How to Shop Standard Bath Exhaust Fans
A good quality standard bath exhaust fan eliminates moisture from the wettest area of the house, protecting homeowners from mold, mildew and fungi, all while cleaning the air from stale odors and preventing walls and fixtures from cracking and waving. It is highly recommended to follow several tips in order to choose the right standard exhaust fan for the bathroom area.

In order to find out the required number of CFM, it is needed to measure the overall square footage of the room. According to the Home Ventilating Institute, one square foot of bathroom area should correspond to one CFM. The minimum airflow rate is 50 CFM. If the bathroom space is larger than 100 square feet, additional 50 CFM are needed for each bathtub, toilet, shower, and jetted tub.
The noise level value is measures in Sones. One Sone noise can be compared to the sound of a running refrigerator. Three sones value is a bit louder than a usual office noise level. A standard bathroom exhaust fan can have a noise level starting from below 1 and up to 4 Sones. In order to choose the right model, think over which noise level you can bear for about 15 minutes – this is an approximate time needed by the fan for air cleaning.
Contemporary bath exhaust fans can be fitted out with a wide choice of added features. There are options for lighting, automated timers, and heaters. There also exists a bath fan equipped with a humidistat, which automatically regulates the fan’s workflow in accordance with the humidity level inside the bathroom.
