Re:The human brain evolved when CO2 levels were lower

I bought a CO2 monitor, and did the same experiment at my office, few weeks ago. I work in a very crowded room, with only one window.
At first the CO2 measurement was "out of range" (>=3000 ppm), but it was not a surprise because I already suspected something was wrong with the ventilation system. It has been fixed now, but CO2 levels hardly fall under 1500 ppm.
My advice is to open one or more windows whenever possible, at least one hour per day. If possible, one window should be opened the whole day. CO2 tends to accumulate in ambient air and it takes times to dissipate, far more than I imagined.

For contemporary home HVAC setups, air exchange systems are already an option. There are also air exchange systems that trigger based on CO2 concentrations. They’re demand-driven because concentrations can vary day to day depending on weather conditions, including wind.

EDIT: having read further down I see this article isn't about just the one paper - maybe my comments need peer review.
