New generation N100 safety respirator, ergonomically designed with low profile design to fit under face shields if need be. What we love about this mask is that it offers less breathing resistance, less clogging pressure and inward leakage than other half mask respirators. It also protects users against non-oil based airborne particles, mist and fumes, however it is not suitable for asbestos protection.
