  • Fluid filter and method of making same
    Patent number: 4066556
    Abstract: A fluid filter assembly is comprised of a flexible, compressible housing, a filter pouch in the housing formed from membrane filter media and having a fluid opening in one end thereof, a fluid inlet extending into the housing in fluid communication with the interior of the filter pouch through the fluid opening, and a fluid outlet extending from the housing in fluid communication with the interior of the housing external of the filter pouch. Fluid may pass through the fluid inlet into the interior of the filter pouch, then pass through the membrane filter media of the filter pouch into the interior of the housing external of the filter pouch and finally exit from the housing through the fluid outlet. The unique filter pouch may be made by providing a filter sheet of membrane filter media and folding the sheet substantially in half to form a filter pouch configuration having a folded edge, two edges adjacent the folded edge and an edge opposite the folded edge.
