The present invention relates to a device especially contrived for providing a considerably water consumption savings, the device of the invention being formed from a tubular main metal body (1) wherein there is defined a lower neck (11) with a smaller diameter open at the lower portion, also having an upper threading (13) for being coupled to the corresponding tap. A purifying filter (3) is arranged in the centre of the main body, encircling a plastic drum (4) provided with grooves (15) for the passage of water, in which centre a plastic screw (5) is inserted with the interposition of a rubber washer (6), such that the lower neck (11) of the main metal body (1) is connected to a metal outer part (9), open at the lower portion, through which the reduced water flow finally exits. The device can be made according to two embodiments, in one of which the outgoing water flow is manually adjustable.
