Low CO2 no longer proxies safe, even though high ambient CO2 always proxies potential danger. That study you posted about airplane flights is an example of this. Even in the presence of filtration the virus is now efficiently transmitting at short, fast range. You can also look at the WHO’s calculator; it will show that ventilation or cleaned air do nothing to change the very high short range transmission rate. Tracy Thomas (npub1hmg…f0l6)
