Dear god @[email protected] please ventilate your planes while boarding, this is an obscene level of CO2 and therefore everyone on this plane is breathing in everyone's else's air and sharing RSV, flu and #COVID19, the worst kind of xmas present!!

@irenetosetti this CO2 level is really bad.
But in planes there are HEPA filters that are intended to filter out viruses and are not able to filter out CO2.
In the presence of HEPA filters we have no clue which CO2 level corresponds to which potential virus density.
That said Iā€™d wear a good mask in a plane at any CO2 level.

"please ventilate your planes while boarding" no ventilation => filters not in use, that is the problem

@fishelfe @irenetosetti technically, planes get electricity from ground and could ventilate.
How do we know if they are (not)?
Be aware that ventilation is different from running air nozzles, which should not be used as they disturb the laminar ventilation flow.

@gerdcastan @irenetosetti
Looking at THAT CO2 reading - what kind of special, CO2 enriched air would they be ventilating with?

Filters. do. not. Filter. out. CO2.
Never.

EXACTLY! That why it needs fresh air ventilation!
