Choosing a Bathroom Fan
Bathroom exhaust/ventilation fans are key to preventing humidity and moisture buildup, which can damage paint, lead to the growth of mold and mildew, and harm drywall and wood supports. Use these tips to choose a fan that is sized and vented appropriately for your bathroom.
According to recommendations from the Home Ventilating Institute, a bathroom ventilation system should change the air eight times an hour, or one cubic foot per minute (CFM) per square foot of bathroom, with a minimum of 50 CFM. For example, a bathroom measuring 8 feet by 10 feet would indicate a fan rated for at least 80 CFM. If your bathroom measures larger than 100 square feet, you should also add 50 CFM for each toilet, shower, and bathtub (100 CFM for a whirlpool tub).
Energy Star-rated bathroom fans use 20% less energy than minimum federal guidelines. Many fans come with electricity-saving options, such as an on/off timer, humidity sensors, or motion sensors.
Once you've determined the type of fan that is right for your bathroom, you can look for additional features to increase your comfort level. Bathroom fans can come with lights, heaters, and even nightlights. And they don't have to look boring, either. Just as your other bathroom accessories do, bathroom fans come in a wide variety of styles. Whether your taste is contemporary, traditional, or industrial, be sure to select the fan that looks best in your bathroom.
