@RaviSutharsan @silverthornn264 @ASlavitt Well-fitted how? There are no resources for civilians to get fit testing, and the free masks are whatever grab bag the pharmacy happens to have in stock (if any) when you get there.
Also, this isn't effective when masks must be removed, e.g. when eating or drinking at work.
@RaviSutharsan@silvershorn264@ASlavitt如何搭配？平民没有进行健康测试的资源，免费口罩是药店在你到达那里时碰巧有库存（如果有的话）的任何一个抓取袋。
此外，当必须摘下口罩时，例如在工作中进食或饮水时，这也不起作用。
