You have your N-95 filter masks. Now how to you get the maximum use out of them?
They’re “disposable.” But can you safely re-use them?
Does anybody have “enough” masks?

DUST?
So, when DO we change masks? Well… The tiny virus-containing droplets take a LONG time to actually plug up a filter mask (unlike dust or smoke). The mask will still filter for quite a while, but with virus droplets stuck to it, it’s now dangerous to put near your eyes, nose and mouth.
Thought exercise: Imagine that you’ve smeared the outside of your mask with “deadly poison dust.” Now, if you aren’t really, really careful when you’re putting it back on you’re going to get dust RIGHT in your eyes! (And that’s an already known avenue of infection.)
Yes, you could just put your (non-vented) goggles on first, and THEN the mask. But it’s still risky. And, yes, it’s true that wearing SOME mask, even a mask you’ve already worn, is theoretically better than wearing NO mask because you’ve run out of them.
The other problem is what to do with a potentially contaminated mask in between wearing it? It’s smeared with “deadly poison dust,” remember? Where do you store it? How do you keep the dust from getting disturbed and getting on the other side of the mask, the clean side?
In a perfect world you’d have a $500 pile of masks and discard them after even one wearing. That’s why we call these “disposable” masks. But if this becomes a pandemic in the US and there are sick and contagious people out and about for more than a month (easily), you won’t have enough masks to do that, while going about your ordinary routines.Continue reading“When Do We Change Masks? – Part 1, by ShepherdFarmerGeek”
