3M 7800S Series Full Face Respirator 7800S-S 7800S-M 7800S-L

3M 7800S Full Face Respirator — 7800S-S, 7800S-M & 7800S-L

The 3M 7800S Full Face Respirator is 3M's premium silicone full face respirator for demanding industrial work — a rugged, reusable 3M full face mask respirator that delivers APF 50 protection plus integrated eye and face coverage. Built for maintenance departments, contractors, remediation companies, utilities, chemical plants, and municipalities, this 3M bayonet full face respirator twist-locks onto the entire 3M cartridge and filter library and seals reliably across full shifts. Select your size from the three models: the 7800S-S (Small), 7800S-M (Medium), and 7800S-L (Large) using the size selector above.

7800S-S vs 7800S-M vs 7800S-L — How to Size the 3M 7800S

The three 7800S sizes are the same respirator in three facepiece sizes — identical silicone facepiece, APF 50, NIOSH approval, and bayonet cartridges. Only the face seal geometry changes, and a full-face respirator only delivers APF 50 if it seals. Choose your size from the selector above:

Facial dimensions — not height or build — determine fit, and a beard or stubble crossing the seal breaks it regardless of size. OSHA 1910.134(f)(2) requires fit testing before workplace use; if Medium (7800S-M) fails, try Small or Large.

Why Choose a Full Face Respirator? (APF 50)

A full face respirator like the 7800S is required — not optional — when a half mask isn't enough:

• APF 50 vs APF 10: the 7800S provides 5× the protection of a half mask, for environments where contaminant concentrations exceed 10× the Occupational Exposure Limit.
• Eye & face protection: the integrated lens guards against chemical splash, aerosol, and impact — no separate goggles needed.
• Sealing in harsh conditions: the silicone facepiece holds a reliable seal where comfort and durability both matter.

Best Applications for the 3M 7800S

Paired with the right cartridge, the 3M 7800S industrial respirator covers demanding exposures across many industries — match the cartridge to the hazard:

• Chemical handling & splash: the full-face lens protects eyes and skin; pair with an 6003 (organic vapor/acid gas) or 6006 multi-gas cartridge.
• Mold remediation & asbestos removal: 2091 P100 filters for spores and fibers at APF 50.
• Industrial painting & spray: 60921 (organic vapor/P100) for vapor plus paint mist.
• Pesticide spraying: an organic vapor or combination cartridge per the product label.
• Spray foam, epoxy resin & fiberglass: 6001 organic vapor or 60921 where particulate is present.
• Chlorine & acid gas exposure: 6002 acid gas or 60922 (acid gas/P100) — utility and wastewater work.
• Hazardous dust & confined space: P100 filters; full-face seal for confined-space entry teams.

3M 7800S Compatible Cartridges & Filters

The 3M 7800S uses the standard 3M bayonet connection and is compatible with dozens of cartridge and filter options — the same library as the 6000 and 7500 series. Match the cartridge to your hazard:

Review the 3M respirator cartridges and filters guide to select the proper protection for your hazards. For painting, solvents, and chemical processing, the 3M organic vapor cartridge guide explains which cartridge works best with the 7800S platform. Facilities with multiple contaminants often compare the 60921 vs 60923 vs 60926 cartridges before outfitting a full face system. Browse all at 3M Respirator Filters & Cartridges.

OSHA & NIOSH Compliance

• NIOSH approved full-facepiece air-purifying respirator under 42 CFR Part 84 (with approved 3M cartridges).
• APF 50 per OSHA 29 CFR 1910.134 Appendix A — the highest assigned protection factor for an air-purifying respirator.
• Fit testing: OSHA 1910.134(f)(2) requires annual qualitative (QLFT) or quantitative (QNFT) fit testing before operational use and when changing facepiece size.
• Written program: required wherever respirators are used (1910.134(c)), including hazard assessment, medical evaluation (1910.134(e)), and a cartridge change-out schedule (1910.134(d)(3)(iii)).
• Not for IDLH or oxygen-deficient atmospheres — use SCBA or supplied air in IDLH conditions.

Frequently Asked Questions

Is the 3M 7800S NIOSH approved?

Yes — it is a NIOSH-approved full-facepiece air-purifying respirator under 42 CFR Part 84 when used with approved 3M cartridges and filters.

What is the APF of the 3M 7800S?

APF 50 under OSHA 29 CFR 1910.134 Appendix A — five times the protection of a half mask (APF 10), for concentrations up to 50× the Occupational Exposure Limit.

What cartridges fit the 3M 7800S?

All 3M bayonet cartridges and filters — including 6001/6002/6003/6006 cartridges, 60921/60922/60923/60926 combinations, and 2091/2097/2297 P100 filters. Browse the full 3M cartridge & filter lineup.

What is the difference between 7800S-S, 7800S-M, and 7800S-L?

Only facepiece size — Small, Medium, and Large. All three share the same silicone facepiece, APF 50, NIOSH approval, and bayonet cartridges. Most adults fit the Medium; confirm with an OSHA fit test.

How do I choose the correct 7800S size?

Facial dimensions determine fit, not height or build. Most workers start with Medium (7800S-M); if it fails a fit test, try Small or Large. See the per-size reviews: Small, Medium, Large.

Is the 3M 7800S good for asbestos?

Yes — with 2091 P100 filters, the 7800S provides the APF 50 full-face protection used in many asbestos abatement and mold remediation programs. Confirm against your site-specific written program.

Can the 3M 7800S be used with P100 filters?

Yes — it accepts 2091, 2097, and 2297 P100 filters, plus combination cartridges with a P100 built in (60921/60922/60923/60926).

Is the 3M 7800S suitable for painting?

Yes — for industrial painting and spray, use a 60921 (organic vapor/P100) cartridge to handle solvent vapor plus paint mist, with full-face eye protection from overspray.

Can the 7800S be used with 60926 cartridges?

Yes — the 60926 multi-gas/P100 mounts on the 7800S bayonet for broad multi-hazard work with particulate protection.

Is a full face respirator better than a half mask?

For higher concentrations and eye/face hazards, yes — the 7800S gives APF 50 (vs APF 10 for a half mask) plus integrated eye protection. For lower concentrations with no splash hazard, a half mask may be sufficient. Compare in the half face respirator guide.

APF 50 per OSHA 29 CFR 1910.134 Appendix A. No air-purifying respirator is appropriate in IDLH or oxygen-deficient atmospheres — use SCBA or supplied air.
