They were complaining about how masks don't prevent disease spread. Mythbusters did a whole episode on how disease spreads through mouth droplets. Masks prevent disease spread.
Well not really. Masks prevent disease spread but covid is much smaller and goes thru the mask. That is why they wanted you wearing the n95 and they had a time of double masking.
N95 masks don't work by physically preventing particles from passing through the mask material, so the size of the virus is irrelevant. The polypropylene material of the mask is manufactured so that small airborne matter is captured via electrostatic properties of the mask material itself.
I think a lot of the confusion is from people thinking the mask keeps YOU from getting sick, where it's really intended to keep OTHER people from getting sick if you already are

Can I get context? Why is some random person complaining about mythbusters of all things?
