In the summer, I managed to have my apartment at 800ppm. But come fall we need to close the windows since it's too cold outside and 1200ppm is the new normal.
I open all the windows once a day to create a draft and it drops to 600-800ppm. But by then, I need to close them all again to reheat the apartment. This has the side effects of getting rid of all the humidity in the apartment and then the heating makes the situation even worst.
Most people I know go the entire winter without ever opening any windows. I wonder what their CO2 levels are.
