Question:

What are MEF and WF ratings on washing machines?

Answer:

MEF and WF ratings are two important factors that determine the energy and water efficiency of a washing machine.

MEF stands for Modified Energy Factor. This rating measures how efficiently a washing machine uses energy during the wash cycle. A higher MEF number indicates better energy efficiency.

WF or WF (WCF) stands for Water Factor/Water Consumption Factor. This rating measures the amount of water consumed by the washing machine per cycle. A lower WF number means the machine is more water-efficient.

These ratings are essential for appliance manufacturers to meet government standards for Energy Star certification. Additionally, knowing your washing machine's MEF and WF ratings can help you when applying for tax rebates. To find your washing machine's MEF and WF ratings, consult the user manual and look under the Product Specifications section.
