Factors for a Good Indoor Atmosphere

In addition to the right temperature and humidity, the CO2 concentration in the indoor atmosphere is particularly important for our well-being indoors. In closed rooms with an insufficient supply of fresh air, the CO2 concentration quickly rises to a high level. Since CO2 is produced when we exhale, the more people there are in a room, the faster the CO2 content in the room air increases. Starting at a CO2 concentration of 0.1% by volume (1000 ppm), the tasteless and odourless gas has a negative effect on our well-being, performance and concentration. Often the ventilation system is only switched on when the indoor atmosphere is perceived to be stuffy or used up and this limit value has already clearly been exceeded. For comparison: fresh outside air has a CO2 content of about 400 ppm.
