A method of manufacturing an enhanced porous ceramic article includes the steps of: impregnating (a) a porous ceramic body, (b) a first porous body having one or more dried layers of porous ceramic films on a surface of a porous ceramic body, or (c) a second porous body having one or more dried-fired layers of porous ceramic films on a surface of a porous ceramic body, with inorganic oxide sol; sending air to a desired portion of the porous ceramic body and/or the porous ceramic films to aggregating and drying inorganic oxide particles in the inorganic oxide sol inside a surface of the desired portion; and thereafter firing the body or the body with the film to obtain the enhanced porous ceramic article. The manufacturing method is capable of substantially uniformly aggregating and supporting inorganic oxide such as silica in a desired portion of the porous ceramic article for use in a ceramic filter or the like.
