Details of the 3M Full-Face Respirator 6900

Respirator Type

The 3M Full-Face Respirator 6900 is a facemask capable of providing top-range respiratory protection.  When used in conjunction with 3M’s P100 filter cartridges, or the 6000 filter cartridges, this respirator is able to provide protection against a wide variety of gases, vapors, and particulate hazards. This full face mask provides protection both to the respiratory system, as well as to the face, increasing the safety of the worker in situations where damage to the eyes or soft-tissue on the face may occur.



The 3M Full-Face Respirator 6900 offers more protection than most respirators because of its full-face shield. Most respirators come in a half-face form leaving the eyes exposed and often requiring the wearer to use safety glasses. The 3M Full-Face Respirator 6900 facepiece is made of a silicone and thermoplastic elastomer (TPE). The silicone face seal allows the face shield to fit comfortably on the face and create an airtight seal which is crucial to the safe operation of a full-face respirator.

The lens of the 3M Full-Face Respirator 6900 is hard-coated polycarbonate. It comes installed with bayonet attachment inhalation port fittings, inhalation valves, and inhalation port filter/cartridge gaskets. While the face shield has an external hard coating, it can be susceptible to scratches if used in an environment where there might be contents hitting the face shield. Replacement face-shields are about USD$25. However, a more viable option is, similar to what you would do with a phone screen, use a face-shield protector, which can be purchased for quite cheap and does not impair or alter the vision of the respirator, but does protect it from scratches.3M Full-Face Respirator 6900 mask


The silicone-based nosecup of the 3M Full-Face Respirator 6900 holds the inhalation valves of the respirator system. It is installed in the system in a manner where it can be easily removed for washing, or replaced should it be damaged. It is installed over the center adapter of the mask and fits easily over any wearer’s mouth and nose. Because of its loose design and silicone base, the nosecup very easily vents exhaled air out of the system to prevent the lens from fogging.

Head Harness

The 3M Full-Face Respirator 6900 uses elastomer rubber straps for its head harness system. These are attached to the back in a single molded unit as seen in the image below. The straps are fastened to the facepiece system using the retraction clip buckles. The pull points on the harness are located closer to the face of the mask to act tighteners when pulled together.

Front Module


The 3M Full-Face Respirator 6900’s front module consists of the hard-coated polycarbonate face shield coating which is built around the center adapter assembly. The front of the gas mask, where the 3M label is located, is the protective cover for the assembly system which includes the exhalation valve, center adapter base, and center adapter gasket. The center adapter and port adaptor are the intricate parts of this respirator and therefore front on impacts should be avoided with this respiratory system.

3M Full-Face Respirator 6900’s exhalation system is based through the respirator’s downward pointing exhalation valve, which stems from the center adapter assembly. This means that when the wearer is exhaling through the mask, the exhaled air runs in a downward motion to avoid air being pushed forward onto working areas.3M Full-Face Respirator 6900 front module
