Abstract
A blood filter unit comprising an assembly for supporting a filter cartridge, a filter cartridge, and a housing for the assembly and cartridge. The assembly for supporting the cartridge comprises a permeable cylindrical core with a bottom member and a top cap. The filter media, in the form of a cartridge, is disposed about the periphery of the core and extends between the bottom member and top cap. The core contacts the media only at intermittent areas spaced longitudinally and circumferentially about the core. The core, media and walls of the housing are tapered with respect to each other.
