I have had some copper infused things for knee issues
and even copper infused socks..dont remember why i got them
seems like there is an issue with washing..at least the socks...and it can wash away copper or something ...cant remember
so could be an issue when washing the copper mask from Israel or the microbe mask from under armor
[[can wash away copper or something ...cant remember

well the one article i read on the Israeli masks said they can be washed 100+ times and still be just as effective- Don’t know if it’s true- perhaps just selling hype- but perhaps not- think they have to be pretty careful about claims these days-
