Abstract
A filter device is disclosed. The device includes at least one substantially flat filter media that may be encapsulated between non-permeable films. Some embodiments comprise ports for introducing a fluid to be filtered and for evacuating the filtered fluid. Various substrates may be employed therein in cooperation with the at least one filter media to enhance device performance. Also disclosed are various apparatuses configured to contain at least one filter device.
Claims12
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.
