The innovative design of 3M™ Respirators 5000 Series makes them an easy, economical way to help ensure worker protection. They are pre-assembled, have no spare parts and require little or no maintenance. Their lightweight, well-balanced design helps provide greater worker comfort. Low profile design allows for a wider field of vision and greater comfort while wearing glasses or goggles. A resalable storage bag helps keep respirator clean between uses. The 5000 series respirators are available in three sizes to fit a wide variety of facial sizes. All respirators/filter assemblies can be used up to the NIOSH approval limits, 10 times the permissible exposure limit, or the maximum use concentration allowable in applicable OSHA standards, whichever is lower.
