Our 5-layered KN 95 FFP2 mask is crafted with precision, its non-woven outer and inner layers ensure a comfortable airflow. This mask features a double melt-blown filter which not only makes it KN95 compliant but also offers double protection against viruses and infectious diseases. The hot wind filter effectively captures PM 2.5 particles, the major culprit behind respiratory diseases, ideally suited for dusty & polluted environments.
