The present invention is a fluid flow fibrous structure, wherein the fluid flow is a mixture of nano-alumina fibers and second fibers arranged in a matrix to produce asymmetric pores, Without using a binder, fine particles such as powdered activated carbon, ultrafine particles or nano-sized particles are attached. A fiber structure containing powdered activated carbon prevents contaminants from the fluid stream. The present invention is also a method of manufacturing and using a fibrous structure.
