Why You Need a Bathroom Fan

Your bathroom is no stranger to moisture. From steamy showers to relaxing baths, and hot water to make shaving a smooth experience, it’s either the first or second moistest room in your home (let’s not forget the kitchen!).

Without proper ventilation, all that moisture can be an inviting breeding ground for mold, mildew, and other problems. Luckily, there are ways to keep bathroom humidity in check while avoiding structure damage and mold that’s hard to get rid of.  Here just a few ideas to get you started.

Choose the right bathroom fan. While having a window is helpful, a good vented fan will do a better job of pulling moisture-laden air out of the room. There are several to choose from, like fan-light combos, fans with a heat exchange function, and even motion sensor options that turn on and off when someone enters and exits the bathroom. Plus, most bathroom fans are whisper quiet.

Get a fan that’s properly sized. According to most contractors, a bathroom fan should provide eight air exchanges per hour. So, for example, if your bathroom is 100 square feet, look for a fan with 100 CFM capacity. If you have a jetted tub, get a fan with greater capacity to compensate for the added moisture.   

Professional installation. If you’re replacing an existing fan, you might be able to tackle that DIY project on your own. However, if you’re not comfortable working on electrical wiring, or installing a fan where there wasn’t one before, you’re better off leaving this project to a pro.

Install it in the right spot. Once you’ve chosen he right bathroom fan, make sure it’s installed in the right spot. Ideally, it should be close to the bathtub or shower but not close to a heating or A/C vent. For proper ventilation, have it vent outside.

Let the fan run. Allow the fan to run throughout your bath or shower and for abut ten minutes more after you’ve finished. If you turn it off right after your shower or bath, the space will not have enough time to fully air out. If you’re rushed in morning, consider installing a vent fan with a timer or humidity sensor so it can shut off automatically.

Clean the fan twice a year. A fan covered with dust and cobwebs works harder to improve ventilation. To clean it, simply shut off the electrical circuit to the bathroom, remove the fan’s cover, use the crevice tool on your vacuum to suck up cobwebs, dust, and grime, replace the cover, and turn the electricity back on.

Leave your shower curtain or door open. Whether you have a shower curtain or glass door, leave it open a bit to allow air to circulate.
