How often should I run my bathroom fan? Should I get a timer?

To prevent moisture problems in your bathroom, you should turn on the bathroom fan when showering or taking a bath. The fan should be left running at least 30-54 minutes (or longer) afterwards to get rid of any excess moisture. Getting a timer for your bathroom fan can help ensure that your bathroom stays well-ventilated. You can set the timer to leave your bathroom fan running for a custom or manufacturer-set period of time and have it automatically shut off when the time is up.
