Average tasks like showering, bathing and shaving can put home-destructive humidity into the air in your McMurray home. There’s good news still—a simple bathroom ventilation fan can save you from warped wood, mold growth, broken drywall and other issues 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 noiseless and energy efficient as they could be? Kowalski Heating, Cooling & Plumbing is here to answer your questions.
Today’s bathroom ventilation fans are small and sleek and they operate more quietly and economically than ever before. You’ll find a hefty range of selections, from average 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 getting out through your ventilation. While you can find a lot of bells and whistles to choose from, the most important feature of your fan is whether or not it’s large enough to do its job.
Rated 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 almost as high as the number of square feet in your bathroom. Thus, if your bathroom is 5 feet by 8 feet, a CFM rating of 40 would be adequate.
If you have a larger 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 heed HGTV’s tips for bathrooms larger than 100 square feet – determine your CFM requirements by toting 50 CFM for every toilet; 50 CFM for each shower, bath and combo; and 100 CFM for each whirlpool.
