Indoor air quality

The carbon dioxide concentration and the indoor air quality in interiors are deemed to be the most important indicators that the quality of the indoor air is good enough, when people themselves are the main source of emissions. Poor indoor air quality leads to tiredness, lack of concentration and can even bring about illnesses. The CO2 concentrations should therefore not exceed 1,000 ppm as a rule.
