@edsuom @vxgxn Whatever you use on your nose I'd add a room air cleaner if your dentist does't already have them (most don't, of course). Both as layering and because you may not avoid some breathing through your mouth, also possible surface infection through mouth and eyes (if no goggles).
@edsuom @vxgxn 无论您在鼻子上使用什么，如果您的牙医还没有，我都会添加室内空气净化器（当然，大多数都没有）。既作为分层，又因为您可能无法避免通过嘴呼吸，也可能通过嘴和眼睛进行表面感染（如果没有护目镜）。
