A brief YouTube video by Aaron Hartman, MD advising homeowners to measure indoor carbon dioxide (CO2) as a proxy for ventilation and occupancy. He states that CO2 levels above about 1,000 ppm indicate too many people or poor air circulation, and cites school measurements during the pandemic of roughly 2,000–3,000 ppm as examples of inadequate ventilation.

Questions this video answers

About 1,000 (ppm).

About 2,000–3,000 (ppm).

If you have elevated carbon dioxide levels over about a thousand, that actually means that you have too many people in the space or that the air is not being circulated properly. Some schools actually during the pandemic were found to have a level over 2 to 3,000 measurement of carbon dioxide, which means there are too many people in the space and or probably both. There was not being ventilated properly. So having ways to measure the amount of carbon dioxide in your house can be helpful.
