@LisaForKansas @wsbgnl It CAN be, but honestly I've seen many people not even bother with the nose clip. Their fit factor is definitely terrible. They're wearing a N95, KN95 or similar without any mandate, so their intent is to try to be protected, but without good information, not succeeding much.
@LisaForKansas@wsbgnl是可以的，但老实说，我见过很多人甚至不用鼻子夹。他们的健康状况绝对糟糕。他们在没有任何授权的情况下佩戴N95、KN95或类似产品，因此他们的意图是试图受到保护，但没有良好的信息，不会取得太大成功。
