With many municipalities still requiring the use of face masks, these 3-layer masks are decently affordable and ready to ship in the US. This ships direct from Amazon. I know these are not N95 masks and won’t fully protect you from the virus but if enough of us are wearing these when it’s necessary for us to be in public, it can slow down the rate of infection. The KN95 mask is made of 2 non-woven outer layers, 2 melt-blown inner filter, 1 non-woven cotton middle layer, and offers more protection than a standard disposable 3-Ply mask. The filtering efficiency is 95%, greatly keeping you from dust, PM 2.5, haze, smoke, automobile exhaust, etc. Everyone, please be stay safe!
