Specifically by providing the value for the CO2 concentration in the air (8) , conclusions can be drawn about aerosols with viruses (e.g.
Covid 19) present in the air. Although these are not directly detectable, increased CO2 pollution is at the same time a measure of virus-
contaminated air. This can be remedied by regular airing.
Permanently inhaling bad and stale air can cause tiredness, headaches, eye irritation, etc. The ability to perform and concentrate decreases
noticeably as a result.
