> the poor messaging around masks. Your advice is going to kill people. > I for one have been double masking n95's for a while. 1) You don't have the equipment to check that those are actually N95s that meet the spec 2) You don't have the equipment to do a correct fit-test 3) Modifying safety critical equipment is dangerous. You haven't doubled the safety, you've made these masks less safe. I'm pretty sure you're not wearing the masks tight enough.
