Those scrub the air of pollutants. No way they lower co2 sufficiently though. Plants reduce co2 by growing. Which they do....slowly. By contrast a human will spike the air in a room quickly by breathing.

  That's interesting, I was just linking the article because it was talking specifically about co2 and NASA recommendations. In fairness, it didn't give any hard numbers on what to expect.

    I think the author of the piece just made a poor inference. Air cleaning isn't necessarily the same as lowering co2. That said, seems there are some succulents that do most of their co2 intake at night. Those would work best for co2. But you would need....at least 30-40 of them. Opening a window, by contrast, works extremely well, and quickly. However, this requires non-polluted outside air. Else you're exchanging lower co2 for pollutants. https://gerrieswart.com/2018/09/06/using-plants-to-improve-your-sleep/ https://gerrieswart.com/2018/09/06/using-plants-to-improve-y...

      Opening a window is just a bit too expensive in the -20 degree weather we're getting around here right now :-)

        I don't think a tiny crack makes that much difference. I also live in a -20 area. Also the colder it is, the easier venting happens, so a small crack has the same effect as having the window open much more in summer. I can't remember the total, but I recall seeing a calculation about this and it didn't amount to very much energy, especially if the bedroom heat isn't on super high. Anecdotal, but I've heard the Germans often tend to keep a window open a bit year round, and I know my grandma did even in winter. She was pretty frugal too.

        Air out with windows wide open for 5 minutes a couple of times a day. The air will cool down, but your furniture and walls will not cool down, so the air will quickly warm up again.

Most plants actually use oxygen at night and will increase the level of CO2 while you sleep. The exceptions will be plants that use the CAM pathway [0] - succulents mostly. 0. https://en.wikipedia.org/wiki/Crassulacean_acid_metabolism https://en.wikipedia.org/wiki/Crassulacean_acid_metabolism
