A bathroom exhaust fan provides good ventilation, which prevents moisture and excess build-up of mold and mildew.
Bathroom ceiling fans are called intermittent ventilation and are used to capture and remove pollutants quickly at the source. The purpose is to exhaust excessive moisture or pollutants before they can spread to other parts of the house. Areas requiring this type of ventilation are bathrooms, kitchens, utility rooms, exercise rooms, workshops, garages and home offices.
Q. Where should I install the fan?
A. Typically the exhaust points should be located over or near the shower or tub and in an enclosed water closet.
Q. If mirrors stay steamed up or the grill is dripping water, is the fan(s) operating correctly?
A. You could try leaving the bathroom fan on longer to carry out more moisture, or check the design of the duct work. Poor design or damage may prevent the fan from moving the moisture out. You can insulate the ducts and check the roof jack which may be allowing rain to come into the duct, or it could be that condensation from warm, humid air in the house is striking the cold duct surface.
Q. What is a sone level
A. Sound levels are measured in sones. The higher the sone level, the noisier the fan. Buy as quiet a fan as you can afford. The way a fan is installed will affect its noise level. A low-sone fan attached to a duct that twists and turns, or is kinked or too small, will be just as noisy as the noisiest model.
