Wow, corona viruses are ~0.1um in size, maybe a bit bigger. HEPA filters of appropriate quality then should trap many of the viruses. Thanks for the heads up!

- bluGill 6y agoTrue, if you must have an indoor gathering these days you should have a few HEPA filters scattered around. Nothing is 100% stop transmission but every little bit helps.
- fossuser 6y agoEven smaller stuff gets bounced around at that level via Brownian motion: https://en.wikipedia.org/wiki/Brownian_motion https://en.wikipedia.org/wiki/Brownian_motion HEPA filters can catch really small stuff from this even if technically it could fit through.
- samatman 6y agoEven more than that, because for the most part you're not filtering for viruses, but rather, aerosols: tiny mucus particles which contain the virus, but are themselves much larger, and also quite sticky.
