Mildew, and Mold, and Moisture! Oh, My!
Ventilation fans, also known as exhaust fans, help circulate the air inside a home. This helps keep a house cooler in the summer and warmer in the winter. Fans accomplish this by circulating warm/cool air. Ventilation fans also help prevent the growth of mildew and mold in places such as attics or bathrooms. Circulating air disperses the moisture in small enclosed spaces. Varies types of ventilation fans are available, including roof ventilation, exterior-mounted, combination ventilation and in-line ventilation fans.
