A bathroom exhaust fan removes excess moisture from the air. If the fan is not removing enough moisture from the air, it should be replaced. One sign of a fan that is not working properly is a foggy bathroom after the shower has been used. Excess moisture in a bathroom can cause mold.

Bathroom exhaust fans have a cubic feet per minute, or CFM, measurement. The fans are recommended for certain bathroom sizes based on this measurement. A fan with between 50 and 60 CFM is typically recommended for powder rooms. One with between 70 and 90 CFM is recommended for medium bathrooms, and one with 100 CFM or more is recommended for master bathrooms. Bathroom exhaust fans also have a sones measurement, which indicates how loud the fan is. A higher number indicates a louder fan, with a rating of two being relatively quiet.

When installing a new bathroom exhaust fan, unscrew and remove the old fan first. Installation instructions vary based on the fan model. Certain fans may be easier to install if you have access to the attic.
