How to keep CO2 levels low without outside air?

I live in a very polluted city, recently there were news of lead and other heavy metals in the air so just opening a window is not an option. I even confirmed the lead in the air by testing accumulated dust in my house with a swab lead test from Amazon.

I got some air purifieres and they keep pm10 and pm2.5 in line when the house is closed but in change the CO2 levels spike. If I open some windows the PM spike.

I'm seriously at a loss on what to do or what should be the priority.

Edit: Added some data from my monitor. Its a 3 month period of PM2.5 and PM10 Vs CO2, PMs practically overlap most of the time.
