ABSTRACT:
A filter for fluids includes a pair of layers or multiple layers or pairs of material joined together to form a laminate having a fluid contacting surface. A plurality of spaced pockets is formed between the layers of material in the contacting surface. The layers of material are fluid permeable at the pockets whereby fluid may flow through the laminate at the pockets. The fluid contacting surface is fluid impermeable except for the pockets to require the fluid passing through the laminate to be confined to flowing through the pockets. Filter members are in the pockets for removing any contaminants from the fluid. Alternatively, additive materials such as powdered cream or sugar in the pockets dissolve in the fluid passing through the pockets to enhance the fluid.
