Abstract:
1. A filter device comprising: a first non-permeable film comprising a first fluid communication port to create an inlet fluid connection therethrough to an inlet chamber; a second non-permeable film comprising a second fluid communication port to create an outlet fluid connection therethrough to an outlet chamber; a filter element planarly encapsulated by the first and second non-permeable films, the filter element comprising a filter media comprising a first surface facing the outlet chamber, a second surface facing the inlet chamber, a first end, a second end, and a plurality of planarly disposed pleats; and a framing substrate attached to the filter element, the first non-permeable film, and the second non-permeable film; wherein at least one of the first non-permeable film or second non-permeable film comprises multiple fluid communication ports; and wherein the first surface of the first end is attached to the framing substrate which is attached to the first non-permeable film, thereby putting the second surface of the first end in contact with the first non-permeable film, and wherein the first surface of the second end is attached to the framing substrate which is attached to the second non-permeable film thereby putting the second surface of the second end of the filter media in a compressible state against the framing substrate upon flow of fluid into the inlet chamber.
