Bathroom Fans reprinted courtesy of ServiceMagic

Bathroom exhaust fans are desirable in any bathroom, and they are required in bathrooms that have no windows or a window that can't be opened. On the topic of bathroom ventilation, click this link if you would like to read more about bathroom windows.

Bathroom fans should exchange the air in a bathroom completely every five minutes. In addition to keeping the air fresh, they also help inhibit the growth of mildew and other fungi that easily breed in a bathroom.

Fans can be noisy, so listen to the model you are buying before you bring it home.

Before installing your bathroom fan or beginning any electrical work, be sure you have the required permits. Failure to do so is illegal and may invalidate your homeowner's insurance. If you are not comfortable or capable installing your own bathroom fan, click here to get matched to a Handyman.

Many changes will be dictated by electrical code, for example, the number of outlets per circuit or use of special GFCI outlets in bathrooms or kitchens. Your service professional should be familiar with these codes.
