The 3M™ Half Facepiece Respirator Assembly Kit 6291 combines the 3M 6200 Medium half facepiece with two 3M 2091 P100 particulate filters in a single package. The 6200 facepiece is made from thermoplastic elastomer (TPE) and fits medium-sized faces. The 2091 P100 filters provide at least 99.97% filtration efficiency against oil and non-oil-based particles and are compatible with 3M 2000, 5000, 6000, and 7000 Series half facepieces via the bayonet connection. This kit is a convenient starting point for users who need immediate P100 protection for lead, asbestos, silica, metal fumes, or general particulate hazards. The facepiece includes a reclosable storage bag.
What is included in the 6291 kit and do I need to buy anything else to use it?
The 6291 includes the 3M 6200 Medium half facepiece and two 3M 2091 P100 particulate filters. Everything needed for P100 particulate protection is included — no additional purchases are required to start using it. If your application also requires organic vapor or acid gas protection, you would need to swap the 2091 filters for combination cartridges such as the 3M 60921 OV/P100 or 60923 OV/AG/P100, which are sold separately and attach using the same bayonet connection.
What hazards do the 2091 P100 filters in the 6291 protect against?
The 3M 2091 P100 filters provide at least 99.97% filtration efficiency against both oil and non-oil-based airborne particles. They are appropriate for lead dust, asbestos fibers, silica dust, metal fumes from welding or grinding, mold remediation, and other fine particulate hazards. The P100 rating is the highest NIOSH particulate filter class and offers significantly more filtration than N95 or N100.
How do I know if the medium 6200 facepiece in the 6291 fits me?
The 6200 fits most adult faces of medium dimension. A proper fit is confirmed when the facepiece seals against the face without gaps at the cheeks, chin, or nose bridge, and when a negative-pressure user seal check (cover the filters and inhale lightly — the facepiece should collapse slightly and hold) produces no air leakage. Users with larger faces should consider the 6391 Large kit. OSHA 29 CFR 1910.134 requires a formal fit test for workplace use.
Can I reuse the 6200 facepiece from the 6291 with different cartridges?
Yes. The 6200 facepiece uses the standard 3M bayonet connection and is compatible with 3M 2000, 5000, 6000, and 7000 Series filters and cartridges. Once the included 2091 P100 filters are used up or become difficult to breathe through, you can replace them with any compatible 3M cartridge for your specific application — organic vapor, acid gas, combination, or continued P100 particulate protection.
Is the 6291 suitable for lead abatement work?
Yes. The 6200 facepiece paired with 2091 P100 filters provides the P100 particulate protection required for lead abatement under OSHA regulations. For regulated abatement work, a written respiratory protection program including medical evaluation, training, and a formal fit test is required. The 6291 kit is frequently used by renovation contractors and abatement workers for compliance with OSHA lead standards.
How long do the 2091 P100 filters last before they need to be replaced?
Replace the 2091 P100 filters when breathing resistance increases noticeably, when the filters are physically damaged or wet, or at the end of the work shift for heavily contaminated environments. P100 particulate-only filters do not have a chemical service life indicator. For applications with odors or gases, use combination cartridges and replace according to the OSHA change-out schedule for the specific chemical.
