@FinchTH @Rose_Marie_Holt @RidleyDM @jvmlost @coolpix_jpg @cre8iverenewal It wouldn't have to be highly protective like a PAPR (though should likely provide some protection), but if everyone wore one, the filtration would just follow the people. Any room where people gather would be adequately filtered (scaled with occupancy).
@FinchTH@Rose\u Marie\u Holt@RidleyDM@jvmlost@coolpix\u jpg@cre8iverenewal它不必像PAPR那样具有高度的保护性（虽然可能会提供一些保护），但如果每个人都戴上一个，过滤就会跟着人们。人们聚集的任何房间都会经过充分过滤（根据占用率进行缩放）。
