Method of manufacturing filter elements for fluid filters, consisting essentially of a strip of filter paper of convenient length, zig-zag folded transversely, which is then rolled to determine a tubular body in which those folds are arranged longitudinally and parallel to each other, a process then to treat the tubular body formed by immersion in a bath of a chemical material such as a resin that increases its rigidity and decreases the natural porosity of the paper, then going to assemble said tubular element through the arrangement of a helical spring adjusted to its inner diameter, thus providing it with precise deformability against the pressures of the fluids to be filtered, after which the ends of the tubular body thus formed and assembled are closed by means of circular ring-shaped pieces, which adhere on the chemically treated filter paper to tr thanks to a suitable glue, the filtering element is finished in this way.
