Flat, stackable filter disk elements include a deep bed filter material for removing particulates from a flow of unfiltered fluid and thereby obtain a filtered fluid. The filter material has a thickness extending between a pair of major parallel planar surfaces which define a filter element plane, and include a first flow openings for the filtered fluid, a second flow opening for unfiltered fluid, and a collection opening for collecting one of the filtered and unfiltered fluids. The collection opening and the first and second flow openings extend through the filter material between the planar surfaces. The first and second flow openings also respectively define first and second flow surfaces for the filtered and unfiltered fluids which are substantially perpendicular to the filter element plane and which establish a fluid flow path between the first and second flow openings through the filter material which is substantially parallel to the filter element plane. Each of the first and second flow openings includes an open end and a closed end, wherein open ends of one of the first and second flow openings being connected to the collection opening, and open ends of the other of the first and second flow openings being unconnected to the collection opening. The boundary surfaces of the first and second flow openings define the flow surfaces for the filtered and unfiltered material, respectively. Most preferably, each of the first and second flow openings include a stiffening bridge disposed between the open and closed ends thereof that extends across a width dimension of the respective first and second flow openings and across at least a portion of a thickness of the filter material and depth of the respective first and second flow openings.
