NANOFIBER FILTER WRAPS

A nanofiber filter wrap is a filter element comprising a polymer film including a first surface, a second surface opposite the first surface, an array of nanofibers extending from the first surface, a first end, a second end opposite the first end, and opposing first and second edges extending from the first end to the second end. The polymer film is wound or folded to form a plurality of spaced adjacent layers defining interlayer gaps extending through the filter element from the first edge to the second edge substantially normal to a basal plane defined by the second edge of the polymer film. A fluid flowed can be flowed through the interlayer gaps to contact at least a portion of the array of nanofibers whereby a contaminant contained in the fluid is at least partially filtered from the fluid.
