Since getting this CO2 meter, I’ve found there’s a high correlation with being unfocused and/or irritable with 800+ readings. Reminder to get some fresh air, open the window, etc.

Looks like the Aranet is 3x-5x more expensive than other CO2 monitors I see on Amazon that have decent reviews. Is it just the app that makes this one worth the extra investment?
