Masks
« on: March 31, 2020, 08:27:23 AM »
Someone is selling KN-95 masks from China near me. 60 shekel for 2 or 100 shekel for 4. It says Naisian on them. Are they worth buying? If I have a beard, will they do anything for me? I think they said they are washable? Is there such a thing? Or are they single-use only?

A mask is good only to protect others from yourself in case you're positive or with symptoms or just for precautions. To protect yourself from others you'll need more than that, especially if you have a beard.

Please don't post wrong information. An N95 mask will protect you. A surgical mask is to protect others.

Correct. But he said it authoritatively, so it must be true.
But on the other hand, it wasn't on WhatsApp so it might not be true.
Hmm...What to do?

Not sure how much N95 helps if you have facial hair.

Didn't see anyone mention N95 until your post. KN95 is not N95.
KN95 is Chinese standard and not equivalent.

Question is if you won't, does the N95 still give some level of protection?

It still filters but nowhere near as well.

Not less than a surgical mask.

I will speculate that it is slightly more since what goes through the mask itself is filtered better but not by a tremendous amount.

A surgical mask is basically open from the entire top and sides and welcomes all airborne particles. N95 masks, even if poorly fitted, will be a much tighter fit around the face, and even if not sealed 100%, will significantly reduce airborne particles compared to surgical. IMHO.

Yes but how much I have no idea.
I had to wear respirator masks for many months. Even a perfectly fitted one is not 100%.
With a beard a fitted mask (N95) will still fit better than a surgical mask. It still filters better so based on that I would say yes but that is only a guess.
