Abstract: A filtration device including a base filtration material having openings for fluid flow there through and a filtration medium. The filtration medium includes a plurality of patterned nanofibers formed on the base filtration material. The filtration medium has a figure of merit greater than 30 kPa−1, where the figure of merit is given by −Log (Pt)/ΔP, where Pt is the fractional penetration of a specific aerosol particle diameter and ΔP is a pressure drop across the filtration medium corresponding to a face velocity of 5.3 cm/s and particle size of 0.3 microns.
