I monitor my office. It works its way up to 1300-1400 ppm during the day. At the start of the day it is the outdoor baseline.

- lucb1e 7y agoWait, GP said 800-1000, you have it at 1300-1400... isn't 1000 like the headache line? Shouldn't it be around 400-600 in a healthy environment? Edit: Looking it up, the Wikipedia article on CO2 has the following to say on the topic: > A study of humans exposed in 2.5 hour sessions demonstrated significant negative effects on cognitive abilities at concentrations as low as 0.1% (1000ppm) CO2 > Another study observed a decline in basic activity level and information usage at 1000 ppm, when compared to 500 ppm. So 1ppk is definitely bad. Another datapoint is from 5ppk: > At [5000 ppm for an 8h period, the] International Space Station crew experienced headaches, lethargy, mental slowness, emotional irritation, and sleep disruption.
- steve19 7y agoThanks for the concern. Yes it is bad, which is why I built a CO2 meter. I need to get alerts to ensure either I get more air to me, or I leave the office.
