Hello WagTheSam, thanks for a good write up. Can I just ask, what air cleanser did you get? I am thinking of trying this, I don't trust my apartment buildings air vents. What is the gain compared to just opening a window - if you live in a not too toxic environment?

Opening your window during pollen season will wreck you, if you have spring allergies, for example.

  Yes opening windows brings in dirt and car fumes and pollen. AC and air purifiers much better for environmental health

A DIY Corai-Rosenthal box would be the most cost-effective one. https://www.brown.edu/news/2022-12-23/corsi-cubes-study https://www.brown.edu/news/2022-12-23/corsi-cubes-study

AirPura is one of the good ones: https://www.airpura.com/ https://www.airpura.com/ I have one and it felt nice, unfortunately because people smoke in the building I live I can't use it since the smell collects in the filter very quickly and they are expensive (but last a long time if not for the smell). A bunch of carbon could help with that but a) I try to avoid stuff from low wage countries as the carbon is (but not the rest of that particular air purifier as far as I could tell) and b) hopefully I can just move in the not extremely distant future. There are a few others as well, look for the better quality filters ("SuperHEPA" as AirPura calls them). As I understand it, the small particles are the ones that aggrivate allergies the most and that is exactly what the higher quality filters are better at. Only a relatively few companies have those better filters, IQAir is another one. It turns out the name HEPA doesn't mean anything for consumer filters, you need to look at the specs.

They are all about the same. What you want is flow rate. Meaning 99.9% efficiency high end filter is not that much more than 99%. But if air gets filtered 2x vs 5x every hour then the 5x worse filter will probably be better So just make sure to not place the air purifier in a corner, but more central. And turn it up to a higher power. Or run your AC fan continuously
