Upgrade Your Bathroom Fan to Reduce Mold and Sound

A properly functioning bathroom exhaust fan will draw out moisture, odors and other pollutants, thereby improving indoor air quality. Upgrade your fan to keep your bathroom clean and mildew-free.

Bathroom fans were thought of later, but they are vital for limiting humidity. Excessive moisture and water vapor can lead to mold, mildew, and paint and wallpaper cracking and peeling. If you suspect that the exhaust fan is ineffective, you can replace it yourself.

Before taking on this job, you need to buy a new fan large enough to ventilate your bathroom. Use this calculator or formula (Bathroom Length x Width x Height x 0.13 = Minimum CFM) to determine your ideal CFM (Cubic Feet Per Minute) for your bathroom fan. Always round off when buying a fan. Then look at the sound rating, which determines how much sound it makes, and choose a fan with a sound rating of 1.5 or less (lower number = quieter).

A quality fan with a low sound rating can be found for $ 100-150 . Some are even available with built-in light.

To install a fan, you need to turn off the circuit breakers to turn on the electricity and have easy access to the workspace to finish the ductwork. If your new fan is larger than the one you are replacing, you will also need to trim the drywall to create a larger opening. The video above details how to complete this DIY project.
