We've all heard that washing your N95 masks ruins them, but why couldn't you simply put them in a UV sterilization box?
If you're not using them heavily, if you just put one on to go get groceries and stuff like that, couldn't you sterilize it with UV rays and keep using the same mask for months? A trip to the store only lasts an hour.
usa and the Italy at fault.
-american flu lives at 100000+
-america army at Wuhan
-great china economy now.
-we link supply countries europe no thanks.
-china solved American flu.
Why is the responsibility of the world because of bases American not looked at for spread virus?
the rubber would rot in a week
I wonder if microwaving a mask would sterilize it without ruining it?
Dude just have 9 masks in rotation, one for each day and by time you rotate back to first one the virus will be dead
They have discussed this on Twitter, you put them in an oven on low heat for 30 min
Metal nose band make that a no go.
The only safe devices are respirators, masks are just to lull you into a false sense of security
Nuke the gook
You can microwave them for 2 or 3 seconds. It will kill all forms of life in them. I chew tobacco and I just let a little spill out into the mask every once in a while. It stained brown but the Wintergreen and other spice (I think molasses) smells nice and coupled with the nicotine is a powerful antiseptic that will kill any germ. Why do you think our ancestors chewed licorice, Wintergreen, mint and other herbs such as fennel, anise, and wormwood? It kills germs like crazy and keeps your mouth and lungs clean.
N95 IN OVEN 160F FOR 30MINS
DECONTAMINATED WITH NO LOSS OF FILTRATION
I just put them in the vault at work and hit em with high levels of ionizing gamma radiation.
How long do I have to microwave my N95 masks to sterilize them?
someone said throw that bitch in the oven at 160 degrees for a while and you're good. that's my plan.
NO MICROWAVE
OVEN DRY HEAT
They just did some research on spraying them with some sort of peroxide spray and they figured they could reuse them 30-50 times...
Set the fuckers out in the sunshine for a few hours.
SPRAYING LIQUID FUCKS THEM UP
UV OR SUN YES BUT OVEN 160F IS QUICKER
Then you smell peroxide all day and I will tell ya it does not smell great
I put mine in my son's baby bottle sterilizer with positive results.
Duke’s decision to use hydrogen peroxide to decontaminate N95 masks is based on published studies conducted in 2016, but the practice wasn’t widespread, because the industry wasn’t facing shortages. Those earlier studies also didn’t include fit-testing — or the resizing of masks for individual wearers — after cleaning. Duke has now done that efficacy testing in the real world, the university said.
Duke University..seems to work. Google it.
Fuck why dont you actually look this up you NIGGER. yes I also assumed this, it turns out the microwave is not good at destroying virus and bacteria, of course some bacteria but overall I remember its not good at disinfecting
I have Korean K95 with plastic nose band.
Ah yes let me just go dust off the old family UV box from the second home in the vinyards
Also UV my not penetrate inside the mask where virus can be, they dont just collect perfectly exposed on the surface but yes UV should go through some stuff but not all stuff and not always deep,
Gotta find yourself a good gamma source. 100% sterilization guaranteed.
Its vaporized H peroxide...hmmm .not sure you can do that at home
Vaporized hydrogen peroxide
VHP has been shown to be sporicidal at temperatures ranging from 4 to 80°C, with sterilant concentrations ranging from 0.5 to
The polymer material might not hold up to a large number of exposures, UV catalyzes oxidation of hydrocarbon polymers. Same reason plastic things break down after long times in the sun. Most of these masks' filter material will be an electrospun polymer fiber made into a sort of felt
UV
The capacity to disinfect and reuse disposable N95 respirators may be needed during a pandemic of an infectious disease that spreads by airborne particles. Ultraviolet germicidal irradiation is one possible method for accomplishing this. In our experiments, UVGI had a small effect on filtration performance and essentially no effect on flow resistance at doses up to 950 J/cm2, while the structural integrity of the respirators showed a noticeable decrease at lower doses. The strength of the respirator straps was less affected by UVGI than the strength of the body material. Our results suggest that UVGI could be used to disinfect respirators, although the maximum number of disinfection cycles will be limited by the respirator model and the UVGI dose required to inactivate the pathogen.
there ya go fucking right, look we just solved the problem but nooooo, we are at the bottom of the hierarchy

I'm just passing along what one of top doctors in my state told us on TV. You can take it, leave it, go argue with a doctor about it, or eat shit and die. Makes no difference to me, faggot.
i got proper p2 masks with carbon ventilator
industrial microwaves can handle metals
Truthful. There would still be RNA samples on it but they would all likely be dead. Moisture and other contaminants would likely reduce the filtering capabilities quickly though & it would be impossible to gauge when it's time to throw them out. Masks without exhale valves are usually starting to degrade after 4 hours because the moist air clots up the filtering medium and will eventually allow larger particulate matter to pass through.
There's no need to wash them. Use them until you can't breath through them anymore.
Don't touch the inside or edges.
I mean, yeah. There isnt a single downside to sterilization through gamma radiation.
Just use it every 4 days..
When reusing N95 masks, leave a used respirator in dry, atmosphere air for 3-4 days to dry it out. Polypropylene in N95 masks is hydrophobic and contains zero moisture. COVID-19 needs a host to survive–it can survive on a metal surface for up to 48 hours, on plastic for 72 hours, and on cardboard for 24 hours. When the respirator is dry in 3-4 days, the virus will not have survived.
>he doesn't know that it can live on a surface for 17 days
foxnews.com
In theory that would work but all of the affordable UV sterilization boxes are crap made in China and are not reliable. It's probably better than nothing though.
>foxnews.com
That's RNA samples they discovered, not live viruses. It's bullshit that they used the terminology "survived" because yes, the RNA sample survived, but the virus it self did not. The CDC already clarified this in fact.
"A recent documented SARS-CoV-2 RNA was found on surfaces in cruise ship cabins up to 17 days after cabins were vacated on the Diamond Princess, before disinfection occurred.Live, infectious virus was NOT found. The authors’ finding does not indicate SARS-CoV-2 was transmitted from these surfaces."
This bait is a dried out worm on the sidewalk.
I'm thinking of masks made out of furnace filters.. a high merv rating should be pretty damn good. The problem is getting it to fit tightly...
This is what I don't get. Aren't we just fucked for real? How long does it last on clothes? On paper? In enough time, would enough surfaces be contaminated at the same time to where it's just a cycle constantly repeating, of spreading / contamination? Like what are you supposed to do when you get home? It's not like we have a decon station. It's on our car keys and turn signals and who knows what else. What are we supposed to do about this shit?
exactly..it doesn't mean its viable still... if it can't infect anyone..then it doesn't matter.
I wonder how feasible it is to nigger rig a small cyclotron at home
Find an old crt monitor for the electron tube, wrap some big coil electromagnets, and weld some pan shaped metal into dees
Accelerate some electrons into a lead target, and you can produce gamma rays
This. I want answers.
>calling me out on my bullshit

I'm drunk right now, I'm going to cease shitting up Yas Forums and play some vidya now
Goodbye frens
It lasts forever on everything, and you're already dead.
then get 18 masks
saturating your n95 mask in 90 percent isopropyl alcohol doesn't ruin it and it disinfects it.
do your research brainlet.

It’s not even entertaining bait anymore. At least switch it up and get creative faggot.
How long would the static charge on the mask fibers last? Especially when exposed to the elements?
I just learned something finally some explanation, on why they degrade and time span, but still would like sauces
I know I figure it may destroy materials,
100% this.
What kinda fag wears a mask to go grocery shopping?
A smart one.
oh God thank you , actual data, should have source in the image but I bet its real , yes sweet white man testing data

thank you
