摘要： A filter, system and method is provided for filtering nanoparticles in a hot gas, namely particles about 200° C. and further particularly >about 450° C. including diesel exhaust. The filter includes filter media material composed of fibrous filter media having a plurality of fibers and granular filter media having a plurality of granules extending from the surfaces of the fibers. The filter is characterized by a permeability >about 3×10−12 m2 and an inertial resistance coefficient
