8 Best Bathroom Fans to Stop Mold and Mildew

Staff, courtesy of Homewerks

A wet shower or bath can be relaxing, but the resulting humidity can lead to fogged up mirrors and harmful physical damage to the bathroom itself. This humidity facilitates the growth of mold and mildew, which can become dangerous for your family and take time to eliminate. Bathroom fans help get rid of that unwanted moist air by ventilating it out of your roof or soffit and can also keep your bathroom cool and clean.

What to consider

When choosing a bathroom fan, you must first ensure that it has the airflow capacity to effectively ventilate your bathroom. This is relatively easy to figure out by referring to the CFM (cubic feet per minute) metric of the fan you are considering. The CFM number will indicate how much air the fan will be able to move effectively, and by determining the square footage of your bathroom, you should be able to confidently choose a fan that will suit your space. For example, if you have a 100 square foot bathroom, make sure you have a fan of at least 100 CFM.

Another important factor to keep in mind is how easy or difficult it is to install the fan in your home. All of the options on this list will need to be hardwired to your home’s existing electrical supply, so if you’re planning on tackling the installation yourself, you’ll need to be very comfortable with electrical wiring. If not, you will need to hire an electrician or handyman to do the job for you. Remember that hiring a professional can potentially cost several hundred dollars, depending on the fan and your bathroom layout, so be sure to take that cost into account when calculating your bathroom budget. bathroom fan.
