3M 60928 Review: OV/Acid Gas/P100 Cartridge & Methyl Bromide
Editorial Verdict — 3M 60928: 4.6/5
"The 3M 60928 is an organic vapor / acid gas / P100 combination cartridge that does one extra thing its near-twin the 60923 does not: it carries 3M's special-use recommendation for methyl bromide and radioiodine. For most mixed-chemical work the two are interchangeable, but if your program covers fumigation or radioactive iodine, the 60928 is the cartridge written into it."
We rate the 3M 60928 4.6/5 for combined organic vapor, acid gas, and particulate work — with niche value for fumigation and nuclear settings. Its closest alternative is the 60923 for ordinary OV/acid gas/P100 use; the gas-only sibling is the 6003.

Quick Verdict
The 3M 60928 is a combination cartridge with a specialty role: it provides organic vapor, acid gas, and P100 particulate protection in one bayonet body, and it carries 3M's additional recommendation for methyl bromide and radioiodine. It is the right cartridge for chemical work with mixed gas and particle hazards — and specifically for fumigation crews and nuclear-industry programs that need a designated methyl bromide or radioiodine cartridge.
It is the wrong cartridge when there is no particulate (the gas-only 6003 is lighter and cheaper), when there is no acid gas (the 60921 OV/P100 is enough), or when ammonia is present (the multi-gas 60926 is the match — the 60928 does not cover ammonia).
For ordinary organic vapor / acid gas / particulate work, the 60928's closest alternative is the standard 60923; the two share the same core NIOSH approval.

What the 3M 60928 Is Designed For
The 60928 is a triple-stage combination cartridge in the 3M 60900 series: an organic-vapor sorbent, an acid-gas sorbent, and a P100 particulate filter in one bayonet body. NIOSH approves it for organic vapor, chlorine, hydrogen chloride, sulfur dioxide, hydrogen sulfide, hydrogen fluoride, and formaldehyde, plus 99.97% P100 particulate. The P100 stage is oil-proof, so it holds efficiency in acid-mist and solvent-aerosol environments.
What sets it apart from the otherwise-similar 60923 is its special-use designation: 3M's technical guidance recommends the 60928 for methyl bromide (at ambient concentrations up to 5 ppm, for no more than one shift) and for radioiodine (radioactive iodine). That is why it shows up in agricultural and structural fumigation programs and in nuclear-industry respiratory protection. In the lineup it is a combination-tier cartridge with a fumigation/nuclear specialty. For the acid-gas side, see the acid gas respirator cartridge guide; for the particulate concept, see organic vapor vs P100.
Key Specifications
| Specification | 3M 60928 |
|---|---|
| Protection type | Organic vapor + acid gas (Cl2, HCl, SO2, H2S, HF) + formaldehyde + P100 |
| Special-use (per 3M) | Methyl bromide (≤5 ppm, ≤1 shift) and radioiodine |
| Filter rating | P100 (99.97%, oil-proof) — integrated |
| Color code | Yellow (OV/AG) with magenta P100 band — see the cartridge color code chart |
| Compatible respirator series | 3M 6000 / 6500QL / 7500 half masks; 6000 & 7800S full face (bayonet) |
| Better alternative when | Ordinary OV/AG/particulate → 60923; no particulate → 6003; no acid gas → 60921; ammonia present → 60926 |
Real-World Use Cases
Chemical handling & manufacturing. Mixed solvent and acid-gas streams with process dust — covered in one cartridge, like the 60923.
Maintenance — fumigation. Structural and agricultural fumigation crews who need a designated methyl bromide cartridge use the 60928 within its 5 ppm / one-shift limit, alongside monitoring and supplied air where concentrations are higher.
Chemical handling — nuclear / radioiodine. Nuclear-industry respiratory programs specify the 60928 for radioactive iodine exposure as part of a broader controls and monitoring program.
Painting. Spray application of acid-catalyzed coatings, where solvent vapor and an acid component meet atomized paint mist — the P100 stage handles the mist.
Note: for ordinary single-solvent painting with no acid gas, the lighter 60921 is the better fit — the 60928's acid-gas stage and specialty scope are unnecessary there.
What This Cartridge Does Well
- Covers organic vapor, acid gas, and particulate in one cartridge — the common mixed industrial profile
- Carries 3M's special-use recommendation for methyl bromide and radioiodine, which standard combination cartridges do not
- Oil-proof P100 stage holds efficiency in acid-mist and solvent-aerosol environments
- Uses the standard 3M bayonet connection, fitting the entire 3M half-mask and full-face bayonet range
- Lets fumigation and nuclear programs standardize on a designated, NIOSH-approved cartridge
Where This Cartridge Is Not the Right Choice
The 60928 is broad but bounded, and for everyday work a simpler cartridge often fits better:
- Ordinary OV/acid gas/particulate with no fumigation or radioiodine need — the standard 60923 does the same core job.
- No particulate present — the gas-only 6003 covers the same gases at lower cost and breathing resistance.
- No acid gas present — the 60921 (OV/P100) is lighter for solvent-plus-particulate work.
- Ammonia present — outside the 60928's approval; use the multi-gas 60926. Methyl bromide above 5 ppm or any IDLH condition requires supplied air, not this cartridge.
3M 60928 vs Similar 3M Cartridges
| Cartridge | Protects against | P100 filter | Best when |
|---|---|---|---|
| 60928 (this review) | OV + acid gas (+ methyl bromide / radioiodine special use) | Yes | Mixed chemical + fumigation / radioiodine |
| 60923 | Organic vapor + acid gas | Yes | Ordinary OV/acid gas + particulate |
| 6003 | Organic vapor + acid gas | No | Same gases, no particulate |
| 60921 | Organic vapor | Yes | Solvent + particulate, no acid gas |
| 60926 | Multi-gas (adds ammonia) | Yes | Mixed gases incl. ammonia + particulate |
The decision is mostly about the specialty: if you do not need methyl bromide or radioiodine coverage, the 3M 60923 review describes the equivalent everyday cartridge; if you need ammonia too, read the 3M 60926 review and the 3M 60923 vs 60926 comparison. For the OV-only combination, see the 3M 60921 review.
Compatible Respirators
The 60928 uses the 3M bayonet connection and fits the full 3M bayonet respirator range — half mask and full face:
- 3M 6000 Series half masks — the 6100/6200/6300
- 3M 6500QL Series half masks — the 6501/6502/6503 Rugged Comfort respirators
- 3M 7500 Series half masks — the 7500 Series silicone half masks
- 3M 6000 Series full face — the 6000 full facepieces (APF 50)
- 3M 7800S Series full face — the 7800S full facepieces
- 3M Ultimate FX FF-400 full face — the Ultimate FX FF-400 respirators
3M bayonet cartridges do not fit Honeywell North, MSA, or Moldex masks, and the 60928 is not a Secure Click cartridge — confirm the mount in our respirator cartridge compatibility guide.
Who Should Buy This Cartridge?
- Fumigation crews who need a designated methyl bromide cartridge within 3M's concentration and duration limits
- Nuclear-industry and lab teams with radioiodine exposure in their respiratory protection program
- Chemical process and maintenance workers facing organic vapor, acid gas, and particulate together
- Not the right choice for everyday OV/acid gas work with no specialty need (use 60923), gas-only air (use 6003), no acid gas (use 60921), or ammonia environments (use 60926)
Final Recommendation
Buy the 3M 60928 when your program specifically calls for methyl bromide or radioiodine coverage, or when you want a single OV/acid gas/P100 cartridge that also carries those designations. For ordinary mixed-chemical work without that need, the 60923 is the equivalent and more common choice; drop to the gas-only 6003 with no particulate, the 60921 with no acid gas, or up to the 60926 for ammonia. Confirm the match with the 3M respirator cartridge guide, build the change interval from the respirator cartridge lifespan guide, and shop the 3M respirator cartridges and filters collection.
