Average tasks like showering, bathing and shaving can put home-destructive humidity into the air in your Heflin home. There’s good news though—a straightforward bathroom ventilation fan can protect you from deformed wood, mold growth, broken drywall and other issues connected 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? Bain Heating & Air Conditioning, Inc is here to answer your questions.
Today’s bathroom ventilation fans are small and sleek and they run more quietly and effectively than ever before. You’ll find a large range of choices, from average 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 getting out through your ventilation. While you have a lot of bells and whistles to pick from, the most critical aspect of your fan is whether or not it’s large 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 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 sufficient.
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 simple, you can follow HGTV’s tips for bathrooms larger than 100 square feet – determine your CFM requirements by increasing 50 CFM for every toilet; 50 CFM for each shower, bath and combo; and 100 CFM for each whirlpool.
