I have several CO2 monitors including some from AirThings, Aranet4, and a industrial sensor in the form of a Vaisala GMP252 CO2 probe. They all track closely enough that I don't worry about it. The Vaisala is rated to +/- 40PPM which is accurate enough for living space environmentals.

Which one has a good price/accuracy ratio?
