This paper shows that cloth masks, at least of the kind they used are significantly less effective than N95 masks, and the amount of the penetration of the material depends massively on the size of the droplets https://academic.oup.com/annweh/article/54/7/789/202744 … Any studies on typical COVID19 droplet size?

Most of the studies I've read stated that even 30% effective face masks worn by both parties almost entirely reduce the risk of transmission in low risk settings. The main factor is that both parties need to wear them. (Non-clinical settings) https://arstechnica.com/science/2020/06/modeling-the-impact-of-face-masks-on-the-covid-19-pandemic/ …

11) Before anyone says this study’s conclusions are wrong about masks, there is ANOTHER arguably much better study on masks today. Much richer data:
