A filtration device including a contoured support having 1) an interior surface, 2) an outside peripheral surface spaced farther from a center of the contoured support than the interior surface, and 3) a rim enclosed and sealed to a perimeter of the contoured support. The filtration device includes macroscopic openings in the contoured support extending from the interior surface to the outside peripheral surface, and a plurality of nanofibers having diameters less than 1 micron. The nanofibers are disposed on the outside peripheral surface of the contoured support, and cover the macroscopic openings to form a filtration medium on the contoured support.
