Why is Airing so Important?

Modern houses today are perfectly sealed with thermal insulation, and energy losses are almost zero. Especially low-energy houses are equipped with a dense building envelope to avoid heat loss. Natural gas exchange can therefore no longer take place, yet access to fresh air is essential. Controlled ventilation of rooms is currently provided by devices adapted to this.


Ventilation is also a problem in apartments. Due to the subsequent thermal insulation measures, there is often no longer a sufficient inflow of outside air, for example via connections and leaks. There is a conflict of interest between reasonable thermal protection and the need for fresh air, which can be addressed with controlled domestic ventilation systems.

Breathe free!

Thanks to high-quality filters, the air in your room is always optimal. You can choose from different filter classes, right up to dust and fine dust filters (particle size PM 10 | PM 2.5). Not only allergy sufferers will breathe freely. How often the filter is replaced depends on how often it is used. If you use it extensively in the kitchen or on a busy street, it puts more pressure on the filter.
