Previously KN95 masks were only available from China, and testing of those revealed that a large number of them do not meet standards for filtration. Sanctuary Systems' KN95 masks meet at least 95% particle filtration efficiency using the same test procedures for NIOSH approved N95 masks. The KN95 masks produced are not N95 masks. Using a TSI 8130 Automated Filter Tester, and following procedures TEB-APR-STP-0059, TEB-APR-STP-0003, and TEB-APR-STP-0007, Sanctuary Systems' SS-KN95 masks meet the same standards required for N95 masks for particulate filtration efficiency, inhalation and exhalation resistance. Additionally, the SS-KN95 masks pass Level 2 ASTM F1862 Synthetic Blood Penetration Tests. Sanctuary has calibrated test equipment in its lab, and sends masks for independent third party testing.
The SS-KN95 is certified under the GB2626-2019 standard. Most every other KN95 mask on the market is certified under a much less stringent 2006 standard. These masks are currently being used in hospitals, physicians' offices, dental offices and workplaces in a number of industrial settings.
Breatheze SS-KN95 masks are immediately available directly from the company and distributors nationwide.
