Moldex® N95 Medium. Large Particulate Disposable Respirator. Procedure Mask has a molded nose bridge with soft foam nose cushion for an easy and comfortable fit. Mask is 100% PVC free that meets heat and flame resistance in accordance with ANSI / ISEA 110-2003 Section 7.11.1 and NIOSH 42CFR84 standard. The Dura-Mesh® shell protects the filter media that resists collapsing in regular use and even under hot and humid conditions, so the respirator holds its shape longer. Mask features contour molded nose bridge seals without a metal noseband and Softspun® inner lining that adds comfort and durability. The result of using the mask is fewer respirators used and lowers costs. Mask has no metal noseband to adjust and the seal is maintained without pressure points. Mask includes straps which are securely attached so they don't break at the seal and face piece is naturally contoured without pressure points. Mask is applicable in 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. Mask is sold as 20 per box. Do not use against concentrations of contaminants which are unknown or are immediately dangerous to life or health concentrations of particulates which exceed the maximum use concentration of 10 times the OSHA permissible exposure limit, whichever is lower.
