Ordinary tasks like showering, bathing and shaving can put home-harming humidity into the air in your Cedar Rapids home. There’s good news though—a simple bathroom ventilation fan can save you from distorted wood, mold growth, cracked drywall and other trouble connected with a humid bathroom.
Even if you have ventilation fans in your bathrooms, do you know if they’re the correct size? Are they as noiseless and energy efficient as they could be? Ilten's Incorporated is here to answer your questions.
Today’s bathroom ventilation fans are small and sleek and they run more quietly and effectively than ever before. You’ll find a large range of choices, from classic fans that will get the job done to fans with built-in 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 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 exchange 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. Therefore, if your bathroom is 5 feet by 8 feet, a CFM rating of 40 would be sufficient.
If you have a larger 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 follow HGTV’s tips for bathrooms larger than 100 square feet – verify your CFM requirements by adding 50 CFM for every toilet; 50 CFM for each shower, bath and combo; and 100 CFM for each whirlpool.
