Adding a ceiling ventilation fan to your bathroom goes a long way in preventing the build-up of unhealthy mold and mildew on your walls, floors, and shower. A quality fan will help circulate the air and blow excess moisture created by steamy showers out the ductwork to vent it outside, helping to keep bathroom surfaces drier. Less moisture in the air helps inhibit the growth of mold and mildew which can cause respiratory issues, leave your walls, ceiling, and floor unsightly, and cause excessive wear on finishes.
A good ventilation system is a sound investment for your home. When selecting a bathroom fan, make sure you select a motor powerful enough for the size of the room. Some models include a heat lamp in their design to help speed up moisture evaporation and keep you warm when you step out of the shower, especially in colder seasons. Others also feature a ceiling light, letting you combine your fan with your bathroom's primary light source.
