I just wanted to say thank you for for including the links to the TED talk and other actionable info (i.e. which plants to buy and how many per person). I have a tendency to see things like the main post and go "oh, that's interesting," but then never really follow-up on them, but knowing that I have a list of which plants to buy was enough additional motivation to make me take the issue more seriously. I'm intending to do a bit more research and get a air quality monitor in the next few days.

Since you mentioned other plants, I am wondering if there are places to look to consider the different plant options. My wife said she "didn't want ugly plants" (if possible), and I was also wondering if there were options I could look at that would be easier to care for (I live in the northern US, so I expect there may be >10week periods where taking a plant outside would be impracticable, not to mention unpleasant since we live in a large apartment building).
