Ordinary tasks like showering, bathing and shaving can put home-destructive humidity into the air in your Columbia home. There’s good news still—a simple bathroom ventilation fan can keep 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 proper size? Are they as quiet and energy efficient as they could be? Watts Electric & A/C Inc is here to answer your questions.
Today’s bathroom ventilation fans are small and smooth and they operate more quietly and efficiently than ever before. You’ll find a hefty range of choices, from classic fans that will get the job done to fans with fitted heat lamps, motion sensors and heat-exchanger ventilation that helps prevent warmed air from getting out through your ventilation. While there are a lot of bells and whistles to pick from, the most imperative feature of your fan is whether or not it’s big enough to do its job.
Assessed by the cubic feet per minute (CFM) of air they push, a bathroom ventilation fan should be able to replace 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. So, if your bathroom is 5 feet by 8 feet, a CFM rating of 40 would be satisfactory.
If you have a higher 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 use HGTV’s tips 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.
