High-Efficiency Clothes Washers (HEWs)
The water efficiency of clothes washers is rated using the term "water factor" to describe and compare its water use. Water factor (WF) is measured by the quantity of water (gallons) used to wash each cubic foot of laundry. A lower water factor represents greater water and energy efficiency.
