Improvements introduced in the press filters, which are characterized in forming the filtering unit by the superposition of several plates made of elastic material in whose faces a series of parallel grooves are practiced that cover the entire surface except for a peripheral area that is flat and constitutes the place of application of each two adjacent plates, interposed between each two plates, a sheet of filtering material that covers the plate completely and is compressed in its entirety by the peripheral zone, and partially in the central area between the ridges of the fluted.
