Purchasing Tips

Ask for ENERGY STAR®. When buying a clothes washer, request an ENERGY STAR® qualified model to ensure that it is energy-efficient.

Check the yellow EnergyGuide label:energyguide_tag_washer
This label helps to:

  1. determine how much energy the model uses
  2. compare the energy use of similar models, and
  3. estimate annual operating costs.

Choose a size that meets your household needs. ENERGY STAR® qualified clothes washers are available in many sizes, ranging in capacity from 1.6 to 3.8 cubic feet. ENERGY STAR® qualified models are also available in stackable and under-the-counter designs, which fit in smaller spaces.

Choose a model with a high Modified Energy Factor (MEF) and a low Water Factor (WF). Modified Energy Factor (MEF) is a comprehensive measure of energy efficiency that considers the energy used by the washer, the energy used to heat the water, and the energy used to run the dryer. The higher the MEF, the more efficient the clothes washer. Water Factor (WF) measures the water efficiency and is calculated as gallons of water consumed per cubic foot of capacity. The lower the WF, the more efficient the clothes washer. Both MEF and WF are listed on the ENERGY STAR® qualified product list:

Look for several water level options. Choose a washing machine that has several options for adjusting the water level to fit the load.
