It's important to see the reasons for ineffectiveness as opposed to just dismissing. Properly worn, properly handled, should prove some notable value. But different factors can play a role: how old is the mask, how much wear has it had, what materials, how often is it cleaned, is it by someone nearer those infected, etc. Like I can point to some masks I got in the summer that I can obviously tell have lost some effectiveness because they aren't as tight and secure as they used to be. It's not like we've perfected this aspect and the variables can drastically change results.

Still, the main purpose of masks was always protecting others from you, not you yourself.
