Filters for removal of pathogens from liquids

The present invention relates to filters capable of removing various contaminants, including pathogens, from liquids by filtration. In particular, it relates to filters that comprise activated carbon fibers for removing a broad spectrum of contaminants, including viruses, from liquids. Additionally, it relates to a method of removing contaminants from liquids. A process for forming an activated carbon fiber filter for removing viruses from liquids is provided. The process includes selecting a plurality of activated carbon fibers, placing the activated carbon fibers in a hollow form open at least one end, and applying a predetermined compressive force to the fibers along the axis through the hollow form parallel to the direction in which the liquid will pass until the fibers are densely and uniformly packed within the form.
