Finding N95 masks made in the US might be harder than it sounds. Pre COVID, most where made in China and they still are today. The one pack of 3M N95 masks I have from before the COVID does state “Made in the USA” but also states “with internationally sourced materials”. No way of getting away from it completely. The mask is only as good as the material and the manufacturing, seems we have a hard time managing both in this case.
The KN95’s are comparable and were more readily available when Fauci locked down the N95 supply for the medical industrial complex (they should’ve had their own stockpiles beforehand). He then lied and told everyone cloth masks were okay, which they weren’t. Some people got sick, some died and now no one trusts masks or Fauci…understandably so (he’s a lying, grossly overpaid, little rat faced bastard, but I digress…). The issue was that greed hitched a ride with the COVID and a number of KN95s shipped to the US initially were not up to the standard. A blatant attempt to cash in on the misfortune of others. There was a website listing all offending manufactures after it was discovered. While I understand the distrust, if you buy good KN95s, they will work as well as the N95 masks.
It’s all about particle size and cloth masks only work for COVID if someone is spitting gobs in your mouth, the weave of the cloth is too large to filter anything significant.
