The Newer, Cuter DIY Filter

My collaborator Gus Tate suggested we work with our HEPA manufacturer to get smaller, square HEPAs. Now we’re convinced the DIY filter just got a lot cuter:

Can we try for cuter yet?

How about taking a quiet little computer fan and adding one of those elastic-rimmed circular filters that you put on a gasmask-style respirator? The elasticated ones seem to be particle filters; maybe a carbon filter could go inside behind it.

OK, it would be smaller-throughput, and you’d have to change it more frequently, but it would be very cheap and you could run it off a solar panel. Could you possibly test such a thing?
