It means that cloth fabric does nothing against aerosol. Even N95 masks don’t filter out all virons which can be as small as 1nm and escape the electrostatic charge of the N95. Security theater.
- beeforpork 5y agoNo, this is misinterpretation and too absolute a conclusion. The truth is not found in extremes. Protection is about reducing viral load -- it is useful even without fully eliminating viral load. A cloth facemask does get damp when you breathe through it, ergo some of your exhaled water (= infection carrier) got caught. An N95 mask catches a lot more. You need a bit of viral load to get infected, so whatever reduces viral load will help. It is dangerous to immediately conclude that aerosol transmission makes masks security theater. They do not, they do help a lot.
- thehappypm 5y agoI had a hair on my phone, and I tried to blow it off while wearing an N95. Nothing. Even air itself is substantially slowed through an N95. It's the difference between sucking a viral load at full speed into your lungs, and having it crawl through a barrier at extremely low speed.
