As of 2015, some Menards bathroom fans are energy efficient. The Menard's website allows users to search specifically for fans that meet the Energy Star rating.
According to Energy Star, bathroom ventilation fans must meet several quality and performance specifications before they can earn the Energy Star rating. For example, small bathroom fans must produce less than 2.0 sones of noise, and they must emit at least 1.4 cubic feet of airflow per watt. If the fan includes a light, it must be a fluorescent or LED bulb. In addition, Energy-Star-rated ventilation fans must have warranties of at least one year.
