KN95 Masks: Medical vs. Civilian Grade

Where Can I Buy KN95 Masks?

Back in April, the FDA authorized the import and use of the KN95 masks for health care settings when the COIVD pandemic started. Since then, there has been a lot of confusion around the difference between the KN95 masks for medical uses and KN95 masks for civilian uses.

Both medical and civilian masks KN95 masks are to the same GB2626 standards. The main difference is the number of certifications and testing that has been done on them. Health care workers who are on the front lines want and need the peace of mind that their masks are going to protect them. Therefore, the medical-grade KN95 masks are tested by the CDC and FDA Appendix A compliant.
