High performance filters based on inorganic fibers and inorganic fiber whiskers
First Claim
1. An activated, high surface area filter media including a structure capable of microfiltration and adsorption, the filter media comprising a blend of activated carbon containing inorganic fibers, inorganic fiber whiskers and a binder, wherein the filter media has an interconnected porosity that is adapted to allow fluid to flow through the filter media, and a pore size distribution that is adapted to capture particles having a diameter in the range of about 0.1 to about 100 microns.

Abstract
A filter media structure, which is capable of operating in the micro- and nanofiltration regime, offers: low cost, durability, high temperature and chemical resistance, high permeability, high flow rate, low pressure drop across the filter media, high mechanical strength, separation efficiency, and biocompatibility. The filter media structure is comprised of blend of carbon or ceramic fibers and inorganic fiber whiskers generally having a diameter of from about 0.03 to about 5 microns. In one embodiment, filter media structure is comprised of blend of activated carbon-containing inorganic fibers and inorganic fiber whiskers generally having a diameter of from about 0.03 to about 5 microns.
