Ordinary tasks like showering, bathing and shaving can put home-destructive humidity into the air in your Long Island home. There’s good news however—a modest bathroom ventilation fan can keep you from deformed wood, mold growth, cracked 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? Airmax Long Island Inc is here to answer your questions.
Today’s bathroom ventilation fans are small and sleek and they work more quietly and efficiently than ever before. You’ll find a hefty range of choices, from average 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 getting out through your ventilation. While there are a lot of bells and whistles to select from, the most critical feature 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 transfer, a bathroom ventilation fan should be able to swap out 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 simple, you can use 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.
