The first and only NIOSH N95-approved single adjustable cotton strap respirator gives you a quick fit. This latex-free respirator is both a N95 respirator and surgical mask. The non-latex straps don't irritate, don't require pre-stretching and they are securely attached. The exclusive Dura-Mesh® shell 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. The molded nose bridge with foam face cushion fits easily and comfortably without a metal nose band. Meets CDC guidelines for protection against TB and has the highest ASTM level of fluid resistance on the market (160mm Hg) with a bacterial filter efficiency >99.9%. NIOSH certified to have a filter efficiency level of 95% or greater against non-oil based particulates. Straps come in 3 color coded sizes. This product meets heat and flame resistance in accordance with ANSI/ISEA 110-2003 Section 7.11.1. (100% PVC-Free)
