Abstract: A filtering device including a casing with an inlet space for liquid to be filtered and an outlet space for filtered liquid; a substantially cylindrical filtering element of the disposable type, which is removably placed within the casing to function therein as a liquid permeable partition between the inlet space and the outlet space; a unique information containing micro circuit or chip provided in the filtering element, adapted to function as an identification label and cooperating with a receiver provided in the casing, so as to provide for a periodical or continuous exchange of information between the micro circuit and the receiver. The micro circuit is embedded, at a circumferential location, in an annular seal provided at a terminal edge of the cylindrical filtering element, the seal enabling the filtering element to sealingly engage an annular seat between the inlet space and the outlet space.
