Built for comfort and convenience Our 3M™ 7500 Series reusable respirators are made from an advanced silicone material to help give your crew comfort throughout their shifts. The adjustable features are designed to help reduce pressure and tension points on the wearer's face, while the adjustable head cradle provides a secure, personalized fit. When this respirator is not in active use, our drop-down feature allows the respirator to be taken off in a non-contaminated environment without having to remove a hard hat. A versatile choice  The 3M™ 7500 Series is compatible with a wide variety of NIOSH-approved 3M respirator filters and cartridges to help protect your workforce from certain particulates, gases and vapors.  When properly fitted and used with approved 3M cartridges and filters, this respirator may help provide respiratory protection at concentrations up to ten times the OSHA Permissible Exposure Limit (PEL). This half face respirator is also compatible with the 3M™ TR-600 and TR-800 powered air purifying respirators and Dual Airline supplied air systems. Be proactive The 3M Respirator Selection Guide (3M.com/respiratorselector) may be used to help you select the proper respirators, cartridges, and filters for your work environment as well as manage the service life of your products. Change your employee's 3M particulate filters anytime they are dirty, damaged, or difficult to breathe through. For gas/vapor cartridges, use the 3M Service Life software (3M.com/sls) to develop a cartridge change schedule.
