A porous membrane may have a high concentration of spherical fillers with a polymer binder. The polymer binder may have an affinity for the filler materials and may hold the filler materials together in a porous structure with high tortuosity and consistent pore size. The membrane may be manufactured with a reinforcing web, such as non- woven web. The membrane may be greater than 50% porous with a less than 1 micron pore size. Within the pore walls that may be less than 0.02 microns in width, a densely packed filler material may have an average diameter of less than 0.005 microns.
