>>a solid practical understanding of disease transmission really does make life so much better.
Hear HEAR. Also hear hear on the smoke side - I made my first CR box for wildfire-smoke reasons, but it's been amazing for other purposes, too.
I've been slowly replacing my older, noisy air purifiers with the small, quiet, powerful HEPA units that got popular around 2021. One now lives by the stove, one in the bedroom, and I'll run the CR box on bad pollen days even if it is noisy, because it moves a HUGE amount of air.
I was bemused to note, the other day, that it is no longer as cost-effective to replace all four of the furnace filters for the CR box rather than just replacing it with a commercial unit, and buying the filters for that. Over the course of years, the commercial unit wins, and is quieter to boot.
