There are lot of KN95 mask supplier in this period. The KN95 masks are of different qualities in the market.
We found that many manufacturers buy certificates to qualify for export. Hope clients would pay some attention when purchase by large quantity especially for sale. The most obvious clue is the issue date of certificate. The certificate may be fake if the issue date is Febuary or March in 2020. To achieve the CE certificate, samples need at least one month to be posted to the laboratory. Which means the samples have to be sent out on January to achieve the certificate issued on Febuary. But we were in Chinese Spring Festival vocation on January. So the certificate issue date will be a strong clue to clarify the factory quality. Please also note that this criterion is not universal.
