I would doubt that there have been any contaminated masks. That is too much. Time alone kills the virus. There are however reports of Chinese masks, like many other Chinese products, not living up to the claims, so you may not get the quality of mask that they tell you it is. It may not filter like a 3m n95 mask. |

I got some of those from a hardware store the other day.. The ear pieces do have stretch to them but they don't fit as tight as the 3M.
Does anyone know if they're g2g? |

According to the PDF above, the KN95 mask they tested had ~8% total inhalation leakage due (includes both fabric and face seal leakage). NIOSH rated mask said N/A, not sure why. Presumably NIOSH N95 would be < 5% TIL.

From the text of the PDF above: "Based on this comparison, it is reasonable to consider China KN95, AS/NZ P2, Korea 1st Class, and Japan DS FFRs as "equivalent" to US NIOSH N95 and European FFP2 respirators, for filtering non-oil-based particles such as those resulting from wildfires, PM 2.5 air pollution, volcanic eruptions, or bioaerosols (e.g. viruses). "

I would not trust a KN95. China Asshoe!
Im in medical and have some samples on my desk that don't excite me and I dont trust the documentation that comes with. If I order 1 million at a time I can get them $1.50 each delivered..... |

https://wgntv.com/news/coronavirus/illinois-spent-17-million-on-masks-that-are-now-being-recalled-in-other-states/ Our governor fucked up bad!
"That includes many KN95 masks bought from China, which the Centers for Disease Control and Prevention said earlier this month was an acceptable alternative to the United States approved N95 masks. State spending records reveal Illinois has already spent nearly $17 million buying the KN95 masks."I get it,something is better than nothing but... |

Other countries have rejected KN95 masks for being defective.

I’ll pass along my 2 cents.
Unless you are going to be properly fit tested why bother buying any type of N95 or “equivalent”? AGM use to have fit test kits for about $250 if you really feel the need. I’m a healthcare worker and we are annually fit tested. I fail and use a PAPR for for over 20 years. Lots of people fail. Male, female, short, tall, big or small. Some people can’t get a good fit or just can’t smell or taste the agent without the N95 even being on. I wish I could use a N95 because of the added length of time it takes to clean the PAPR every time I leave a room. As always YMMV FB |
