how long do these masks last for? Someone told me 8 hours but that seems retardedly low.

Why bother wearing that? Are you old?
Chase Perez
they should be burned after every use
William Perez
It's 8hours and it should not be reused
Wash your fucking hands and avoid (sick) people and you are good.
Hunter Torres
least a few days, even weeks....
William Harris
This is the requirement for using them for work. Medics, dusty workplaces, etc. They didn't instantly go to shit after 8 hours.
If you are not in a super dusty environment, you easily get 24-36 hours of filtration. Another 8-16 hours of partial filtration.
Remember dust masks and filter cartridges are 'always on'. When not wearing it, it still collects dust. Keep them in a Ziploc ba between uses. You will get weeks out of 1 mask.
Isaac Flores
user, if the scientists, the doctors and the professional say it's useless and dangerous after 8hours, trust them.
But you are free to do whatever you want.
James Clark
anything with a vent like what you posted is about as useful as covering your face with any old fabric. They're more for use in dusty construction zones than for protection from bio hazardous material
ideally you want a full face mask with a good rubber seal with replaceable cartridges that are rated to stop particulate the size of which that a virus may attach to
also wash your hands and try to avoid touching your face

>Someone told me 8 hours but that seems retardedly low.
If you change them often and sterilize them, they will probably last longer, than if you use one until it starts to stink, before you change.
Respirators lasts longer, and if you put a simple filter in front of the respirator filter, it lasts even longer.
Jackson Butler
>maximum length of continuous use in non-dusty healthcare workplaces is typically dictated by hygienic concerns (e.g., the respirator was discarded because it became contaminated) or practical considerations (e.g., need to use the restroom, meal breaks, etc.), rather than a pre-determined number of hours.
cdc.gov
desu the best way to go at it is to use a faceshield (pic related) so the outside of the mask won't get contaminated (easily)
Jose Peterson
surgical masks like this are more for isolation of bacteria and germs to the user than protection from outside elements
Alexander Williams
Every time you breathe out mucus and bacteria gets stuck on the barrier.
This is why 8 hours is recommended and healthy.
The mask will keep "working" until it's clogged up, much later on. There is no failure risk at this point, in fact, clogged up masks filter better. Problem? you can't breathe through properly.
Respirator filters last longer in part because they're protected by valves, through them air only goes in, never out, so your filth can never reach them.
Jacob Young
>tfw have these but they're useless since I have a full beard
Zachary Powell
correct, I just couldn't find a pic where someone had a shield and an n95 mask on
Justin Flores
Those masks are for fence-sitters.
If you’re really that worried, go all out (pic related) or bug in with your rice beans and don’t go out.
If you think either of those are extreme, then just go the Chad route and don’t wear a fucking mask at all, since you clearly don’t really care that much.
Eli Flores
these are not fucking rated for viruses or even bacteria. They are literally only to be used for dust, paint overspray and other particulates.
fucking retards wearing these masks always crack me up.
>t. certified mold tech
Jordan Carter
I know that feel. I just shaved it down to nothing for the first time in ten years or more. I can get a new beard more easily than new lungs.
Tyler Butler
tie your beard across your mouth and stop being a pussy.
Christopher Clark
It's inconclusive hot well n95 works. .3 microns is enough to stop droplets which are bigger by a good margin, but then there's the 95% of particles thing. The next thing to consider is surface tension will want to get stuck to the barrier, it's not solid particles we're talking about. In addition, and probably the most concerning factor is the lack of a seal.
All of this puts their effectiveness into question, but the barrier itself is bound to at least mitigate exposure.
Please do a little research before speaking.
Aaron Nelson
>mold (a biological fungi)
>technician
Adam Harris
you're stuck in a closed unventilated space full of tons of mold particles in ppm
typical maskfag is not, i really hope no one thinks any kind of mask that isnt a full-face respirator will save them if they are riding in a subway train for an hour with a carrier coofing nonstop, most of them don't even seal
if you're going to be in an enclosed space with possible carriers for an extended period of course you need a full respirator-ventilator-exchanger setup like biowarfare researchers wear
John Turner
How many uses can I get out of a 10 minute subway ride twice a day?
Evan Lopez
It's a particulate filter. It doesn't expire.
The mask will last as long as a) it doesn't wear out and compromise the integrity of the mask; and b) as long as it isn't totally cloggest with matter, which would take months of use in a really dirty environment to accomplish.
Connor Mitchell
Says on the packaging to change them after 4 hours
John Cox
Can kung flu spread while a patient is Asymptomatic? If so, you would be better off avoiding people at all cost for a while.
Samuel Gonzalez
Good goy.
Nathaniel Evans
Get a fucking respirator and do a seal test.
It's still not great to go around using a gunked up mask. The mucus buildup could help the virus stay activated for longer, but this is speculative.
I've been working on this, about to get my HEPA air filter, do a wrap and make a guide for slowpokes who have no options left available.
Owen Foster
the real question is how to sterilize it for reuse
Logan Hill
Yes, have you been living under a rock? not only that, but the viral load is higher in the carrier's nose.
Isaac Long
Until there is much dirt in them it become hard to breath. If you don't use them when working wood, it will be days, if not weeks.
Evan King
There are ways, but without the manufacturer's recommendations you always run the risk of damaging the fibers and reducing the barrier's effectiveness. I wouldn't.
Jack Martin
have 9 masks, cycle them for 9 day surface contamination. alternatively, get a UV light wand and sterilize them that way.
Luis Baker
Masks last forever if you bleach them and dip them into 93 octane once a month.
Ian Sullivan
They're primarily designed for work shifts. So about 8 hours or whenever your dumb ass fucks up the nose bridge
Asher Nelson
You can get a reusable respirator for 20 bucks on Amazon and 8 pairs of p100 cartridges for 50 bucks at Canadian Tire. They will last longer and work better than those disposable pieces of meme shit.
Camden Davis
>t. certified mold tech
Holy shit we've got a BioWarfare engineer here!
Brody Hernandez
They last for months. But you need to have proper doffing procedures so you don't contaminate yourself while taking it off. Also if it gets direct contamination like sneezed at they are ditched immediately in health care setting.
Luke Jackson
That looks fucking hilarious. What kind of HEPA filter is it? A car filter? An industrial unit? Where do you buy it?
Gavin Evans
Yes it does, and it take 2 weeks to get the symptoms.
Nicholas Gutierrez
Link??
Oliver Price
Great, I probably have it.
Lincoln Moore
3M technical bulletin coming through

Joseph Fisher
Do these g string tampons even do anything
If there's a legit world ending super virus hanging out I'm not convinced some paper mask with a rubber band is doing shit
I'm gunna make a hazmat suit out of super duty garbage bags. Fuck this
William Butler
Careful with degradation, but it's the most sensible option when compared to the chemical alternatives.
Another thing, killing the bacteria doesn't get rid of the mucus, which bacteria freaking love and will soon move back in.
No time and no backup masks to spare to experiment.
Everyone who can, for the love of god just fucking get a respirator if you need continuous use, the filters are rated to last a long ass time since you're not breathing on the barrier.
Air purifying filters. For AC or purifying units, lots of material. Check Amazon, they're not that expensive all things considered, since it's hard to repurpose.
And yes, it looks like it looks, but does it work? so far passed all the tests I've subjected it to, next is silicone disk durability and incense for leaks. It's already been submerged and proven to be at least watertight.
Connor Walker
Yes they are called "disposable" for a reason. Ideally 1-time use, at BEST one day. You can't wash it in any way either without ruining it so keeping it around for virus prevention reasons is beyond retarded.
Get a reusable half-mask and sealed eye protection instead. Those last until broken (at the rate rubber or silicone degrades, once the seal is broken they can't be used anymore. Straps may break but you can easily repair them), and the particulate filters each last for half a year or easily more if you don't live in a poluted place, if you get ones with a plastic cover you can desinfect them. The mask can be fully washed, even submerged in a bleach solution.
Even official 3M documentation states that each pair of filters last for an entire pandemic wave, and the only reason you'd discard them is for safety contagion reasons, not because the filters clog up too fast. In any case each pair is only $6, if you want to be extra autistic get 7 pairs and rotate through them each day so that even if the virus gets trapped in the filter and you're worried about it, it'll die before the next time you'd use that specific pair of filters (AKA a week).

Pic related is the 3M 6000 series, has a rubber seal. Get the 6500 or 7500 series for a better/more comfy silicone seal and better disasembly & ease of cleanup, they cost between $25-35. The best filter for this situation is the 3M 6035, just particulate protection + plastic cover for rain protection and being able to desinfect the surface - you don't need any bigger filters with activated charcoal (gas/vapor protection), it just adds weight and bulk for no reason.
David Morris
that is if you're continuously working in super dusty environment those masks were rated for you can stretch it a bit trying to filter out virus from normal air
just throw it away when you literally cant breath out of it anymore
Hudson Sanders
depends how contaminated they are. if someone if coofing next to you then you may want to take it off and burn it after an hour. If your not in contact with anyone sick and your just wearing it be extra careful than a few days. Any mask is better than no mask tho. If someone sneezes next to you and you have no mask its GG WP.

Time to wash our hands alright -
off the whole big pandemic BUllshite
Isaiah Wright
Listen to this guy. US version of that filter is 7093.
Evan Powell
Wear it in reverse
Adam Jones
If you are infected yourself this will prevent your coofing particulates from spraying everywhere
otherwise, they won't protect you from airborne diseases
Alexander Wilson
That respirator has an exhalation valve, moron. It doesn't filter your coughs.
John Wilson
You are thinking of a surgical mask. This mask will protect you. Hell, doctors dealing with the infected wear this mask
Jace Sanders
Just have to find my filters now. Fuck me, the whole "plauge every 20's" thing wasnt just a bullshit meme.
Dylan Martinez
Why do you protect others. You must of got it from somewhere.
They infect me, I'll infect them. You risk my family I'll risk yours.
I don't believe in the nigger tier society nor in god or judgement day.
Logan Howard
>anything with a vent like what you posted is about as useful as covering your face with any old fabric
the "vent" is a one-way valve, moron leaf
Zachary Kelly
1 time use. 8 hours seems about right.
Justin Green
whatever helps you sleep at night, I guess
Liam Adams
Ok, good to know! Good luck making it work. It kinda looks like one of those Chinese knock-off gas masks on aliexpress.
Zachary Mitchell
No one properly wears them. They should be thrown away soon as you take them off.
I always see people have them hanging around their chins acting like the virus magically disappears from the outside of the mask when your away from people. you all are fucking morons.
Noah Cox
I trust my safety standards to be higher than literal bugmen.
Here, don't have a better picture, I am using an improved design know but it should help you understand how a pressure valve works.
It opens with pressure, air goes in a single direction.
If you see someone wearing a valved mask don't think it makes YOU any safer.
Owen Clark
How long do they last? Depends on how you use them, and how you sterilize them. What will I do? As someone who knows what the fuck he's talking about. I'll give you an idea.
Say things are bad where I live (and it's getting there). I need some specific item from the store. I go to the store with my 95 on. I walk in I grab some shit. I pay. I go.
I take my mask off as soon as I'm in the clear. I take it off properly. I put it in a ziplock bag. I slather on some hand sanitizer. I drive my ass home.
Outside my house I have a 5 gallon bucket. The bucket contains about 1 gallon of 80% cold water, and 20% bleach. I take my ziplock and open it slowly. I put the mask in the solution.
While the mask sits in bleachy water. I dispose of the ziplock, carefully. I return to the bleachy water and put my hands in it and gently/ lightly work the mask a bit. I take the mask out after about 5 minutes in solution. I take the mask into a second 5 gal pail that is about half full of cold ass water. I rinse the fuck out of the mask, gently. I hang it from a tree branch or something. Let it dry. Mask is now decontaminated and ready for next use after it dries.
You can repeat this process a few times before the mask is fully fucked. It will get more and more fucked, the more times you do this. 1 weekish.
Crucial: It must be a quality 3m or equivalent. Not paper shit. Paper will be fucked instantly. IT MUSH BE COLD ASS WATER, for both bleach and rinse cycles. YOU MUST RINSE WELL OR THE BLEACH WILL HURT YOU! Air dry only! No heater drying, give it time.
I hope this helps you.
N95 is probably the only mask I'll use during this shit, hopefully. These masks will help you in a light exposure scenario. Don't expect it to do you a world of good if you put yourself in the middle of the Wuhan ward at your local hospital for 12hrs.
>The guy who has everything short of pic related on hand, but will probably only use 95's. I'm hoping it's all I'll need.
John Rogers
Stop spreading this idiotic meme, there have been literally dozens of studies over the last decade proving how both N9x and even surgical masks reduce influenza transmission rates drastically
If its true for the flu, then its going to be roughly true for coronavirus as both are transmitted in the same way via respiratory droplets.
This is another retarded meme. Surgical masks are virtually as effective as N95 masks for stopping flu transmission. Again, we have no reason for thinking it should be any different for coronavirus
Key word for the mentally retarded: "effective" =/= invulnerable
