Average tasks like showering, bathing and shaving can put home-harming humidity into the air in your Tuscaloosa home. There’s good news still—a simple bathroom ventilation fan can save you from warped wood, mold growth, cracked drywall and other problems associated 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 quiet and energy efficient as they could be? KDM Service Corporation is here to answer your questions.
Today’s bathroom ventilation fans are small and smooth and they work more quietly and economically than ever before. You’ll find a large range of options, from classic fans that will get the job done to fans with integrated heat lamps, motion sensors and heat-exchanger ventilation that helps avoid warmed air from leaking through your ventilation. While you have a lot of bells and whistles to pick from, the most critical feature of your fan is whether or not it’s big enough to do its job.
Graded by the cubic feet per minute (CFM) of air they transfer, a bathroom ventilation fan should be able to replace 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 adequate.
If you have a higher 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 simple, you can heed HGTV’s guidance for bathrooms larger than 100 square feet – verify your CFM requirements by increasing 50 CFM for every toilet; 50 CFM for each shower, bath and combo; and 100 CFM for each whirlpool.
