You get used to it after a while. I've been living in an area with extreme levels of outside air pollution (think Mumbai or Beijing, but much worse) for many years, so my windows are almost always closed shut. I have a CO2 meter and it reports an average of about 2000 ppm. I feel fine, and don't feel any difference to the normal level of 440 ppm. I'm pretty certain it would show on objective cognitive tests, but personally I really don't feel any difference.

This sounds seriously unhealthy. Consider finding different place to live if at all possible. Air pollution is a killer.

If I was in that situation I would consider opening the windows twice a day for 15 minutes, then running a good (and properly sized) air purifier on full blast for an hour.

  Depending on the size of your house/apartment, you'll use up that oxygen in a couple of hours and will be back at 1000+ levels. Plus, there must be some ventilation in OP's setup already, as the CO2 levels are at 2000, and without ventilation they'd just rise until he passes out...

  The sibling comment is right, it doesn't help very much. The CO₂ level goes above 800 ppm (which is already considered unhealthy) in ~20 minutes, rises to ~2200-2400 ppm (depends on wind speed and atmospheric pressure) in the course of a couple of hours, and then just stays there for days on end. I put all my pollution data into Grafana and it makes making decision when to open (or close) a window that much easier. (Yeah, you have to make a thought-out decision to not feel terrible. It's a whole ceremony.)

The biggest threat in your case is the PM2.5 In Beijing, the difference before and after the air purifier was enormous in my own experience.

what hardware/software/data are you, or anyone else, using to get these readings?
