The WWDOLL KN95 Foldable 95% PFE Protective Mask failed because the KN95 standard requires that the mask have the manufacturer’s name and the appropriate technical standard, typically either "GB 2626-2019" or GB-2626-2006,” written across the front of the mask. This is similar to how official N95 masks display NIOSH approval numbers. This mask did not have the required identification on its front.

Agree with two above comments; have been purchasing these for over two years and they always have had this stamp on the front of the mask and on the box or package. They are also the best fitting masks I have been able to find.

Mine have the GB2626-2019 on them too. I’ve gotten them several times and they always had this number on them.

Mine have the GB2626-2019 on them. I don’t think I have ever received any without that.
