Dr Michael Lin, the author of that PDF on COVID that was posted here a while ago had this to say: "A T-shirt is 79% as effective as a surgical mask. So if someone is coughing next to you and you can't escape, breathe through your shirt sleeve. Any filtration is better than none." [1] https://twitter.com/michaelzlin/status/1241052444798279680 |
