How to properly vent a bathroom fan to ensure effective air circulation and moisture removal?

To properly vent a bathroom fan for effective air circulation and moisture removal, ensure the fan is connected to a duct that leads outside the house, not just into the attic. Use a duct with a smooth interior to prevent clogs and make sure it is properly insulated to prevent condensation. The duct should be as short and straight as possible to maximize airflow. Additionally, make sure the vent cap is installed correctly to prevent backdrafts and water infiltration. Regularly clean and maintain the fan and duct to ensure optimal performance.
