Normal outdoor air has around 400 ppm. For example, high humidity keeps the air moist and increases the likelihood of mold. The concept is that the higher your surrounding CO2 levels, the more significant the proportion of air exhaled from nearby people, and thus the greater the risk of SARS-CoV-2 particles in your immediate vicinity. That is why CO2 levels are an adequate proxy for Covid risk. This dissenting view yielded skepticism about mask usage and is one reason behind a lack of true mask mandates in the United States as many other countries implemented them. The best way to prevent the virus from spreading in a home or business would be to simply keep infected people away. As expected, closed environments with higher CO2 levels are much more likely to harbor transmission if an infected person is within the system.
