NIOSH Items: We only sell brand new respirators, filters, and dust masks from US based manufacturers. Since it can be difficult to determine if a respirator or mask has been used or even just tried on, for the protection of our customers, we do not accept NIOSH returns.
2400 N95 Particulate Respirator, Plus Nuisance Levels of Ozone and Organic Vapors. Added charcoal sorbent layer helps filter out nuisance levels of ozone and organic vapors (less than OSHA PEL). Useful for most welding applications that do not involve lead or cadmium. The exhale valve reduces hot air build-up to keep workers cooler, while also helping to reduce fogging of your safety glasses. The Dura-Mesh shell resists collapsing lasts longer so workers use fewer masks, while the Softspun lining increases comfort and durability. Flame retardants are added to the shell to help decrease flammability, which is especially useful in welding applications. The contour molded nose bridge with soft foam nose flange provides all-day comfort and extra sealing efficiency. NIOSH certified to have a filter efficiency of 95% or greater against particulate aerosols free of oil. Packaged and sold in a bag of 10 masks.
