This article though not scientific sums up what I am seeing empirically:
I finally broke down and bought a CO2 monitor (AirThings) and have been monitoring the CO2 in my house. Now with a house full of plants, I see absolutely no effect of the houseplants on indoor CO2. There could be a small effect that is too small to be noticeable but I need a gross overall effect to ensure lowered household CO2.
One interesting thing about getting the monitor though, is how high the CO2 gets in the house. I have fully aired the house and the outside air seems to be at 470ppm and then I didn't open the windows for 36 hours. The CO2 level quickly crept up to 1900ppm. Holy cow!
So it looks like it is back to the drawing board for me.
