Verdict: 4.4/5. The 3M 8293 is the max-protection disposable — oil-proof P100 (99.97%) with a face seal and valve, for lead and heavy oil mist. A reusable is cheaper for daily wear.
Verdict: 4.2/5. The 3M 8271 is a simple oil-proof P95 cup with a valve — 95% oil-tolerant filtration without a carbon layer. Right for oil mist; step to P100 for max filtration.
Verdict: 4.0/5. The 3M 8515HA1-A is a flat-fold welding N95 with a valve that fits well under a helmet — good for light fume, but step up to P100 or cartridges for heavy welding.
Verdict: 3.0/5. The 3M 8214 is a niche welding N95 with odor relief that under-delivers for many buyers (2.5★). Right for light, occasional fume only; use P100 or cartridges for real welding.
Verdict: 4.4/5. The 3M 8233 is the maximum non-oil disposable (N100) for lead and heavy fume — right when the hazard demands it, overkill for general dust, and the wrong class when oil is present.
Yes — if your half-mask or full-face respirator is on the MSA Advantage platform and your hazard is radioiodine (elemental iodine I₂ or methyl iodide CH₃I), the MSA 815641 Advantage GMI P100 is your correct cartridge. It delivers the same MERSORB-style charcoal/iodine-specific chemistry as the…

The 815397 20-pack prices out at $3.60 per disc, making it a cost-competitive option for metalworking…
Yes — for general industrial particulate work on a snap-on Advantage platform respirator. The MSA 815369 is a NIOSH-certified P100 filter (≥99.97% efficiency against oil and non-oil aerosols) in a low-profile form factor that improves compatibility with safety glasses. It is the right choice for…
Yes — if your respirator is on the MSA Advantage platform, your hazard is elemental mercury vapor (Hg°) or chlorine (Cl₂), and air monitoring confirms concentrations are below IDLH, the MSA 815368 Advantage MERSORB P100 is your correct cartridge. It applies MSA's proven MERSORB sorbent technology…
Yes — for workers on the MSA Advantage platform who face simultaneous acid gas and fine particulate exposure, the MSA 815363 Advantage GMB-P100 is the right dual-hazard cartridge. It delivers NIOSH-approved acid gas protection against Cl₂, HCl, SO₂, and HF plus P100 particulate filtration (≥99.97%)…
