Re: home dust filtration

How can you even search for this? Google results are not relevant to dust at all:

https://www.google.com/search?q=diy+air+dust+filter

This is a really strong example of how bad goog sucks for long-tail queries.

I've found that tacking 'pdf' onto search queries gets through some of the SEO garbage. For instance I did 'home dust filtration pdf' and found this pdf:

https://www.epa.gov/sites/default/files/2018-07/documents/re...

which cites this paper about deposition rates of different particle sizes:
