Where are these made?
Hi there. Last bullet of the features:
- Made in China
China makes so much stuff.

Listing says “40-pack,” but image shows one box of “20 pcs.” Does this come with two boxes?
It actually offers to let you choose your own size:
In the Box:* (1) (Your choice pack size) Disposable 4-Layer KN95 Face Masks
Probably in multiples of 20
The “test report” in the product listing states the manufacturer is “Huizhou Yuhao Industrial Co., Ltd.”
The CDC lists a company named “H&Y Industrial” as a manufacturer of KN95 masks.
If those are the same company, the CDC’s test results are very different from the test results reported in the product listing.
The CDC’s report for H&Y Industrial (see link below) states, “The maximum and minimum filter efficiency was 23.70% and 17.00%, respectively.”
The masks in the report you link do not match the ones in our sale.
I received my shipment on Thursday and unpacked them today.
Contrary to the listing these masks are packed in groups of five, not individually.
Thank you for letting us know. I informed our buyer so she can reach out to the vendor.

the attached test report doesn’t give any information. There are lots of writing in chinese but what does is that? still not clear if niosh qualified
I could be wrong but I don’t think any KN95 masks are NIOSH rated. I think it only applies to N95 masks.
(Please note: I don’t work for Woot, I just volunteer to help out here on the forums.)
That is correct. KN95 aren’t NIOSH approved.
Not certified. These are basically counterfeit masks. I bought some before knowing that legit KN95 masks will be NIOSH approved and have a certifying authority stamp on the actual mask. Buyer beware.
Again, KN95 masks don’t get NIOSH approved, only N95 masks. It doesn’t mean they aren’t just as good, it’s just a different rating system. It does not mean they are counterfeit because they use a different system.
Also, the stamps with the certification numbers didn’t go into effect until last July, I believe, so any masks made before that weren’t required to have them.

Correct… NIOSH doesn’t apply to KN95. Correction: " In 2020, the FDA granted emergency-use authorization (EUA) for some KN95 masks due to N95 masks supply being scarce. This included respirators and filters certified under China’s standards: GB 2626-2006 or the most recent GB 2626-2019 . Look for either of these codes printed on the KN95 mask, as this could help identify if a mask is counterfeit or not." Source: How to know if an N95 or KN95 face mask is real to prevent COVID
