Product Description Moldex 2400N95 Particulate Respirator with Relief from Nuisance Levels of Organic VaporsNIOSH certified under 42CFR84 regulations to have a filter efficiency level of 95% or greater against particulate aerosols free of oil. Added carbon layer helps filter out ozone and organic vapor odors (less than OSHA PEL). Suitable for most welding fumes (free of oil). Fits easily under welding hoods. Workers stay cooler with an exhale valve that reduces hot air build up. There’s less breathing resistance and workers don’t have to break midshift to cool off. The Dura-Mesh® shell, exclusive to Moldex®, protects the filter media so it stays cleaner-looking longer. The shell resists collapsing, even in heat and humidity so the respirator holds its shape longer. The result is fewer respirators used and lower costs.Perfect for hot, humid and dusty environments such as welding, soldering and brazing, grinding, sanding, sweeping, bagging, stone quarrying, metal machining, cement, underground mining, polishing, buffing, lime, poultry and textiles. No oils present. 100% PVC-Free. Added carbon layer helps filter out nuisance levels of ozone and organic vapors (less than OSHA PEL). Can be used against most welding fumes (free of oil). Dura-Mesh® shell resists collapsing in heat and humidity. Exhale valve lets workers breathe easy and stay cool. Molded nose bridge seals easily without a metal noseband. Facepiece is naturally contoured without pressure points. Straps are securely attached so they don’t break at the seal. Softspun® lining for increased comfort and durability. Soft foam nose cushion for added comfort. Meets heat and flame resistance in accordance with ANSI/ISEA 110.2003 Section 7.11.1.
