CO2 monitors in schools. A useful tool in ventilation, providing they are used intelligently and acted on.
The next challenge is seeing how well they are used and monitored in wide scale use - and as the weather becomes colder and colder.
And how schools will adapt re uniform

Interesting graph here where a teacher was asked to use the CO2 monitor one week and not the other week.
When not used CO2 grows throughout the morning to exceed a 1600 peak but gradually drops off to lunch time. Rises in afternoon to 1200 peak.
Using monitor 400-600 all day

I don’t know how this works in schools with non opening windows - esp with recirculating air conditioning.
This was the guidelines for CO2 monitoring Albert levels. Lower than many manufacturer’s factory settings.

*alert*.
Now to test on a far larger scale whether Covid in classrooms keeping CO2 levels low also have significantly lower levels of school transmitted Covid.
CONCLUSION thus far.:-
