You absolutely can take off and reuse a mask. Ideally one should be replacing it daily. But don't let perfection be the enemy of the good.

But the media mentions it like its the only solution.

The scientist in this article also critiques the government for lack of reporting and failing to give boosters to most adults, so I don't think this is fair.

Dunno, but the vibe on this comment is "I'm not gonna wear a mask because it has to be perfect, so I'm not going to bother." Sorry if I read this wrong.
