Water Factor (WF)

Water Factor, or WF, is the water performance metric that allows the comparison of clothes washer water consumption independent of clothes washer capacity. The lower the value, the more water efficient the clothes washer is. To find your clothes washer's WF, go to the ENERGY STAR® website.
