npub1lgdkj7vcxxvwxs29rv7sf8s3ve0gurpswjr77h5aztq5tvqmgcuq3le4sf (npub1lgd…e4sf) I have found that sometimes the CO2 inexplicably rises over 1000ppm (usually around 450-500) and then I will open the windows a bit.
I feel like my air just started doing this in the past year and I don't fully understand why. I would never have known without the monitor!
