Don Milton’s examples of droplet differences are a little high class. If it helps anyone else, I find it useful to think of the difference between hair spritz and fine hair spray. If it’s L’Oréal Elnett we are screwed. If it’s Pump it Up we are less screwed.https://twitter.com/miketuritzin/status/1289093700132380674 …

Use a HEPA filter at the very least. It's best if you can just replace air instead of filter and recirculate; that's not exactly effective here in Texas in the summer. Also, the downside of using UVC for sterilizing the air is ozone production (in case that was a thought...) :/

The most recent 3M respirator guidance (Technical Data Bulletin #174) omits this figure; it's from the older 2009 revision. Important takeaway is the part on the right showing droplet sizes from a sneeze - you want a filter effective from 0.1 to 10 micronspic.twitter.com/fMa0y20GA4
