Everyday tasks like showering, bathing and shaving can put home-damaging humidity into the air in your Neptune City home. There’s good news however—a straightforward bathroom ventilation fan can protect you from deformed wood, mold growth, cracked drywall and other trouble connected 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? Aggressive Mechanical is here to answer your questions.
Today’s bathroom ventilation fans are small and smooth and they work more quietly and economically than ever before. You’ll find a large range of options, 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 getting out through your ventilation. While there are a lot of bells and whistles to pick from, the most important feature 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 move, a bathroom ventilation fan should be able to exchange 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. Thus, 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 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 easy, you can heed 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.
