A filter device has two flow paths. The first flow path has at least one cap and fluid port. The second flow path surrounds the first fluid flow path and has at least one cap that overlaps the cap of the first fluid flow path. The second flow path also has at least one fluid port. The filter device provides a simple arrangement that is easily disinfected or sterilized.

[ What is claimed is:] [34.] A method of filtering a fluid comprising the step of providing a filter device comprising a housing, a first fluid flow path contained in said housing, a molding compound adjacent the ends of the first fluid flow path, a first fluid port for fluid inflow and outflow from said first fluid flow path, a first cap joined to said molding compound and the first fluid port, a second cap connected to said housing and overlapping said first cap, a second fluid flow path between said first and second caps and in a space between the housing and the first fluid flow path, a second fluid port providing fluid inflow and outflow from the second fluid flow path, a ring having projections and having axial notches in fluid communication with said second fluid flow path, and further comprising the steps of flowing a first fluid through the first fluid flow path and flowing a second fluid through the second fluid flow path, impurities from said first fluid diffusing into and said second fluid, said second fluid with said impurities flowing out of said second fluid flow path through said second fluid port.
