Open the windows wide, provide 5 to 10 minutes for complete air exchange.
The exchange of used air for fresh air works very quickly in cold outdoor temperatures.
Below +5 °C, a maximum of 5 minutes is sufficient.
Airing even in rain
Heated in the apartment, cold humid air quickly results in dry room air.
Moisture through sleeping, showering, cooking
The moisture that arises when sleeping, showering and cooking should be dissipated directly into the open air through an open window or open patio door. Untilted windows, use doors for this purpose, as the replacement is small.
Please also make sure that the moisture is not directed to other open rooms. Otherwise, condensate can develop on cold corners, so the best conditions for mould!
Laundry drying in the apartment
A wash dry in the apartment can be a reason for moisture in the rooms. Please place in the apartment only at the correct room temperature and humidity. To regulate the humidity, close the door of the room and perform shock ventilation several times during the drying period. This means that there is no damage caused by mould in the long term.
Cellar ventilation in summer
Basement rooms only ventilate when it is colder outside than in the basement. Already in early summer, the warm air from outside is harmful, because its moisture load condenses on the cold components and furnishing objects. It’s best to air at night.
