Ordinary tasks like showering, bathing and shaving can put home-damaging humidity into the air in your Hudsonville home. There’s good news however—a modest bathroom ventilation fan can keep you from deformed 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 quiet and energy efficient as they could be? West Michigan Heating & Air Conditioning Services is here to answer your questions.
Today’s bathroom ventilation fans are small and smooth and they operate more quietly and economically than ever before. You’ll find a hefty range of choices, from simple 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 getting out through your ventilation. While there are a lot of bells and whistles to pick from, the most important characteristic 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 move, a bathroom ventilation fan should be able to replace 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. Thus, 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 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 follow HGTV’s tips for bathrooms larger than 100 square feet – establish your CFM requirements by increasing 50 CFM for every toilet; 50 CFM for each shower, bath and combo; and 100 CFM for each whirlpool.
