Abstract: The water-saving nozzle has an outer housing that includes an outer vortex screw in operative engagement with an inner housing that is disposed inside the outer housing. The vortex screw has helical threads. The inner housing has an inner vortex screw with outside helical threads. When water passes through the outer and inner vortex screws the water is rotated before the water passes into the vortex chambers of the inner and outer housings. The water discharged from the outer housing forms an outer dome shape and the water discharged from the inner housing forms an inner dome shape inside the outer dome shape.

Abstract: The method is for discharging water through a faucet. The nozzle is attachable to a faucet and switchable between a spray-mode and a mist-mode. An inner cavity has filters and a water rotating device. The housing has an opening defined therein in fluid communication with the inner cavity and grooves and an orifice at a bottom portion thereof. The second filter is disposed below the opening. When in the spray-mode, water flows out through the opening and through grooves and is discharged as spray and mist at a bottom of nozzle. When switched to the mist mode, water only flow through the second filter but not through the opening. Water flows through the water rotating device to create a rotation of the water and the rotating water is discharged through the orifice as mist.
