The MSA R95 Particulate Filter for Comfo Respirators — Box of 20 is a respirator filter from MSA Safety, stocked at $100.70. This review restates what the product page documents, places it in its respiratory protection lane, and points to the ranked guides for the head-to-head field.
What the Product Page Documents
The MSA R95 Particulate Filter (SKU 816287) provides NIOSH R95-rated protection — 95% minimum filtration efficiency with oil-resistance — for the MSA Comfo half-mask respirator platform. The R95 designation distinguishes it from N-series filters (not oil-resistant) by maintaining rated efficiency in oil-mist environments. Sold in a box of 20, the R95 filter offers a cost-effective particulate protection option for Comfo users whose applications do not require the higher 99.97% efficiency of P100 filtration. Compatible with the Advantage 200 LS, Comfo Classic, and Comfo II half-mask respirators.
The R95 filter uses electrostatic filter media rated to at least 95% efficiency against the most penetrating particle size. The "R" designation indicates oil-resistant — the filter has been tested for performance in oil-based aerosol environments and maintains rated 95% efficiency in those conditions. Unlike P100 filters (oil-proof), R-series filters have a time limitation in oily environments per NIOSH guidance: typically a single shift or 8 hours of use in oil-containing aerosols before replacement. The filter attaches to the Comfo facepiece via the bayonet mount in the same manner as chemical cartridges and combination cartridges.
The R95 is NIOSH-approved under 42 CFR Part 84 for R95 particulate service: at least 95% efficiency, oil-resistant. When used with a properly fitted MSA Comfo half-mask, the system delivers an APF of 10 per OSHA 29 CFR 1910.134. For environments with the highest-hazard particulates — silica, lead, beryllium, hexavalent chromium, asbestos — P100 (99.97%) filtration is the appropriate standard. The R95 is appropriate where the applicable OEL can be met with 95% filtration efficiency at the concentrations present in the work environment.

Frequently Asked Questions
How much does the MSA R95 Particulate Filter for Comfo Respirators — Box of 20 cost?

What does the MSA R95 Particulate Filter for Comfo Respirators — Box of 20 listing actually document?
The MSA R95 Particulate Filter (SKU 816287) provides NIOSH R95-rated protection — 95% minimum filtration efficiency with oil-resistance — for the MSA Comfo half-mask respirator platform.

What are the alternatives to the MSA R95 Particulate Filter for Comfo Respirators — Box of 20?
The sibling respirator filter options linked in this review, ranked head-to-head in the respiratory protection guides below — start with the buyer's guides for the field view.
What do N95, P100, and the letter/number classes mean?
The letter is oil resistance (N=not, R=resistant, P=oil-proof); the number is filtration efficiency (95/99/100 ≈ 95%/99%/99.97%). The class on the listing is the class — higher isn't always better if breathing resistance parks the mask on the chin.
When does OSHA require fit testing for this equipment?
Any employer-required tight-fitting respirator — N95s included — needs fit testing before use and annually per 1910.134, plus user seal checks every wearing. Loose-fitting PAPRs are the exception.
How long do cartridges and filters last?
Chemical cartridges follow a change schedule (or end-of-service indicators) — odor breakthrough is a failure, not a signal. Particulate filters last until breathing resistance rises or damage/loading shows. The employer's change schedule is a 1910.134 requirement.
Can I pair any cartridge with any facepiece?
No — attachment systems are proprietary (bayonet counts and geometries differ by brand and series). Reviews here restate the compatibility each listing claims; the manufacturer's matrix governs.
What does a respirator NOT protect against?
Air-purifying respirators don't supply oxygen — oxygen-deficient atmospheres and IDLH conditions require supplied air. And a cartridge only stops what its class covers; the SDS names the contaminant to match.
Why does facial hair matter?
Anything between skin and seal defeats tight-fitting respirators — it fails fit tests and the standard. The options are shaving policy or loose-fitting PAPRs; there is no third answer.
How should respirators be cleaned and stored?
Per 1910.134 Appendix B-2: cleaned and sanitized (alcohol-free wipes between uses, periodic washing), stored away from contamination, sunlight, and distortion. Filters stay sealed until service.
What's the difference between a half mask and full face for the same cartridge?
Assigned protection factor (10 vs 50 for full face) and eye protection — the same cartridge protects longer lungs-wise on a full face because leakage is lower. Exposure levels pick the facepiece.
Are exhalation valves allowed?
For most industrial use, yes — valves ease breathing without lowering protection for the wearer. Sterile fields and source-control settings restrict them; that's a policy question, not a NIOSH one.
What is an assigned protection factor (APF)?
The exposure multiplier a respirator class is credited with under 1910.134 — half masks 10, full face 50, PAPR hoods 25-1000 by type. Exposure over PEL×APF means stepping up the class.
PAPR vs negative-pressure — when to step up?
Comfort over long shifts, beards, high exposures, and heat all point to PAPRs — blown air instead of pulled. The cost gap narrows once cartridge consumption and compliance are priced in.
Do respirators expire?
Filters and cartridges carry shelf lives sealed; facepiece elastomers age with use and cleaning chemistry. Date-check stock, rotate it, and let the fit test catch what inspection misses.
The Bottom Line
Rated 4.6/5 on documented spec, configuration, and value. The MSA R95 Particulate Filter for Comfo Respirators — Box of 20 does the job its listing describes — the guides above tell you whether it's the right pick against the field.
