One possible solution is to open the windows, but this can generate a significant heat loss depending on the seasons and additional energy consumption. The solution proposed here is to install a bathroom fan with light.
The bathroom fan with a light specifically designed for bathrooms and toilets help manage this problem. These fans are typically 15 x 15 cm and can be installed in the wall or ceiling. They usually have a circular opening at the back to which a rigid or flexible duct can be attached. When the air duct leads to an outside wall, its end ends in a plate with small fins (like louvers). The air that escapes (pushed by the fan) pushes the fins that remain open. When the fan does not work, the fins fall back and prevent the entry of rain or wind. With a duct leading to the roof, a special ventilation tile is used.
The simplest solution is to connect the bathroom fan with light and timer. The fan turns on when the light is on and stops when the light is off. The main flaw of this solution is that odors or moisture may not be completely removed when the occupant leaves the room. Other solutions are available if the house is equipped with a home automation system. or not when the light is on.
