The Moldex 2300 N95 Particulate Respirators is designed to be long lasting and comfortable to wear. This respirator has an exhale valve to reduce hot air build up and keep workers cooler. Workers will need fewer breaks to cool off. The Dura-Mesh shell keeps the filter cleaner longer and protects its shape. The Dura-Mesh shell doesn’t collapse even in hot and humid environments. The Softspun lining cushions the face without pressure points. The 2300 has the N95 filter which is ideal for high dust environments without oils present.
