@TaylenandKatie Hmmm, surgical masks are not meant to be washed.
Even washing cloth masks over time makes the holes between the fabric larger: https://t.co/37jIulefa9
And definitely can't wash a N95 with soap and water b/c it severely compromises the electrostatic charge / filtering.
@ItWasAGoodIdea1 @davidmweissman They hardly move the needle at all. We don’t emphasize any other aspect of safety that makes such a minimal difference. When you emphasize a measure to be taken, it needs to actually be significant. Vaccines and N95s are those measures: https://t.co/rKA2xEWlom
@etohislife @DrEricDing @AliNouriPhD @shadihamid Masks will trap droplets. Not aerosols.
Masks have pore sizes of 80-500 um or more. The SARA-CoV-2 viron is 0.1 um. Cloth masks have larger pores.

Aerosols of 4.7 um can carry SARS-CoV-2 virons.

@marinavance Very interesting! What is the pore size of the cloth masks in your investigation? In this other paper they were very large (80-500 microns) and the more washes, the greater the loss of efficiency.https://t.co/mOphwSf1fP https://t.co/Jy4JNPRBeq
