The M95 mask still uses the two core technologies of Green Shield: Kanglun antibacterial technology and Green Shield microfiltration technology, but it is more innovative in product design. Lvdun M95 mask has antibacterial fabric and microfiltration technology. The surface of lvdun M95 mask uses Kanglun antibacterial non-woven fabric with a number of domestic patented technologies, which can effectively inhibit the growth of bacteria on the surface of mask and prevent the threat of secondary pollution; In terms of microfiltration technology, it can effectively filter PM2.5 air particles, and the effect is more than 95%, which can ensure the wearability in the precision working environment. It is widely used in medical and health industry and public places. Whether it is filtration efficiency, air permeability, antibacterial, safety and other aspects are greatly beyond the ordinary mask. And it has anti-virus function.
