The bathroom is a room in our houses in which efficient ventilation is extremely important, not only for our comfort but above all for health. Steam generated after each bathing should be regularly removed and replaced with fresh air coming from outside. Excess of this moisture is able to do us more harm than we think.
This is a myth
Most people think that the bathroom ventilator performs primarily the function of removing various odors from the bathroom. A more important function is, in fact, the evacuation of warm, humid air, which was created even when bathing or showering. If your bathroom does not yet have a ventilator, it would be good to install one to ensure optimal conditions in this room.
