No chance for humidity and mould
Dry heating air can quickly cause a cold. However, there is a risk of mould and spore growth if the air is too humid. From a medical-domestic point of view, the relative humidity of the room air should be at least 30% and no more than 70%; 40% to 50% is ideal. At above 70% relative humidity, there is a particular risk of mould formation! This humdidity must be removed from the house by all means, since otherwise it will condense and, for example, settle as water on the wall or windows. Mould initially forms at these points, and then spores. This damage is accompanied by an increased risk of respiratory illnesses, asthma, allergies in general and mites and mould allergies.
How can you prevent such a development? By ensuring the controlled removal of humid and used up air - at all times, even when you are not at home. Convenience ventilation systems constantly provide sufficient air circulation and discharge the humid air from the house. The best protection for your family and home.
