Normal standard aerators consume about 3.5 gallons of water per minute. The WOLF eco aerators consume only 1 gallon water per minute, yet offer the same stream volume, achieved by the effective implementation of the air sputtering system in the WOLF eco aerators.

A useful side-effect: is that the air proportion in the water is higher, resulting in much less ricocheting off your hands when than with nonstandard aerators - the hands get wet, the bathroom stays dry !
