Bathroom FanA bathroom fan is a fan contained in a duct in the bathroom. It is used to circulate air in the bathroom. Bathroom fans can be designed to be turned on by a switch or set on a timing system. A bathroom fan is ideal as it dissipates leftover moisture from showers and odors quickly. Removing these odors will contribute to inside air quality and removing the moisture will decrease the level of humidity within the house. It is important to have a bathroom fan to decrease humidity because high humidity can result in mold growth and bacteria. The most common bathroom fans are impeller and blower fans. The disadvantages typically found with bathroom fans are that they are too noisy. Other complaints include that they move very little air, are not energy efficient, may cause back drafting and use high-wattage lighting. When choosing a bathroom fan, it is important to weigh all the advantages and disadvantages before making a purchase.
