Moldex 2300N95 Disposable Particulate Respirator with Exhale Valve, Medium/Large, NIOSH Approved - 20 Per Box 

• LASTS LONGER LESS WASTE Exclusive DURA-MESH SHELL protects the filter media, so it stays cleaner-looking longer. The shell also resists collapsing in hot, humid environments, so the respirator holds its shape longer and the result is fewer respirators used and lower costs.
• EXHALE VALVE lets workers breath easier and stay cooler.
• MORE COMFORT LESS PRESSURE the face piece is naturally contoured and the molded pinch free nose bridge seals easily without a metal nose band.
• GET COMFORTABLE with softspun lining and soft foam nose cushion.
• SUSTAINABLE SOLUTIONS 100% PVC-Free, like all Moldex products and packaging.
• Warnings: Always refer to warnings and instructions prior to use.
