    Mostly the blue standard ones or the medical mask. Only got Covid a couple of months ago when it was largely deemed ‘gone’ over here (it never left, of course).

      Neither of those work. You need a rated mask. The US standard is N95 - Filters 99.95% of particles of I think 2.5 microns, and considerably more above and below that number. The KN95 standard I believe is Korean and has a similar filtration level. I don’t know what the equivalent EU standard is.

      But medical masks only filter about 40% of the material we’re worried about, and only if they fit right which they mostly don’t.

      I’m sure you’re probably aware that the surgical ones don’t protect you much, they’re mostly a cheap and easy way to keep asymptomatic infected people from spreading the disease to others. If everyone was doing surgicals, it’d be great. But if you’re the only one who masks, they don’t filter for your too well.

      N95s and FFP2s have a long history of development, they’ve been protecting workers from dangerous dusts for decades, and the science of how they work is really solid. Again, please ask for my sources if you’re interested.
