Abstract
A filter media that inhibits the formation of static charge in a liquid flowing through the filter media comprises a filtration layer having a first surface and a second surface opposite the first surface and comprising a non-conductive fibrous material having a plurality of fibers, the fibrous material comprising a metal layer deposited on at least a portion of the fibers through at least a portion of the thickness of the filtration layer. The filter media or a filter apparatus incorporating the filter media does not require means for dissipating static charge from the fluid and, therefore, does not require grounding.
