@videomurder @velartrill Cheap mask, the ones widely used, don't really (5-6% protection). They're not magic; they just stop your projection to get to other people... And won't stop revived projection much (simple tissue... no active filter...)
But, of course, the "higher quality mask" (ffp2 and others) do protect you more from others. Those are, sadly, not really easily accessible for now.
So.. it's still a good idea to wear one in any case because we're contagious without symptom at start.
@videomurder @velartrill Indeed they are. I took the time to look at your document (and it's sources, interesting) and... maybe we did not understand each others but it confirm my point (That the protection rate drop dramatically for an wearer with someone who don't have one). But sadly, they are testing with non-liquid, round shaped particle. page 9
The virus complex shape (and from liquid projection) make tissue mask even less effective. But that's an other problem...
@videomurder @velartrill About those cheap mask : "These types of masks may not be effective in blocking virus particles that may be transmitted by coughing, sneezing or certain medical procedures. They do not provide complete protection from virus particles because of a potential loose fit and the materials used." https://www.canada.ca/en/public-health/services/diseases/2019-novel-coronavirus-infection/prevention-risks/about-non-medical-masks-face-coverings.html#_Limitations
I'm no expert.. So... I can be wrong ^^' And I'm not trying to be "right"; I try to stick to the experts ^^'
@videomurder @velartrill Feel free to give other material has they are interesting :D And I'm not like "mask are shit"; I'm more like "Mask are awesome... Please wear one like everybody so we're all safe" 😅 They're only useful when used correctly ^^' Cheers, I stop spamming if you don't intend to respond.
