I joined the CO2/pm2.5 club, with a HOTKREM Indoor 5-in-1 Air Quality Monitor.

So far I'm surprised that CO2 has been "low" even with the house closed up, less than 700ppm.

Also that with the house open this morning pm2.5 is higher 17 ug/m3 vs 6 or 7 closed.

All with a grain of salt of course, given a $60 device.
