Ordinary tasks like showering, bathing and shaving can put home-destructive humidity into the air in your York home. There’s good news however—a simple bathroom ventilation fan can save you from deformed wood, mold growth, damaged drywall and other issues related 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 noiseless and energy efficient as they could be? Strine's Heating & Air Conditioning is here to answer your questions.
Today’s bathroom ventilation fans are small and modern and they operate more quietly and effectively than ever before. You’ll find a large range of selections, from simple fans that will get the job done to fans with built-in heat lamps, motion sensors and heat-exchanger ventilation that helps prevent warmed air from leaking through your ventilation. While you have a lot of bells and whistles to pick from, the most imperative feature 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 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. So, if your bathroom is 5 feet by 8 feet, a CFM rating of 40 would be adequate.
If you have a higher 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 simple, you can use HGTV’s advice for bathrooms larger than 100 square feet – verify your CFM requirements by increasing 50 CFM for every toilet; 50 CFM for each shower, bath and combo; and 100 CFM for each whirlpool.
