Average tasks like showering, bathing and shaving can put home-destructive humidity into the air in your Long Beach home. There’s good news however—a straightforward bathroom ventilation fan can save you from deformed wood, mold growth, damaged drywall and other problems 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 soft and energy efficient as they could be? YES R&M Inc. is here to answer your questions.
Today’s bathroom ventilation fans are small and modern and they run more quietly and effectively than ever before. You’ll find a hefty range of selections, from average fans that will get the job done to fans with built-in heat lamps, motion sensors and heat-exchanger ventilation that helps block warmed air from getting out through your ventilation. While there are a lot of bells and whistles to choose from, the most important characteristic 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 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 about 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 adequate.
If you have a larger ceiling, the equation gets a little more complicated. 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 heed HGTV’s tips for bathrooms larger than 100 square feet – establish your CFM requirements by adding 50 CFM for every toilet; 50 CFM for each shower, bath and combo; and 100 CFM for each whirlpool.
