How does that prevent Covid from passing through the sides?

They are useless because they cannot possibly filter the virus out of the air that you breathe.
I like the way a member of President Biden's Covid advisory group put it.
If it can't prevent you from smelling cigarette smoke in the room, it cannot filter out Covid, since the smoke particles are on the same order of size.

Unfortunately we're going in circles here, and I'm going to have to bow out. You can believe whatever you want, about basic physics or anything else. It's a free planet, after all.
