A filter assembly includes a housing and filter elements. The housing includes internal chambers between first and second parallel outside surfaces, fluid inlet bores, and fluid outlet bores. Each internal chamber includes a filter element that partitions the internal chamber into an inlet chamber section and an outlet chamber section. The housing establishes a plurality of fluid flow channels from the inlet bores, through the inlet chamber sections, through the filter elements, through the outlet chamber sections and to the outlet bores, respectively. Each fluid channel includes a transverse fluid flow component in the inlet chamber section and the outlet chamber section. The filter assembly may be loaded into a filtering apparatus such that a plurality of separate fluid flow channels is established through the filter assembly. Fluid may be flowed through two or more of the fluid flow channels, wherein the fluid in each of the two or more fluid flow channels passes through the respective filter element and is filtered thereby.
