There's a difference between face coverings and ppe masks right?
Definitely. PPE masks are tighter fitting and have a denser filtration mesh. I've got a stash of very-timed-out N95 masks which I use for metalwork, to stop me having black bogeys and a tight chest after a few hours polishing fillet brazing. The fit is much tighter than my Covid masks, and the filtration material is much denser. They are much less comfortable though, due to the metal nose strap and tighter elastic.

Masks became big in the UK about 4 weeks ago when Trish greenhalgh started talking about them. As a leading light in ebm, and author of "how to read a paper" and other maizeballs bits of being a proper science type while also doing some doctoring, they started to advocate the use of masks. And started the "look, other countries do it, this disease is spread by droplets/respiratory, we should try a barrier method. We don't need a clinical trial for this." And off it went on twitter and now we're here.
Wearing masks/ coverings has also increased asmore factories have built up capacity I'm guessing? And more people are out and about through necessity. There's a difference between face coverings and ppe masks right?
