They at least filter out light.

I wouldn't say they are superior to surgical masks because both don't fit as well as an n95 and a surgical mask filters way better than this counterfeit

@@bullymaguire632 a surgical mask filters better? jesus christ what planet are you on???

Krypton maybe 🤷‍♂️

The best mask is the one that a person is willing to wear, and actually puts over their face (not chin). I like KN95s and KF94s. I still always wear a mask when I go out, or if someone visits. I have not caught Covid, so I must be picking out good quality masks.

True

@@SpecJack15and cloth mask is better than nothing

KN95 is actually more practical cuz it block out oil particles. And virus is actually RNA particles, which is tiny oily substance

Sources?

Reactionary BS.

@@jal8298 viral particles are water based since they come from peoples mouths and throats. The particles are not just virus, they are virus in water/saliva

Surgical masks are 70% filteration

@キューティ・プラス Actually, there is a gene in the East Asians that makes it harder for the covid virus to replicate. That is why the surges are so delayed and mild compared to the non-East Asian countries. Honestly, covid is a subtle, but unexpectedly highly effective biological weapon against the Western economy and races, even if China entirely unintentionally created it.

Most these masks weren't available 2 years ago tho.

@@mike48084 Sources please?

@@ZY-cr7yg why? So you can say "fake news" lol

Not sure how many have caught covid due to incorrect masks, maybe more on the "hair dressers, full contact sport, politicians being allowed to travel, not wear masks at all - whenever they feel like 😂😂😂😂😂

Look out for 3M 9502+. There is a more expensive NIOSH version but you can also buy the KN95 version for around 25 bucks for 50 masks

Also live in this retched state, don't wear a mask or distance also have not been infected (or well no symptomatic infection anyway)

@@AdamSmith-gs2dv clearly you are proud of your selfish actions.

I wore 4 layered sweat pant material. Nothing. No flu or Covid or cold. Did the same with distancing and not touching the face. Thinking I want to mask up whenever I go into the germ riddled public.

@@Person-mh6xq *welcome to the real world people do what they want. Stay home till 2080 if u want nobody cares.*

@@AdamSmith-gs2dv You are a dispicable person!

I do believe that I'd read that's been done, previous to the pandemic, as N95 testing, and they have found that to get the quality seal that NIOSH is testing for, that facial hair causes a problem. I don't have links to any studies right now though.

@@JoshuaEfron For decades NIOSH and OSHA have demonstrated that as little as a single days stubble can interfere with a good fit.

Diameter of human hair is about 25 micrometers, vs virus at about 0.1 micrometers, so a thickness of just one hair is creating a hole.

You know what makes a great seal is a plastic bag. Stick it on an zip tie it. You will achieve an absolutely 100% sealed environment

Too many variables. But yeah, facial hair can interfere with a good seal.

*Now you know Jesus felt* teaching the truth, and yet his own people humiliated him and killed him.

Turns out you're just afraid. An keep staying that way irrational

Idiots ridicule a moron. Wow amazing!

I've been wearing my N95s since April 2020. Everyone thought I was nuts too but my family is the only one I know who hasn't contracted covid yet.

Yeah you were right all along.

😂😂 “thank you, corporate overlords!!”

Go to his channel he tested tons of KF94

Same! Aaron covers all of these in his other videos.

its embarassing that the didnt even cover FFP2s and KF94s those 2 are more similar in regulation. and kf94 is now more standard in asian countries.

Agree. The major media outlets don't seem to know about KF94s or are intentionally not reporting them. They are some of the best fitting masks because they have different sizes. One size fits all doesn't work for everyone.

Eno Shima His channel has reviewed tons of KF94s on his personal channel.

@@solarmoth4628 thats why i said its embarassing they didn't cover it.

I bought this mask from a legitimate, authorized 3M reseller and it had a very strong odor! I contacted 3M. They said they were aware of some odor reports re some of their respirators, including the Aura 9205+. They said the odors were from “adhesives and additives” used in the 3M manufacturing and storage process. All I know is, I could not tolerate the odor, and I was worried about harm to my lungs having that odor right up against my nose for hours at a time. The masks sat airing out for 5 days yet the odor was still noticeable. I had to throw them away.

WSJ probably don't want to, or can't afford to be seen as actively promoting specific brands. If you go to Aaron's channel, you can find a lot of talk about specific recommendations there.

the virus dies after being in a bag for 48 to 72 hours.

Just get an authentic N95. 3M and others provide information to tell if it is real or counterfeit.

a fake N95 won't block 95% but at least will block more than 70% of air particles if fitted well while disposable only block around 30% of air particles because they are literally made just for doctors and nurses to be protected from splashing & large particles droplets like blood or saliva not to filter or block very small particles in the air.

If it is a FAKE KN95, you have literally no idea how poorly it will filter.

There was this research that showed a fake KN95 filtered *10%* of particles. That's even worse than a cloth mask. Usually you can do a little google search and find the CDC/FDA tests on the KN95s (KN95s aren't NIOSH approved)

@@AshmewStudios is true, for it to filter 10% has to be one layer like really cheap ones at the store or people cutting their clothes to make them, the best way is to cut them and make sure they have at least layers even if that won't guarantee it will prevent 95% to go through it.

@@AshmewStudios Thank very much for the information Ashmew!

Wear a mask forever then.

Paypal me ur money if you care about me

how do you know what other people care about? I don't wear a mask and I have never gotten covid. I follow real science and common sense. people wearing masks outside and in their cars while driving alone and then trying to shame others are not helping anyone.

Pffffffffft whatevs. Germany isn't even really a _country_

Genuine FFP2 are easier to breath though too.

They're doing a US China comparison, FFP is EU

FFP2 is the equivalent of N95, FFP3 masks offer the highest levels of protection, the US equivalent would be N99.

I haven't really been seeing FFP2 masks for sale in the US. They're far rarer than KF-94s. Maybe they're not being imported here?

I would suggest the KN95. I wear one every day. They are quite comfortable. I do not know the best place to purchase them. I was skeptic of Amazon because there were so many manufacturers to choose from (as usual). So, I asked my ex-wife who is a surgical RN to get me some.

@@FATillery so where did she get it?

@@ronlyon4645 From work. She wears a N95 while at work but a KN95 otherwise. I do not know where the hospital gets their supply of masks. I am sure you can get them from Amazon, however, I would stay away from low-priced masks. I wish I could give you more information.

@@FATillery i thank you

@@ronlyon4645 I was just on Amazon looking at them for you. The prices are not bad depending upon how many you want but, I am uncertain of the manufacturers. Perhaps you should do a little research to see which manufacturers might be acceptable. Take care. Be safe.

I know Savewo have a lot of differing sizes. They're FFP2 (European standard) made in Hong Kong.

Real man take protecting theirselves and their loved ones serious and use gas mask’s

@@Beersandsmokes 😂😂😂 you should have one when you go to Ijen volcano 😂😂😂

Try a garbage bag an zipties

I’m in my space suit so it’s all good

There's no need to double mask with a N95. Only double mask by wearing a cloth over a surgical (cloth is tight but doesnt filter well and surgical filters well but isn't tight enough so added together makes it good)

you wear one riding a bike??? Weirdo

N95s are called respirators. But they're designed to stop *particles*, not gases or fumes. There are some disposable N95s that include a carbon filter, but if you have lots of fumes to worry about then you're better with a cartridge-based respirator.

It's about 40%

@@NOT-FINANCIAL-ADVICE. not even close. That’s a joke. Of these double layers air tight block 95% of partials a loose fitting cloth mask wouldn’t stop a thing.

@@imlon2 I'm not here to debate cloth masks by saying they are good, or protective. They are not. But they do filter about 40% of particles. Source Aaron Collins, aerosol scientist. Not saying they stop Covid, because they don't.

@@NOT-FINANCIAL-ADVICE. They helped to slow Covid down. So did the surgical masks I used to wear.

I guess this should suffice that one should not buy it from Amazon.

If you already had covid and shots then your immune system is protecting you well. There are over 100 studies world wide that show natural immunity is better and a new one out shows that if you have had the common cold in your life that protects better than the shots. If you would like links to the actual studies do a search or look in my news lists for Facts Matter with Roman.

You need a hel

I had covid + 3 Moderna still wear KF94 or N95 indoors.

🤣 boost more plz

no, gasses are smaller than respiratory particles

@@grantgibbs4803 Thanks, maybe the perfume section would be a good rule of thumb test. If you can smell the aerosol particles from a perfume , then probably airborne sneeze particle will also get through.

@@rahulbosebose1 Most odors are from molecules much smaller than a virus. Like around 1000 to 1 at least.

@@rahulbosebose1 perhaps...... we would have to know the size of those particles

Entendi porque hablo español, yo tambien pienso que habrá efectos sobre eso. Y no he visto a nadie hablar de eso.

Same reason that children fear their regular dental check up, so they do and say anything in order not to do the right thing, until their simple dental caries become endodontic procedure and caries reach the nerve ending in their tooth. That is the moment they do anything, and I mean anything, just feel healthy again and keep it that way. Somebody said "you gotta learn the hard hard way". Some only learn that way.

Tests have found that manyKF94s have very good filtration, above 99%. Getting tight fit is their problem.
