Ordinary tasks like showering, bathing and shaving can put home-harming humidity into the air in your Wausau home. There’s good news though—a straightforward bathroom ventilation fan can protect you from deformed wood, mold growth, broken 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 proper size? Are they as quiet and energy efficient as they could be? Gilray Heating and Cooling is here to answer your questions.
Today’s bathroom ventilation fans are small and modern and they work more quietly and efficiently than ever before. You’ll find a hefty range of choices, from simple fans that will get the job done to fans with fitted heat lamps, motion sensors and heat-exchanger ventilation that helps avoid warmed air from leaking through your ventilation. While you can find a lot of bells and whistles to choose from, the most imperative characteristic of your fan is whether or not it’s big enough to do its job.
Graded by the cubic feet per minute (CFM) of air they push, 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 almost 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 adequate.
If you have a higher 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 straightforward, you can use 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.
