735ppm in the house right now with the windows open all night, no wind.
No fires near I assume. Could just be from cars in your area (??) Water heater or other pilot lights?

I am not sure exactly what the health cut off line is so to speak, seems a bit high but not not sure if dangerous.

What meter are you using?

Outside it's around 510ppm. This is quite normal for inside the house.. Even higher in the winter.

Plants give off CO2 at night. Here I am surrounded by corn and trees. The CO2 will cycle from as high as 700ppm to 350ppm daily with the high around 8am and the low around 4pm.

Yes that does sound OK. I want to see what our readings are winter and spring especially when this place goes jungle mode. Right now, bone DRY.
 
El Paso right now.

I've got some data logs of outside CO2. You can see the rise and fall. These are probably cherry picked from 24/7 data. Wind and rain make a big difference. So these should be calm days.

And the meter I used is self calibrating. You have to put it outside once a month for it to acclimate and set itself to 400ppm regardless of the actual reading. Took me years to figure this out (finally read the directions). If you leave it inside where it's constantly high it will slowly read lower and lower that the actual value over the years.
