Abstract
A filter media comprises a medium for capturing and neutralizing harmful substances. Methods for fabricating a low-pressure, high efficiency filter media for capturing harmful substances produce filter media having engineered pores that have an engineered pour size dispersion, which may be monodispersed and uniformly arranged. Neutralizing components may be coated on filter media, providing both increased capture efficiency and neutralization of at least one harmful substance, such as harmful pathogens, aerosols, particulates, VOCs, gases and vapors.
