Most of the US is currently blanketed with wildfire smoke. Are you sure CO2 is the problem? Are you testing for PM2.5, PM10, VOCs, humidity, etc?

Yeah, I have an AQI meter too, and my CO2 meter also tracks humidity. I'm pretty sure it's the CO2. It's admittedly a minor annoyance, I'm just trying to make the perfect work setup.
