Ordinary tasks like showering, bathing and shaving can put home-harming humidity into the air in your Carpentersville home. There’s good news however—a straightforward bathroom ventilation fan can keep you from deformed wood, mold growth, damaged 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 right size? Are they as soft and energy efficient as they could be? Controlled Comfort HVAC Inc is here to answer your questions.
Today’s bathroom ventilation fans are small and modern and they work more quietly and effectively than ever before. You’ll find a hefty 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 prevent warmed air from getting out through your ventilation. While you can find a lot of bells and whistles to pick from, the most critical feature of your fan is whether or not it’s full-sized 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 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 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 satisfactory.
If you have a taller 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 easy, you can use HGTV’s advice 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.
