VALLEJO — Many homeowners think of bathroom exhaust fans as a “one size fits all” affair, but in reality, there are several variables to consider. As modern homes are being built tighter to maximize energy efficiency, the need for adequate ventilation has increased, which is why building code legislation now requires bathroom fans to be installed in any new or remodeled bathrooms, regardless of whether they have windows.
Few people realize that a bathroom fan doesn’t merely reduce moisture—it actually improves air quality by removing pollutants like mold, mildew and dust from the indoor environment. However, simply having a fan isn’t enough; you need one that’s correctly sized for the space. In determining the right fan size for your bathroom, remember that proper airflow is a minimum of 1 cubic foot per minute for each square foot of bathroom.
In addition to correctly sizing your fan, you’ll need to decide what features you want. In addition to the fan itself, you can get a model that has an LED or fluorescent light. Other optional features include motion sensors, variable speeds, heat, condensation sensors, night lights and delay timers.
After selecting your bathroom exhaust fan, you’ll need to have it installed. Since different bathroom fan models have different wiring requirements, it’s best to consult a licensed electrician to ensure your new fan will work properly following installation.
