I used an Awair Element after wondering if Co2 buildup was causing my groggieness in the morning and an ever so slight dull headache.
My bedroom was quite small at the time, but I measured the same effect of buildup in a larger bedroom, just the Co2 level took a little longer to reach it's peak.
In the small room it took about 45 mins to climb to about 1400 after I closed the door and went to sleep.
I'm currently trying to install some above-door vents to improve circulation but this is a topic most people don't consider at all, even though studies have shown the effects of classrooms having high Co2 concentrations on exam results and cognition.
> I wouldn’t put too much effort into vents above a door as we’ve seen that CO2 will leak through doors and even floors/ceilings very quickly.
I'd like it to vent out into the hallway and the rest of the apartment though, so not sure what you mean by it leaking through doors? It's obviously not leaking enough, hence the addition of a vent. It's either that or keeping my door open all night which isn't feasible due to noise by other family members waking up etc.
I've been using Netatmo stations in each room plus one outside for a decade. They monitor temp, CO2, and humidity. My CO2 levels were nightmarish during wildfires in my part of California across multiple years. Of course, the air tasted horrible and it was absolutely evident how bad it was just breathing two different years so it was not at all surprising to see that correlated on instruments that I check multiple times every day.
I'm using a desktop CO2 meter, they're cheap and accurate, and can be tested by just putting them outdoors and confirming that they read known outdoor levels correctly. What you are saying is not unlike doubting that it's possible to measure temperature with a thermometer- CO2 measurement is extremely reliable, cheap, and mature technology.
This is the meter I am using, costs $39, and is a calibrated instrument with +/- 3% accuracy. I have an academic colleague that uses these same devices for scientific research on plant metabolism, and they are highly accurate and are optionally self calibrating just by opening a window or putting them outdoors.

We monitor air data quite closely at work.
CO2 rises really fast with people in even a large space.

When was it calibrated?
