2/ "NIOSH has been informed that many legitimate manufacturers in China have been counterfeited. In such cases, NIOSH has no way of verifying which products are counterfeit and which are authentic.
3/ "While the manufacturer listed in the table is shown as the manufacturer of the product evaluated, NIOSH has been informed that some of these are actually counterfeit products.
4/ "Some products with legitimate manufacturer names, showing poor filter penetration results (<95%), are counterfeit products. A number of manufacturers have also informed NIOSH that they did not produce the products associated with their name.
5/ "NIOSH urges purchasers of masks and respirators that may have questions about the authenticity of these products to contact directly the manufacturers and others in the supply chain as needed to verify that they are obtaining legitimate products."
6/ If anyone has advice on how to know when you are getting the "genuine" article, I'm opening to hearing it.
As for me, I prefer to buy American for masks.
