not0-e I am NOT advocating for mandating use of masks- I am only posting about that chart because some folks who want, or need to wear them because of sick elderly in home, or because of compromised immune systems, might want to know if homemade masks do anything at all- there’s a lot of conflicting claims out there- but if you have a compromised immune system, or have loved ones who do, and you feel you want to try to help keep them safe, then some masks are better than others for doing so-
I am basing my choices on the information of personal friends and relatives in the medical industry. I place no value on comments online from folks i know nothing about. Please do not take that personally.
