I'm wondering the same thing: I bought in 2014 100 chirurgical masks => they're now expired (and I have ~15 left after giving all others to friends and colleagues after warning them about this) but from what I read the statements were that they can still be effective (not anymore 100% but at least more than 0%, which is more than not wearing anything).
