My invention comprises a two element filter bag which includes a cylindrical outer element, a generally tubular inner element, a joining means, a securing means, and a diverting means. Cylindrical outer element is hollow, constructed of suitable filter media, and has first and second open ends. Tubular inner element is also hollow, constructed of suitable filter media, and has one closed end and one open end. Tubular inner element is positioned within cylindrical outer element so that the first open end of the outer element is generally coplanar with the closed end of the inner element, and the second open end of the outer element is generally coplanar with the open end of the inner element. Joining means joins the second open end of the outer element to the open end of the inner element. Supporting means is positioned within the inner element through open inner element end and provides support to inner element. Diverting means uniformly diverts the process flow entering the filter bag through first open outer element end throughout the interior of the filter bag. Preferably, diverting means comprises a cone shaped inner element closed end. Process flow is filtered by the filter bag when the flow collides with and permeates through the inside surface of the outer element and the outside surface of the inner element.
