I recently bought one expecting to see something interesting and it mostly just stays stable all day, even with the door closed. Maybe my house has good ventilation.

In my case I have exceptionally drafty windows. The rooms with new windows all have CO2 elevate almost linearly with time human is in room.

Stays stable at 400ppm or 1500ppm?
