No. I wrote up the computations explaining why. See http://www.moderndescartes.com/essays/co2_closed_rooms/

Is one person, or two in a closed room overnight the same, or similar to a conference room with say, 15-20 people for several hours? My apologies if you addressed this.

I own a CO2 monitor and it is shocking how high it can get in a house with two people just existing. 800 ppm or more. Outside air is 410. In a car with air on recirculate, it was getting to >1220 ppm, a level that impairs decision making and lowers brain function. I try to drive with air on fresh from now on. I don’t doubt the air in our conference room with 20 people gets super high in CO2 as the meeting goes on, an…

How many plants are needed to counter this?

Depends on the plant and other aspects of the environment, and actual numbers are hard to find. Also, you need the plants to actively be growing; their steady-state metabolism just temporarily captures carbon and then releases it again.

Back in college, I worked on a project whose goals were to examine the effects of closed room vs. fresh air cognition. The solution was a partnership between the Architecture and Biotech departments to develop so-called "living walls" to continuously recycle air. In accordance with this article, test subjects showed improved cognition and memory working in fresh, low co2 ppm air.

I unfortunately do not have a paper but I did find an article about it and it seems they've deployed it in real life with success: https://www.architectmagazine.com/technology/breathe-in-case...

Earlier quoted context omitted.

Could you recommend a CO2 monitor? How did you decide to purchase the model that you own?

Awair Glow is a very user friendly/cheap one: https://getawair.com/pages/awair-glow It has an app (and an API) and monitors CO2, humidity, temp, and VOCs. I like it a lot. For me, it mostly serves as a reminder to open the door for a few minutes before bed and let some fresh air in.

I've been opening the bedroom window before going to sleep but I wonder if it really matters during a normal sleep cycle.

Not sure what CO2 levels that would generate - you'd need to measure to be sure. But my calculations suggest that effects are negligible even up to ~5000 ppm, and many of these studies are boohooing about 1-2000ppm conditions.

I do think this area is understudied. It's just that being afraid of the air supply is such an easy way to nocebo yourself.
