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.\u003c\/p\u003e\n\n\u003ch2\u003eConstruction and Filter Media\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch2\u003eNIOSH Approval and Compliance\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch2\u003ePerformance in Industrial Environments\u003c\/h2\u003e\n\u003cp\u003eThe R95 filter performs effectively in general industrial particulate environments including woodworking dust, nuisance dusts, some metal dusts, and aerosol environments where 95% efficiency is sufficient for the applicable OEL. In oily environments, the filter should be replaced at the end of each shift per NIOSH R-series guidance, rather than solely on the basis of breathing resistance. Box of 20 provides a cost-effective supply for high-filter-turnover operations where per-filter cost is a meaningful procurement consideration.\u003c\/p\u003e\n\n\u003ch2\u003eStrengths\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOil-resistant rating maintains 95% efficiency in machining, metalworking, and other oil mist environments where N-series filters would degrade\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/blogs\/guides\/n95-vs-kn95-vs-p100-which-respirator-do-you-actually-need\" style=\"color:#4fc3f7;\"\u003eBox of 20 provides lower per-filter cost than P100 options — practical for high-turnover operations\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/blogs\/guides\/n95-vs-kn95-vs-p100-which-respirator-do-you-actually-need\" style=\"color:#4fc3f7;\"\u003e95% efficiency is adequate for many general industrial particulate applications where OELs do not require P100\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eCompatible with all MSA Comfo half-mask respirators via the standard bayonet mount\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eLimitations\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/blogs\/guides\/n95-vs-kn95-vs-p100-which-respirator-do-you-actually-need\" style=\"color:#4fc3f7;\"\u003e95% efficiency is lower than P100 (99.97%) — for silica, lead, beryllium, hexavalent chromium, or substances with very low OELs, P100 is the appropriate selection\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eR-series filters are limited to single-shift use in oily environments per NIOSH guidance — not suitable for extended reuse in oil mist applications\u003c\/li\u003e\n\u003cli\u003eNo chemical vapor protection — combination cartridges are required for environments with concurrent chemical hazards\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eRecommended Use Cases\u003c\/h2\u003e\n\u003cp\u003eThe R95 is suited for general woodworking and carpentry dust, metalworking operations with oil mist where 95% efficiency meets the applicable OEL, agricultural dusts, nuisance particulate environments, and applications where the cost savings of R95 over P100 are meaningful for high-volume filter use.
