Abstract: A filter including a first flow face extending along a lateral direction and a transverse direction of the filter, wherein the first flow face includes at least one contaminant retention layer first edge and at least one flow defining layer first edge, a second flow face spaced in an axial direction from the first flow face, wherein the second flow face extends along the length and the width of the filter and includes at least one contaminant retention layer second edge and at least one flow defining layer second edge, at least one contaminant retention layer extending from the contaminant layer first edge to the contaminant layer second edge, and at least one flow defining layer adjacent to at least one of the contaminant retention layers, the at least one flow defining layer extending from the flow defining layer first edge to the flow defining layer second edge, wherein at least one of the flow defining layers defines at least one fluid flow path in the axial direction as fluid moves from the first flow face toward the second flow face.
