alt Hacker NewsI have a CO2 detector at home and bought some for family members, but I have never had a portable one so they stay at home. Some of the high CO2 ppm numbers in the article make me want to double check them. My vague understanding form reading the manual of the one I bought and watching how the numbers can be thrown off by cleaning products used near them make me wonder how much these high numbers are from sources other than CO2. That said I would still suspect that the a good chunk of the relative differences would be from CO2 changes.

And, if CO2 works as a proxy measurement for virus transfer, maybe misdetected CO2 also works as proxy measurement for virus transfer.
You may have a sensor that estimates CO2 based on measured total volatile organic components. These are called eCO2 sensors, and were used instead of the gold standard NDIR sensors due to cost.
There are better cheap sensors available now, like the one in the $30 IKEA Alpstuga: https://cleanair.community/t/thoughts-on-the-ikea-alpstuga-a...
