To rule out the latter, I would like to test the indoor air quality for a couple of days.  Has anyone got perhaps an unused CO2 sensor lingering about, or Chinese rip-off of the SCD-40 sensor, that I could use for a couple of days?

I have one of these https://github.com/davidkreidler/OpenCO2_Sensor

You're welcome to borrow that for a bit to see what kind of CO2 levels you're getting. I'll take it to space this evening.
