Factors to Consider When Planning to Purchase Respirators from Another Country, Including KN95 Respirators from China   [open pdf - 214KB]

From the Document: "When a respirator has been approved by the National Institute for Occupational Safety and Health (NIOSH), the user can be confident that the device will provide he expected level of protection. as long as it fits properly and is worn correctly. [...] When possible, NIOSH recommends the use of NIOSH-approved reusable elastomeric respirators and powered air-purifying respirators (PAPRs) as alternatives to FFRs [filtering facepiece respirators]. When a facility still needs additional FFRs, the Centers for Disease Control and Prevention (CDC) and the U.S. Food and Drug Administration (FDA) have determined that other options may be appropriate to protect workers during the pandemic. One of these options is to purchase respirators that meet the regulatory requirements of the countries listed in the FDA's Emergency Use Authorization (EUA). However, due to the current demand, buyers should be aware that an unprecedented number of products on the market do not perform as advertised. The three most common 'pitfall' scenarios include: 1. Documents are altered so FFR models appear to comply with a particular standard, but they do not. 2. Certification marks are counterfeit. 3. Manufacturers' names, logos, and model numbers are counterfeit."
