Average tasks like showering, bathing and shaving can put home-harming humidity into the air in your Moline home. There’s good news still—a simple bathroom ventilation fan can save you from deformed wood, mold growth, damaged 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 quiet and energy efficient as they could be? J.L. Brady Company LLC 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 hefty range of choices, from average 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 getting out through your ventilation. While there are a lot of bells and whistles to choose from, the most critical characteristic of your fan is whether or not it’s large enough to do its job.
Assessed by the cubic feet per minute (CFM) of air they move, a bathroom ventilation fan should be able to exchange the air in a bathroom at least eight times an hour. With a typical 8-foot ceiling, your ventilation fan should have a CFM rating almost 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 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 tips 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.
