The KN95 face respirator is designed to limit unfiltered air entry with the flaps staying flushed against your face. This provides a secure seal and double protection from all sides of the face respirator. The 2 layers of inner melt-blown filter fabric increases the filtration efficiency for double protection against the virus. Its innovative 3D design allows for more space between your mouth and the face respirator and reduces the risk of the wearer readjusting it. Made with premium melt-blown filter fabric with BFE (Bacterial Filtration Efficiency) ≥98% and PFE (Particle Filtration Efficiency) ≥98%, the product is able to block out pollution, pollen and dust particles from our surroundings. Suitable for daily use.
