Super fast reply from someone else - Yes, I have a standing air filter unit. If PPM went up I’d kick it into max gear.

(Now I have it running on very low continuously and it keeps PPM down)

The unit is rated for spaces 2x my square footage so on max it makes a quick improvement.

For CO2, minimize cooking / burning and kick on the air to attempt circulation. Worst case leave for a bit. (Used to be very sensitive to CO2 levels, it’s getting better).
