Airlines and some countries are now banning cloth masks. Should the US?

With so much heated debate about the efficacy of masks, you would think we would have clear and convincing details about which masks work and which ones are fairly worthless.

Some international airlines are now banning cloth masks. European governments encourage people to wear medical masks, but the Centers for Disease Control and Prevention dissuades Americans from using N95 masks to ensure there will be enough of them for medical workers. The CDC also does not say to ditch cloth masks as other countries are doing.
