Healthy room climate

Modern buildings in particular are very well-insulated so that as little heat as possible is lost when heating. This also means that no air exchange with the outside air can take place. Fresh outside air has a range of positive properties, not just for the building, but also your health. Fresh and healthy air improves your concentration and contributes to better physical wellbeing in general.

Regular room ventilation also reduces the impurities and pollutants in the air. In a worst-case scenario, these can lead to diseases. Anyone who is not able to ventilate correctly, or forgets to do so, will have to deal with the formation of mould on the window and in the apartment.

This cannot just be damaging to your health, it also takes a great amount of time and effort to remove. And it is often associated with high financial costs. Correct housing ventilation can prevent this moisture and save costs. Besides this, room ventilation is a preventive measures to combat the development or onset of allergies.

If pollen, dust or cat hair remains in the room air for too long due to a lack of regular air exchange, the risk of an allergy attack for persons suffering from allergies is significantly higher.

Anyone wanting to ensure healthy room air without a ventilation system should be aware of a few things. The right strategy basically depends on the type of room it relates to.

A permanently tilted window must be avoided, as, in this case, the heat loss is too high. Pollutants or a high level of heat or humidity should be removed by direct ventilation. This is particularly the case when cooking or showering.

If you are drying the laundry in the apartment, a tilted window in the relevant room is recommended. Increased ventilation is also advisable if building moisture has been identified.

Otherwise the approach to ventilation depends on how the room is used. Ideally, bedrooms should be supplied with fresh air via a tilted window at night.

If the weather is too cold, especially in winter, a short but intense window ventilation, where the windows are opened wide, should take place in the morning. To prevent humidity, all rooms should also regularly be intensively ventilated for a short period.

This is particularly advisable in cases of poor air quality. Cellar rooms are a special case: as warm air hitting a generally cold cellar wall can lead to the formation of mould, cellar rooms should only be ventilated at night in summer. The time of ventilation is not important in winter.

In the bathroom and kitchen, ventilation is advisable after cooking or showering.
