Bathroom Fan Running but Still Wet? The Fan May Not Be the Problem

Your bathroom fan is running, but the mirror, ceiling, or walls stay wet. The important question is not whether the motor makes noise. It is whether moist air can travel through the complete air path and discharge outdoors. This Everyday Reality Check episode shows a safe, evidence-first way to check the system from the room to the exterior. You will learn what a tissue-at-the-grille check can and cannot prove, why replacement air matters, how the duct and exterior termination affect installed airflow, and when the evidence belongs with a qualified professional. The video also explains why a fan label is only a starting point. A rated fan can deliver less airflow after installation when the grille, damper, duct route, duct size, or exterior termination adds restriction. Cold-duct condensation is discussed as a possibility to inspect, not a diagnosis from one damp mark. Important safety note: do not open energized equipment, enter an unsafe attic, climb onto a roof, or disturb a large concealed growth area. Use safe observations and the manufacturer's instructions. Electrical, roof, concealed duct, and larger moisture problems may require the appropriate qualified professional.
