@Magic14272090 @myrabatchelder @kprather88 They all work. Non-perfect masks "not working" is anti mask propaganda. Some air goes through the mask and gets filtered = less virus in air and less inhaled.
Of course better masks are better and the US could do WAY better on both comms, regulation, and supply of better masks.
@Magic14272090@myrabatchelder@kprather88它们都能工作。非完美口罩“不起作用”是反口罩宣传。一些空气通过口罩并被过滤=空气中的病毒更少，吸入更少。
当然，更好的口罩更好，美国可以在通信、监管和提供更好的口罩方面做得更好。
