A fluid filter is provided with a snap-together housing for the filter media. The housing is designed with two main parts that are easily snapped together to encapsulate the filter media. The filter housing is substantially cylindrical, and contains an inlet on one end of the filter and an outlet on the opposing end. The filter can be designed so as to be opened for the replacement of the filter media.

The invention claimed is: 1. A tamper resistant, snap-together, filter housing which can be easily assembled, but which can not be easily disassembled without special tools or knowledge to apply inwardly directed pressure to at least one portion of the filter housing. 2. A two-part snap-together filter housing to hold a filter in a pinch seal for leukocyte reduction which can be easily assembled, but which cannot be easily disassembled without the special tools or knowledge to apply inwardly directed pressure to at least one part of the two-part filter housing. 3. A snap-together, multi-part, filter housing to hold a filter in a pinch seal comprising a continuous outer wall and having connectors to connect the housing parts together which can easily be assembled, but which cannot be easily disassembled without special tools, wherein the connectors are primarily inside the outer periphery of the multi-part filter housing, and at least a portion of the connectors comprise openings in the continuous outer wall of the multi-part filter housing. 4. A tamper resistant filter comprising: (a) a hydrophilic flat filter media, and (b) a housing for said tamper resistant filter comprising two main sections which can be easily snapped together around said filter media to hold said filter media in a pinch seal between said two main sections, but which can not be disassembled without special tools. 5. A snap-together, multi-part, filter housing which holds a filter in a pinch seal within the filter housing, comprising a continuous outer wall and having connectors to connect the housing parts together which can easily be assembled, but which cannot be easily disassembled without special tools, wherein the connectors are primarily outside the outer periphery of the multi-part filter housing, and at least a portion of the connectors comprise openings in the continuous outer wall of the multi-part filter housing. 6. A two-part snap-together filter housing comprising a first housing section having a first outer peripheral wall, and a ring projecting outwardly from the first outer peripheral wall, the ring having a plurality of projecting portions, each of said projecting portions having a notch extending therethrough, and a second housing section having a second outer peripheral wall, with a plurality of tabs corresponding to the notches, wherein the second housing section will be an exterior wall when the two-part filter housing is assembled, the peripheral wall of the second housing section will cover the peripheral wall of the first housing section, and the tabs will engage the notches without extending therethrough, thereby fastening the two halves of the filter housing together. 7. A two-part snap-together filter housing comprising a first housing section having a first peripheral wall, and a plurality of tabs protruding substantially radially outward from the first peripheral wall, and a second housing section having a second peripheral wall of substantially the same length as the first peripheral wall, wherein the second housing portion will form the exterior wall when the two-part filter housing is assembled, and has a plurality of notches extending through the second peripheral wall corresponding to the tabs on the first peripheral wall, and wherein the tabs will engage the notches without extending therethrough, thereby fastening the first housing section and the second housing section of the two-part filter housing together, with the first peripheral wall covered by the second peripheral wall, thereby holding a filter in a pinch seal between the first housing section and the second housing section.
