Everyday tasks like showering, bathing and shaving can put home-damaging humidity into the air in your Winnipeg home. There’s good news though—a modest bathroom ventilation fan can keep you from distorted 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 proper size? Are they as noiseless and energy efficient as they could be? Kirkfield Heating & Air Conditioning is here to answer your questions.
Today’s bathroom ventilation fans are small and smooth and they run more quietly and efficiently than ever before. You’ll find a large range of options, from average fans that will get the job done to fans with integrated heat lamps, motion sensors and heat-exchanger ventilation that helps avoid warmed air from leaking through your ventilation. While there are a lot of bells and whistles to select from, the most imperative 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 push, a bathroom ventilation fan should be able to exchange the air in a bathroom at least eight times an hour. With a typical 8-foot ceiling, your ventilation fan should have a CFM rating at least as high as the number of square feet in your bathroom. Therefore, 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 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 straightforward, you can follow 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.
