A fluid filter having a hollow, molded, plastic housing with an open end, a fluid inlet port and a fluid outlet. An internally threaded, plastic, molded cap is threadedly received on the housing via mating external threads for sealing the open end of the housing. A cap seal prevents fluid contamination of the threads. A removable filter element is contained within the housing between the fluid inlet and the fluid outlet. A molded, resilient, plastic retainer captured between the cap and the filter element retains the filter element in position within the filter. If the filter element is of a bag filter type, as compared with a filter cartridge type, the retainer has a plurality of resilient legs which press down upon a bag mouth seal forcing it into contact with a flared mouth of the bag support.

A filter for filtering fluids, comprising: a) a hollow having an open end, a fluid inlet and a fluid outlet; b) a cap removably received on said housing for sealing said open end thereof; c) a removable filter element contained within said housing between said fluid inlet and said fluid outlet; and d) a resilient retainer compressed between said cap and said filter element for retaining said filter element in position within said filter, said retainer including a hub positioned above said filter element such that said hub is movable toward said filter element in response to the application of said cap to said housing, a ring positioned in abutment with said filter element, and a plurality of resilient legs extending between said hub and ring, each of said legs being deformable in response to the movement of said hub toward said ring, whereby said legs inhibit said retainer from applying excess compressive forces against said filter element as said cap is applied to said housing.
