Original Note:
CO2 sensors are not a proxy for air cleanliness when HEPA filters are used, as in aircraft. Filters clean air, but do not change the composition of a gas https://molekule.com/blogs/all/do-air-purifiers-remove-carbon-dioxide Additionally, the Aranet CO2 sensor shown is calibrated for sea level, not aircraft use https://forum.aranet.com/all-about-aranet4/altitude-compensation-1/
