Ordinary tasks like showering, bathing, and shaving can put home-harming humidity into the air in your Southern California home. There’s good news, however—a straightforward bathroom ventilation fan can protect you from distorted wood, mold growth, broken drywall, and other problems connected with a humid bathroom.

Even if you have ventilation fans in your bathrooms, do you know if they’re the proper size? Are they as soft and energy-efficient as they could be? Econo Air is here to answer your questions.

Today’s bathroom ventilation fans are small and sleek and they run more quietly and efficiently than ever before. You’ll find a large range of choices, from classic fans that will get the job done to fans with fitted heat lamps, motion sensors, and heat-exchanger ventilation that helps block warmed air from leaking through your ventilation. While there are a lot of bells and whistles to select from, the most important characteristic of your fan is whether or not it’s full-sized enough to do its job.

Assessed by the cubic feet per minute (CFM) of air they transfer, a bathroom ventilation fan should be able to swap out the air in a bathroom at least eight times an hour. With a standard 8-foot ceiling, your ventilation fan should have a CFM rating about the number of square feet in your bathroom. So, if your bathroom is 5 feet by 8 feet, a CFM rating of 40 would be satisfactory.

If you have a taller ceiling, the equation gets a little more difficult. You’ll want to multiply the width of the room by its height and length, divide it by 60 and multiply by 8. Or, to keep it straightforward, you can use HGTV’s guidance for bathrooms larger than 100 square feet – establish your CFM requirements by toting 50 CFM for every toilet; 50 CFM for each shower, bath, and combo; and 100 CFM for each whirlpool.
