@Megan80irving @gregggonsalves I don't do this, but it is possible to keep the mask on and briefly pull it up or down between bites, even with an N95. Presumably you'd get less dose exposure that way even if >0. I know someone who does this. Does it work? No idea. Has so far. N=1
@Megan80irving @gregggonsalves 我不这样做，但是即使使用 N95，也可以保持面罩戴上并在两次咬合之间短暂地向上或向下拉。大概你会得到更少的剂量暴露，即使
