Disposable Respirator, N99, Exhalation Valve, Medium/Large, 10/Box

Description

Dura-Mesh® shell resists collapsing in hot, humid environments. Flame retardants help decrease the flammability of the shell. Softspun lining, a contour molded nose bridge and a soft foam nose cushion make this mask comfortable to wear. Certified to have a filter efficiency of 99% or greater against particulates free of oil. For areas with an oil mist, use an R or P respirator.
