inner sleeve (18, 218, 318), which is arranged substantially concentric with respect to the outer sleeve (16, 216, 316), employs one or more handles (50, 52, 225, 227, 337) to facilitate the removal of the filter element (14, 214, 314) from an associated filter housing.
