Why bathroom fans are about moisture
The fan sends shower vapor outdoors before that water wets the room and the house.
When the purchase is complete, return to the original window. It will refresh.
From the opening
A bathroom fan is there to remove water vapor that a shower or a bath dumps into a small room. Odor control is real and secondary, because the lasting damage from a wet bathroom is moisture left on surfaces and in air that then wanders into the rest of the house. The opening covers shower vapor as the real load, why the duct must go outdoors, and fog clearing is the visible sign.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
