Abstract
A filtering device, 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 comprised between a first and a second supporting surface, the distance between the supporting surfaces being adjustable, so as to compress the filtering element by moving the supporting surfaces the nearer the other, and actuating device apt to modify the distance of the supporting surfaces. The actuating device is selectively connectable to a surface of the supporting surfaces in a such way that the actuating device can alternatively move unrelated to motion of the surfaces so as to be placed in an operative configuration or move integral to the surface so as to modify the distance between the surfaces in order to compress the filtering element.
