While HVI recommends that bathroom exhaust fans run for 20 minutes after each bathroom use, these fans are often not used as intended either because they are too noisy or, less frequently, because they use too much energy. As a result, homeowners suffer from poor air quality and potential health risks, and contractors receive complaints.
