Garden Myths - Learn the truth about gardening
Do Houseplants Increase Oxygen Levels?
https://www.gardenmyths.com/houseplants-increase-oxygen-levels/
"In most homes the plants cannot produce oxygen at anywhere near the amounts we consume."
(Calculations are included in the article. It would take a LOT of plants to grow enough to offset the oxygen consumption of even a single person in a closed room with no outside air circulating.)
"The main factor contributing to good oxygen levels is the ventilation rate – the exchange of air with the outdoors."
(The article also includes links to supporting references.)
(Biography of author:
Bio for Robert Pavlis
https://www.gardenmyths.com/media-kit/#bio )
This author is a chemist/biochemist, and a Master Gardener, and he does seem to have his references in order.
(My conclusions from what I've read about this:) Except for the fragrance of some plants, it would seem reasonable to conclude that houseplants have mainly a psychological effect, not a biologically significant effect. Also, an indoor environment in which plants thrive (well-regulated humidity, clean, free-flowing air, outside air exchange, etc.) is also an indoor environment in which people do better, and things like black mold and excessive airborne dust will not be thriving. We also like bright daylight (or the best indoor simulation of it we can put together), as do most plants. So thriving houseplants may be more of an indicator of good indoor air quality (and an attentive indoor gardener) than a cause of good air quality.

I used to spend a lot of money on house plants which my black thumb quickly killed. Even cacti and other stuff which is supposed to last. (I don’t think I kill rocks).

Now my question is whether they make a measurable difference in oxygen and CO2
