World Health Organization states about masks in their guidance, in the context of COVID-19

Quote

There is currently no evidence that wearing a mask (whether medical or other types) by healthy persons in the wider community setting, including universal community masking, can prevent them from infection with respiratory viruses, including COVID-19.

Many people have no any idea how to properly use masks, so instead of the personal protective equipment, their mask may turn into a source of infection. A quality respirator, separately, cannot create a complete protection against contagion, because according to Professor of Infectious Disease Epidemiology David L. Heymann

Quote

Masks could create a false sense of security that could end up putting people at greater risk. Even with the mouth and nose fully covered, the virus can still enter through the eyes.

From what I have been told by some one who I know personally who specializes in studying pathogens, the only mask that will prevent viruses from penetrating is an N95 + FFP2 or FFP3 grade mask. N95 is not enough. A large number of KN95 masks are also fakes.

I would say it's maybe even better than the majority of the surgical masks. Usually, they have 3 layers of protection and this one has 4.
If it really filters 98% of the bacteria (which is more than usual, that's the equivalent of FFP2-3 masks except you can't put it on as FFP.

For anyone interested to buy some masks FFP2 outside of this forum, you can find many on Gearbest, Aliexpress. I ordered some from Germany
The shops are not allowed to sell masks in my country... Better I tell you it's funny getting sex with FFP2 Cheesy

Only "respirators" actually "work" IMO.. (protect yourself)
And must be P-100 or greater/additional qualifications..

But, the stupid face masks they are telling you all to wear are not to protect you, they are to protect others from you..
They keep you from spreading what you have into the air so much..

Respirators, on the other hand, actually do protect you, but do not stop you from spreading what you have to others, for the most part..

"surgical masks" are to keep the surgeons from breathing onto the open incision.. They protect the patient from the surgeons breath..

Agree

Just wach this one .

I had some FFP2 M3s laying around from the time before the virus and when I was painting my gear. Now only 3 unused left.. Those are the best you can use to protect you from inhaling the shitty virus but again, your eyes are unprotected, then no matter the mask you are still unprotected. Unfortunately, the only true protection seems to be a biohaz costume.

There are many reports of Chinese N95 masks being imported into the US that do not filter 95% of particles (as is required to be a *N95* mask) or are otherwise defective.

There is also a lot of suppliers of medical suppliers who have popped up recently that have shown themselves to be unreliable, at best.

I would strongly recommend against buying from anyone selling masks, medical supplies, or anything coronavirus related on this forum.

Seen this one on the Meta board topic https://bitcointalksearch.org/topic/large-number-of-face-mask-selling-threads-in-marketplace-board-5245620 I think it's really better to avoid those sellers in this forum and instead buy surgical or non-surgical masks on trusted suppliers.

There are some discrepancies between local classification and FDA's definition about "surgical mask". As far as I'm concerned, masks with 3-4 layers, one of which is bacterial filtered are generally called "surgical mask". Many products among them fit the discription of FDA product coded QKR - "non-surgical mask".

Besides, in Vietnam, the medical authorities always said that "wearing masks help reduce the spread of the disease" and people have to wearing a mask in public places during critical phase of Covid-19 pandemic. That's may explain why the manufacturer wrote "prevent penetrating from virus" on the package. In this case, I think both Nam Anh Equipment Trading Production Co., Ltd and coin163 did not fully understand FDA's classification and caused the confusion.

From that's link I got many pictures about CE, FDA, and many other packaging from this mask. But I want to show FDA certificate and the packaging only

According to this FDA certificate, the face mask Product Code: QKR with Device Class: Not Classified

Archived

From what I search about the QKR code, it means any face masks with QKR code is Non-Surgical Masks and can't prevent from disease. And only face mask with Product code FXX, MSH, OUK, OXZ with Device class: 2 is recommended and prevent from covid-19 spread

Quote from: https://www.leehealth.org/about-us/community-affairs/community-partners-combatting-covid-19/ppe-supply-needs

Non-Surgical Masks: Non-surgical face masks not intended for the prevention of disease are NOT regulated by the FDA (FDA Product Code QKR). The FDA has issued guidance that allows enforcement discretion (e.g. not explicitly regulated) for non-surgical face masks intended to be worn by the general public or healthcare personnel. In an ideal world, we would test samples from batches of non-surgical masks – BUT, something is better than nothing and the public/staff can wear homemade non-surgical masks outside of isolation areas if permitted by hospital policy.

Honestly I didn't expert about medical things, so I prefer to ask and share your thought about this case. I have contacted coin163 about this and his answer
