It can’t be zero percent they have to have some positive effect.. it’s not zero.. therefore I won’t complain about the mask it’s not a big deal..
It would be interesting to see how effective some homemade cloth mask is vs. an N95 mask. In fact, I think it's probably very important to know if a homemade cloth mask is providing sufficient protection.
Although surgical masks, which seem to be fairly available after a bit of a wait, must also be fairly effective or healthcare workers wouldn't use those, either.
I saw a number of masks for sale that had N95 filters that claimed to be easier to breathe in. Seen a few of those, and apparently the filter does nothing to the air you exhale, so the mask is useless.
