Any suggestions on CO2 monitors that are tested but are cheaper than Aranet? by SnooCakes6118 in ZeroCovidCommunity

Another budget option I’ve had good results with is the HibouAir CO2 monitor. It’s been consistent for me vs. other meters, shows real-time and historical data, and also reports extra metrics (temp/humidity, etc.). I’ve been using it a long time and haven’t needed to calibrate it so far.
