I saw that. Did you see the part where passenger comfort and decreased disease transmission in the enclosed space of a fully loaded 737 REQUIRES less than 1000ppm of CO2? Evidently not.
OSHA recommendations for building air quality are not adequate for enclosed airplanes, and the article plainly states that. You don't want to accept the truth, and refuse to believe that only your own information is valid. Try reading the entire article, and the conclusions CAREFULLY.
Until you do, post to somebody else. Maybe they'll fall for your viewpoints. I no long have any interest in them.
Show me where it is above 1000 ppm. Thank you.
