Exhaust fans are designed to vent moisture, odors, and stale air from a room outside. They are typically used in bathrooms, kitchens, and attics to prevent issues like mold, mildew, and excess humidity.
Exhaust fans help reduce moisture in the air, which is especially important in bathrooms and kitchens where high humidity can damage walls, paint, and wallpaper. Proper ventilation is also crucial for maintaining indoor air quality and comfort.
