Replaceable element for fluid filters, consisting essentially of a tubular body of filter paper treated with a chemical material that provides greater rigidity and reduces its natural porosity, whose body is provided with a series of accordion-shaped pleats on its entire surface , which in this way increases considerably, being arranged between two test pieces in the form of circular crowns, adhered thereto through a suitable glue, while inside the body is arranged a frame constituted by a helical spring adapted to its inner diameter and that communicates the necessary indeformability against the pressures of the fluid to filter.
