Ordinary tasks like showering, bathing and shaving can put home-destructive humidity into the air in your Columbus home. There’s good news however—a straightforward bathroom ventilation fan can save you from deformed wood, mold growth, damaged 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 correct size? Are they as quiet and energy efficient as they could be? Wolfe & Sons Heating and Cooling is here to answer your questions.
Today’s bathroom ventilation fans are small and sleek and they work more quietly and efficiently than ever before. You’ll find a hefty range of options, from classic fans that will get the job done to fans with built-in heat lamps, motion sensors and heat-exchanger ventilation that helps avoid warmed air from leaking through your ventilation. While you have a lot of bells and whistles to select from, the most critical aspect of your fan is whether or not it’s full-sized enough to do its job.
Rated by the cubic feet per minute (CFM) of air they move, a bathroom ventilation fan should be able to swap out the air in a bathroom at least eight times an hour. With a normal 8-foot ceiling, your ventilation fan should have a CFM rating about 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 satisfactory.
If you have a larger ceiling, the equation gets a little more complex. 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 use HGTV’s guidance 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.
