dust environment and infectious environment are very different things,
not to mention n95 protect against particles larger than 0.3 micron, coronavirus particles are 0.1 micron.
bacteria size is 0.3-120microns, dust even larger. n-xxx type masks are not made to protect against viruses
N90 is equivalent to P1, N95 to P2, etc - as the ratings go up, so does the filtration ability.
The masks being sold here are P1, so less effective than P2 - I can only assume that they’d last a similar time though. I’ve worn a P2 on a fireground for >8 hours with no problems.
i’m not upset they are selling them for 2.70, still 5x more than they worth, but demand\supply creates the price, 27 for one would make me upset, but 2.7 not so much.
When I use to use these all the time at a previous job, the rubber bands are made small length wise until stretched. I use to have to stretch them one or two times by hand then wear the mask.
If it was used I would think the mask would slip right on without much resistance unless you got a small head. New they will be uncomfortable tight unless stretched a little. I really hope know one is selling used one’s and that’s just a joke.
Misinformation abounds, and has caused much of the panic issue. I suggest research.
The masks are more to prevent coughing germs onto surfaces and to keep one’s hands away from nose and mouth, which is how we get infected. The mask itself will not stop the virus, but keeping your hands away from your face and washing your hands often will go a long way. Read what the World Health Organization and the Center for Diagnostic Medicine have to say, avoid Social Media information as it’s mostly gossip and ill informed.
the only thing that does prevent virus infection is air tank, and full face mask, like those that firemen use, i have one, thou it is almost empty, always wanted to charge it, but never got around to do it, not that i would wear it now, but i wish i did charge it, you never know. now all dive shops are closed,
Wellp, to be fair, hasn’t like (almost?) every recent viral outbreak been traced back to a wet market there? Those’re plague-factories, yet nothing’s ever been done about them, nor will there be anything done about them.
Was trying to find a vid showing one of ’em, and how nasty/filthy they are, but can’t find it.
Food drops on the floor/sidewalk/whatever? No prob, toss it back into the basket. Open crates also on the floor, resting on the same floor people walk on, spit on, effluvium from the “wares” spills on, again, no problem. Let them sit there, wide open. Then stack them with the same dirty bottoms of the crates resting on the “food” that’s on top of the crate below.
Ew, ew, ew. Let’s just say not many of those places would get ‘A’ ratings here.
Hey, I’m still jonesing for Choinese fewd. I’d get that almost exclusively practically every workday for lunch. I don’t blame ’em, but understand some people do.
Then again, I don’t think Italy, etc., are fans, either, but dunno if they’re feeling the hate as well.
