SAS Safety 8621 R95 Valved Particulate Respirator — 10-Pack — NIOSH-Approved R95 Disposable Respirator
An air-purifying respirator filters air, it does not supply any. Under 29 CFR 1910.134 no air-purifying respirator may be worn in an atmosphere that is IDLH or oxygen-deficient (below 19.5% oxygen). Those conditions require a supplied-air respirator or an SCBA, and no filter or cartridge rating changes that.
SAS Safety 8621 R95 Valved Particulate Respirator — 10-Pack adds an exhalation valve to SAS Safety's R95 cup respirator — the valve vents warm exhaled air out of the mask during spray painting and oil-mist operations, making extended shifts in oil-based environments measurably cooler than the unvalved 8620.

Hazard Coverage — SAS Safety 8621 R95 Valved Particulate Respirator — 10-Pack
The SAS Safety 8621 R95 Valved Particulate Respirator — 10-Pack is NIOSH-approved under 42 CFR 84 Subpart K as an R95 respirator: ≥95% filtration, rated for both non-oil and oil-resistant particulates for up to one work shift of oil aerosol exposure. Covered environments: spray painting, automotive body work, machining with cutting fluids, oil-mist coolants. Browse all R95 respirators.
The R95 is oil-resistant not oil-proof — after one shift of continuous oil exposure, discard the 8621. Step up to a P100 for heavy or extended oil mist. See our N95 vs P100 guide.

Frequently Asked Questions
What does the exhalation valve on the 8621 do?
The exhalation valve opens when you breathe out, allowing warm humid air to exit directly rather than passing back through the filter media. This reduces heat and moisture buildup inside the mask — a significant comfort advantage during extended or physically demanding wear. Inhalation closes the valve, so all inhaled air is filtered normally.
Does the valve on the 8621 reduce filtration efficiency?
No. The exhalation valve does not affect inhalation filtration efficiency — the 8621 still filters inhaled air at the rated N95/R95/P100 level. The valve only controls exhaled air routing. Note: because exhaled air is not filtered, valved respirators are not appropriate as source-control devices (e.g., in surgical environments or when protecting others from the wearer).
Is a valved respirator like the 8621 acceptable for source control?
No. A valved respirator directs exhaled air outward unfiltered and is not appropriate where the wearer must also protect others (surgical settings, some healthcare environments). Facility policies may prohibit valved masks in sterile or at-risk patient areas. For source-control requirements, use an unvalved N95 or a surgical N95.
Is the 8621 NIOSH-approved for oil mist?
Yes. The 8621 holds NIOSH R95 approval under 42 CFR 84 Subpart K, confirming ≥95% filtration of both non-oil and oil-resistant particulates. The R in R95 means the mask is approved for oil-based aerosols for up to one work shift (8 hours of continuous oil aerosol exposure). Compare classes in our N95 vs P100 guide .
What is the difference between R95 and N95 for the 8621?
The 8621 is rated R95 — oil- resistant (one shift) — while N95 masks are rated for non-oil environments only. If you spray paint, work with cutting fluids, or handle oil mist, the R95 class is the correct minimum; for extended or heavy oil exposure, step up to a P100 (oil-proof, no time limit). Browse all R95 respirators .
Can the 8621 be used for spray painting?
Yes, the 8621's R95 rating covers oil-based aerosols including spray paint and primer mist for up to one shift. OSHA recommends pairing it with forced-air ventilation in enclosed spray environments. For longer exposures or lacquers with solvent vapors, also consider an OV cartridge — the R95 particle filter alone does not capture organic vapors.
Does the 8621 require a fit test?
Yes. OSHA 29 CFR 1910.134 mandates a fit test before first workplace use of any tight-fitting respirator. See our fit testing guide for the qualitative and quantitative options. Proper seal at the nose bridge and chin is required for rated R95 performance.
How long can I use the 8621 in an oil mist environment?
The R95 class is approved for up to one work shift of oil aerosol exposure; after that, oil can degrade the electret filter media and reduce efficiency below 95%. Discard the 8621 at end of shift if used in oil-mist conditions, or sooner if breathing resistance increases noticeably.
What does the 8621 NOT protect against?
The 8621 protects against oil and non-oil particulates only — it does not filter gases, vapors, or chemical vapors such as organic solvents or acid gases. Nuisance-relief versions add a thin sorbent layer for comfort only, not IDLH chemical protection. For vapor hazards, use a half-face or full-face respirator with an OV or AG cartridge.
Can I use the 8621 for welding?
Welding fume is classified as a particulate hazard. An R95 like the 8621 provides adequate particle protection for mild steel MIG/TIG welding. For stainless steel, galvanized metal, or chromate primer grinding — which generate hexavalent chromium — a P100 provides higher protection. Check your welding fume exposure assessment or SDS.
How many 8621 respirators come in a box?
Pack size is shown in the product title. For bulk orders, contact our B2B team for volume pricing. Browse all R95 respirators for available pack formats.
Is the 8621 reusable?
No, the 8621 is a disposable respirator. Discard it when soiled, damaged, breathing becomes difficult, or at end of shift in oil-mist environments. Attempting to clean or wash a disposable N95/R95 can damage the electret filter and reduce filtration efficiency without providing any visible indication.
