How to properly vent a bathroom fan for optimal air circulation and moisture removal?

To properly vent a bathroom fan for optimal air circulation and moisture removal, make sure 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 ensure efficient airflow. Install the duct with a slight slope towards the outside to help moisture drain out. Additionally, make sure the vent cap is installed correctly to prevent backdrafts and allow for proper airflow. Regularly clean and maintain the fan and duct to ensure it functions effectively.
