Should have pointed out that those KN95s that were below the standard are still completely superior to cloth or typical surgical masks. VERY IMPORTANT TO POINT OUT
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.
But 88.7% filtration is still way better than a cloth mask.
True
@@SpecJack15and cloth mask is better than nothing
Even if the KN95s are below quality, they are still far superior to surgical masks and cloth coverings. We're talking 60-80% better protection
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
They should have filmed this 2 years ago…
@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 😂😂😂😂😂
Wearing kn95 since the start. Practicing handwashing frequently & social distancing. Avoiding useless contact. Still safe in spite of living in the hotbed NY mid 2020
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 have been wearing N95 masks nonstop since March 2020 and have been shamed and given strange looks countless times. Turns out I was right all along.
*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.
Only if 3M not charging arm and leg, we will buy it.
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
surely amazon is responsible for allowing false advertising on it's site. Amazon is making money by selling these false items. Take the Money take the Responsibility!!!
As an essential worker I trusted my KN95 mask to protect me. I spent almost $40 for a box of fake knockoffs. It was one you dissected. How could they continue to sell products they know are not 95% effective ?
I would like to see someone evaluate the comparative effectiveness of masks for people with and without facial hair.
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.
That's why we need WSJ. and journalism..Thanks...
South Korea's KF94 masks should have been tested as they are the most comfortable, reliable, protective masks available today.
Go to his channel he tested tons of KF94
Go Aaron! Great to see your work here.
*I'm not worried about people wearing ANY low quality masks.* I'm more concerned those who don't care about others health and walk around like Covid-19 never happened. 😷😷😷
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.
@@olliea6052 some of us with cancer and autoimmune disease will have to and it is not fun for us. Be kind. Don’t be one of those people who contributes to other peoples suffering. Find Jesus- he will help you.
That host was wearing the 3M aura 9205+ fish style mask that is my favourite comfortable and very effective mask.
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.
Would’ve been better if they also covered KF94 since thats the mask form factor i prefer
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.
Did you wake up from hibernation? This video would be great 2 years ago
Um why not TELL us which one to get and give the dang link??? Shing genius, huh?
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.
Is it possible to list the 6 n95 mask that performed well?
Just get an authentic N95. 3M and others provide information to tell if it is real or counterfeit.
The issue here is mask is not just a regular commercial product, it need to be specific regulated who can sell it to assure the product is legit and meet the health requirements
Pretty nice video Aaron!
What prompted WSJ to think that people living with masks for 2 years would be interested anymore. 😑
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.
KN95 are made in China, N95 are made in the USA. This information is on then 3M website under respirators
Note to Korea, Australia, Japan, and Europe all have different designations for the N95 type respirators.
Additionally, when fitting the ANY RESPIRATOR to your face there should be no facial hair on your face so as to get a proper fit and to reduce any possibility of respiratory infection.
ok more than a year later. these masks do work well but it takes a few minutes to form the mask to your face. they start out stiff but you can form them to your face and they are really comfortable for at least an hour unless you're doing some hard labour of course
How about KN95 and cloth mask used at the same time?
I double up on any mask I use 🤷🏼♀️
There's a guy on UA-cam, who's company is Armbrust. His name is Lloyd.
He has tested masks sold on Amazon and he continues to test them. His goal is to test every mask Amazon sells. He uses equipment that NIOSH uses to test the masks, obtaining filtration and breathability results, passing or failing them for safety. He also has all of the results on his website, Armbrust. In addition, his company sells the best ones. His company has also designed and received approval to sell KN95 masks, which can provide up to 99*/* filtration.
I have hay fever. I wanna dry trim my cannabis without having a asthma attack. Which mask is optimal for my needs?
if the mask is not your size and there are gaps then none of the filter layers mater.
Just for curiosity: What would offer the most protection? A a fake KN95 or a disposable face mask?
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!
A bit late for this testing and report, don’t you think?
So what is stronger the N 95 or the KN 95?
Very informative video. Thank you WSJ!
😂😂 “thank you, corporate overlords!!”
Not professional testing way to use TSI ! Too bad ~
Yes N95 can be tough to wear. For the others, One could double mask (surgical plus N95).
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)
Interesting to see, there are no FFP2 Masks, which counts in Germany as the best
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?
Great reporting, thank you!
Our superhero :
_The Masked Knight_ 😃
Excellent! TY!
What would people expect in anyways?
High inflation is world-wide problem, therefor rising costs. So firms are producing a better than nothing quality of products, and NIOSH puts its stamp on better than nothing products due to high demand. No one takes responsibility, nor the firms are afraid of the devaluation probability of their firms stock prices. no liability here, because we *have to buy their products*.
Avoiding an explanation means acknowledging the fact of the problem.
What's the point, American don't wear mask anyway
N95 masks are very easy to get used to after about three days. At least the 3M 1860 ones I got. They are hard to use while riding a bike and hard to take off. However, it’s not that big of a nuisance while walking around and entering indoor locations such as grocery stores, and I at least feel like I won’t be the catalyst for another person or an entire community’s deteriorating health. I just wish we had more of them in circulation here in Japan.
you wear one riding a bike??? Weirdo
Wheres the mask efficacy information for once it gets moist? From wearing too long....
Do you have tips on reusing n95 masks. Can I put them in a bag and use them 30 days later or can the virus still be on them?
the virus dies after being in a bag for 48 to 72 hours.
Questioning the credibility of the test. How can we know the testing method used in this video is the same standard as the NIOSH testing method, what particle size it is and what is the flow rate? Does the testing complies with GLP? Different testing methods will definitely have different results. The N95s placed in the TSI machine are not well placed (headbands are under the AERO PRO N95) and the testing data is not shown directly.....
Plot twist - masks do ABSOLUTELY NOTHING to prevent viral transmission.
WSJ didn’t do their research KN95 is a Chinese knock off of KF94 and N95. KN95 is not regulated and is made in China while KF94 is South Korean. I’ll say however, N95s are much better at filtration than KF94 but it’s uncomfortable while the opposite is true for KF94s.
I wonder if you will tell us that centimeter is a knock off of inches.
@@jasonzhang3775 I wonder if China will ever warn other countries of a virus when it appears instead of lying to WHO.
@@sams8502 or maybe I wonder if Austria will ever warn other countries of a dangerous man called Hitler when he was just born.
@@jasonzhang3775 Xi Jing Ping == Hitler
Tests have found that manyKF94s have very good filtration, above 99%. Getting tight fit is their problem.
could the filtration efficiency depend on the electrostatically charged layer, and could it be certifiable by a third party
Aero Pro had showed their testing method, which is very different from 4C Air(they also sell masks, are they competitors??)
@WSJ
Great idea but it was a little late. I wonder where all that money went that was supposed to take care of these issues a head of time.
Thank you
Can you please put the names
I'd never buy it from Amazon, you never know what you get there...
If you really want to do test you should add one that government provided too
n95 mask made and sold by wsj is more equal than other masks
He sounds like Bane when wearing the mask
The price of masks on Amazon is just ridiculous expensive compared to other countries
Would love to see results on a cloth mask, that 90% of the people are wearing.
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.
Where can I get some in a small size? I'm an adult who is immune compromised & have a small face. Regular N95 KF94s are too big
I know Savewo have a lot of differing sizes. They're FFP2 (European standard) made in Hong Kong.
What about KF94 mask?
Which particle size are they all using?
good product
Sadly, Amazon seems to be coming more and more famous for "fake" products in general.
KN95s are made in China. (just in case anyone cares)
I'm sticking with 3M and purchasing through more trusted outlets rather than Amazon. At the moment
prices have not been outrageous.
But on a Medical budget it becomes expensive..... What or reusable one's with 2 layers you wash and use???? Save $$$$
Come on you at least get masks from authentic retailers for the test….

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.

If these masks work so well why don't we use them them in paint booths , instead we use respirators?
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.

no, gasses are smaller than respiratory particles

KN95的标准描述的测试方法应该和N95的美国的标准以及国际标准进行评估和比对。我感觉口罩的形状，很重要。KN95便宜是有原因的，他本身的密封性不如3M的。作为中国人，还会略感尴尬。聊胜于无吧。至于缺乏口罩标准和制造厂商名称的口罩，我感觉大概率是假货。GB 2626-2006已经废止，现行强制标准为GB 2626-2019，供大家参考。

He he he hoo hoo
Ha ha la lee lop
I shuddered watching Aaron Collins putting on an N95. His method was grossly improper and could damage the mask and/or prevent a good fit. And by the way, any N95 will underperform if not sized and fitted correctly - and since they come in different sizes and shapes, the fact that one N95 did not perform will on Aaron's face is no indication of it being unsuitable, only that he should try a different size or style.
If you think Aaron's donning method affected the test results, then why did the independent lab come to the same conclusion?
The best mask is NO MASK
