Average tasks like showering, bathing and shaving can put home-harming humidity into the air in your Tucker home. There’s good news however—a simple bathroom ventilation fan can save you from warped wood, mold growth, cracked drywall and other trouble 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 noiseless and energy efficient as they could be? ACS Heating and Air Conditioning is here to answer your questions.
Today’s bathroom ventilation fans are small and modern and they operate more quietly and effectively 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 block warmed air from escaping through your ventilation. While you have a lot of bells and whistles to choose from, the most critical aspect 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 at least as high as 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 sufficient.
If you have a taller ceiling, the equation gets a little more complicated. 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 easy, you can follow HGTV’s tips for bathrooms larger than 100 square feet – determine your CFM requirements by adding 50 CFM for every toilet; 50 CFM for each shower, bath and combo; and 100 CFM for each whirlpool.
