Required publication by the U.S. Food & Drug Administration (FDA) regarding intended use and other information:
This product meets the performance standard for GB 2626-2019. It has been tested and approved by the Chinese National Medical Products Administration (NMPA). Per the US. Food and Drug Administration, this product is imported as a KN-95 mask as a “compassionate use/emergency device”. Per the U.S. Center for Disease Control (CDC) “non-NIOSH-approved products developed by manufacturers who are not NIOSH approval holders should only be used in crisis situations when no other NIOSH-approved N95 respirator is available. They should not be used during aerosol generating medical procedures unless the alternative is a loose-fitting surgical mask or improvised device.” Furthermore, Non-NIOSH approved products developed by manufacturers who are not NIOSH approval holders are expected to meet the performance requirements if they have been issued a certificate of approval by an authorized test laboratory indicating they conform to certain standards. This product meets those standards. Please visit:https://www.cdc.gov/coronavirus/2019-ncov/hcp/respirators-strategy/index.html#crisis

NPPTL Test Results (published May 18, 2020)
The United States National Institute for Occupational Safety and Health (NIOSH) is the U.S. federal institute operating within the Centers for Disease Control and Prevention (CDC) dedicated to generating knowledge in the field of occupational safety and health for the betterment of workers. The National Personal Protective Technology Laboratory (NPPTL) was established by the U.S. Congress in 2001 to be the division of NIOSH charged with the mission of preventing disease, injury, and death for the millions of working men and women relying on personal protective technologies (PPT) and personal protective equipment (PPE). The NPPTL has completed an assessment for the KN-95 respirators manufactured by Chengde Technology Co., LTD. For test results, please visit:https://www.cdc.gov/niosh/npptl/respirators/testing/results/MTT-2020-160.1_International_Chengde_KN95Folding_TestReport_Redacted-508.pdf
Methodology: Thirty respirators were submitted for evaluation and tested using a modified version of NIOSH Standard Test Procedure (STP) TEB-APR-STP-0059. Only particulate filter efficiency was assessed. The results of a filter penetration test can only be used to provide a check of the product’s filter efficiency. No conclusions can be made regarding equivalency to N95 products that are NIOSH approved. These assessments were developed as an assessment of the filter efficiency represented as certified by an international certification authority, other than NIOSH, to support the availability of respiratory protection to US healthcare workers and other workers due to the respirator shortage associated with COVID-19.
