Added carbon layer helps filter out nuisance levels of ozone and organic vapors less than OSHA PEL. For most welding applications. Exhale valve reduces hot air build-up to keep workers cooler. Dura-Mesh shell resists collapsing lasts longer so workers use fewer masks. Flame retardants are added to the shell to help decrease flammability. Contour molded nose bridge with soft foam nose flange provides all-day comfort. Softspun lining increases comfort and durability. NIOSH certified to have a filter efficiency of 95% or greater against particulate aerosols free of oil.
