How to properly vent a bathroom exhaust fan?

To properly vent a bathroom exhaust fan, you should ensure that the fan is connected to a duct that leads outside the house. This duct should be as short and straight as possible to allow for efficient air flow. It is important to make sure the duct is properly insulated to prevent condensation and mold growth. Additionally, the vent cap on the exterior of the house should be installed correctly to prevent backdrafts and pests from entering. Regular maintenance and cleaning of the fan and duct are also important to ensure proper ventilation.
