An N99 mask will not magically change the amount of CO2 you’re exposed to… that’s an issue about air turnover inside the cabin.

Lost in translation a bit.

Your post says "Airplanes are safe because they have air filters." which for me reads as planes when flying. That's why I added the bits about the differences between boarding and flying.

I absolutely respect you and your work, so please don't take this the wrong way.

That was my point! Air is terrible while on the ground.

Your reply was like someone saying it's dark at night, and you reply "to be fair, it is night."

I don't know what the ventilation rate is, but... I'd expect it to stay somewhat elevated.

To be fair, you're saying that's during boarding and that is exactly when air conditions are bad.

From what I've read, modern aircraft have air filtration systems that either match or exceed those in operating theatres. So, yes, boarding and off loading when the engines are off - bad. Actually flying - not so bad.

Or have I got it all wrong?

I guess the APU and the air conditioning weren't running. They were a requirement during the hot phase of Corona. Nowadays most airlines prefer to save fuel (cost), so unless it is very hot or cold you probably won't get fresh air on the ground.

Latest after takeoff and during the whole flight, levels should go way down as you might have measured.

Is it better once you sit?
