Again: if you’re on an airplane, you should be wearing a high-filtration mask. It’s sound practice for the entire flight, but especially before takeoff and after landing.

Here are the CO2 measurements from a flight I took yesterday - the two peaks are from embarking and disembarking, showing the plane’s ventilation systems being shut off. This is unfortunately a frequent practice.
