Exhaust Fans Explained

A bathroom exhaust fan is an important fixture in any home to help in keeping moisture at bay. Many people loathe their bathroom fan because it is too noisy, but it doesn’t have to be. Many of the best bathroom fans are inaudible and do a great job in getting rid of odors and keeping moisture levels low to prevent structural damage from mold and mildew.

What to Look for in a Bathroom Fan

The fan that you select should be based on what size bathroom you have. Generally, the recommended size is to have airflow of one cubic foot per minute (CFM) for every square foot of bathroom area. For a bathroom larger than 100 square feet, it is often better to get two smaller fans than one bigger one. Most fans are labeled with their CFM rating and these numbers are quite reliable.

Another helpful thing to look for in an exhaust fan is that it is quiet. Industry noise ratings are measured in sones, with quiet fans typically being between .5 and 1.2 sones. 1.5 to 2 sones are considered to be a little louder, but still within a good range, while anything louder is considered too loud.

Most bathroom fans are easy to install. Look for an easily accessible electrical junction box that allows you to wire the fan without taking anything apart. Adjustable mounting brackets make positioning the fan easier and a ceiling light add-on is often a great feature for brightening up a dark room.

Exhaust fans are a necessary component to a home’s ventilation system. Check out the options and find one that fits your bathroom’s size and décor to ensure that your bathroom stays free of moisture and mildew.
