From the post:

>For this post, I tried to measure the performance of my DIY air purifier, the Corsi-Rosenthal box. I wanted to compare its performance against natural ventilation, and commercial ones like the Levoit 400s home purifier. The main metric I needed to beat was the clean air delivery rate (CADR), which is how much ‘polluted air’ is filtered in an hour for a given type of pollutant (like smoke) - it has units in cubic metres of air per hour. Again, this is not a lab grade experiment, but rather a minimal-trust investigation to learn about the subtleties of commercial air quality marketing and measurement.

I don't even want to look at that bookmarks-folder. Mine probably has thousands of projects in it at this point.
