@AstorAaron @Fyodor32768 Pass rates for the better N95 designs can be 90% or higher (of course, all have some pass rate). So someone who hasn't fit tested and has a reasonable fit will probably pass. Someone who definitely failed didn't.
@AstorAaron@Fyodor32768对于更好的N95设计，通过率可以达到90%或更高（当然，所有产品都有一定的通过率）。因此，那些没有通过测试且合身程度合理的人可能会通过考试。一个绝对失败的人没有。
