Average tasks like showering, bathing and shaving can put home-destructive humidity into the air in your Dayton home. There’s good news however—a straightforward bathroom ventilation fan can keep you from warped wood, mold growth, damaged drywall and other trouble 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 quiet and energy efficient as they could be? Jent Mechanical LLC is here to answer your questions.
Today’s bathroom ventilation fans are small and smooth and they work more quietly and effectively than ever before. You’ll find a large range of options, from classic 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 escaping through your ventilation. While you can find a lot of bells and whistles to pick from, the most imperative aspect of your fan is whether or not it’s big enough to do its job.
Rated by the cubic feet per minute (CFM) of air they move, 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 about 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 adequate.
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 follow HGTV’s advice for bathrooms larger than 100 square feet – determine your CFM requirements by adding 50 CFM for every toilet; 50 CFM for each shower, bath and combo; and 100 CFM for each whirlpool.
