<p>A filtering device (100), allowing to provide an effective filtering without either requiring particular efforts to the user or imposing him or her to operate in excessively hard positions, comprises a filtering element (2) comprised between a first and a second supporting surface (11, 12), the distance between the supporting surfaces (11, 12) being adjustable, so as to compress the filtering element (2) by moving said supporting surfaces (11, 12) the nearer the other, and actuating means (3) apt to modify the distance of the supporting surfaces (11, 12). The actuating means (3) are selectively connectable to a surface (12) of the supporting surfaces (11, 12) in a such way that the actuating means (3) can alternatively move unrelated to motion of the surfaces (11, 12) so as to be placed in an operative configuration or move integral to the surface (12) so as to modify the distance between the surfaces (11, 12) in order to compress the filtering element (2).</p> |
