Is the 3M 8293 the best disposable P100 respirator?

Short answer: It is the top of the disposable tree. The 3M 8293 is an oil-proof P100 filtering facepiece — 99.97% filtration that tolerates oil — with a face seal and a Cool Flow valve. It is the disposable to reach for when both maximum filtration and oil resistance matter, such as lead or oil mist. Beyond it, you move to reusable elastomerics.

3M 8293 P100 Disposable Respirator Review (2026)

The 3M 8293 is 3M's highest-rated disposable: P100, oil-proof, valved, with an added face seal. This spec-based review covers where it fits the P100 disposable respirators range and when a reusable makes more sense. Ratings background is in our complete disposable respirator & N95 mask guide.

Editorial verdict — 4.4/5
The 3M 8293 is the maximum-protection disposable: 99.97% oil-proof P100 filtration with a face seal and Cool Flow valve for comfort. It is the right disposable for lead, heavy oil mist, and high-hazard particulate. The only step up is a reusable elastomeric with P100 cartridges — often cheaper for daily wear.VIEW ON WC SAFETY →CHECK PRICE ON AMAZON →

Who it is for

• Workers on lead, heavy oil mist, or high-hazard particulate needing max filtration
• Buyers who want P100 in a grab-and-go disposable
• Teams weighing disposable P100 vs a reusable half mask

What the 3M 8293 does well

Maximum oil-proof filtration

P100 means 99.97% efficiency and oil-proof — the highest a disposable offers, covering oil mist and the worst particulate. See N95 vs P100.

Face seal and valve

The added face seal improves the fit margin and the Cool Flow valve keeps the dense P100 filter breathable.

The disposable ceiling

For high hazards where you still want a disposable, the 8293 is as far as filtering facepieces go before reusables. See respirator filter types explained.

Where the 3M 8293 falls short

Most expensive disposable

P100 disposables cost the most per mask; for daily high-hazard wear a reusable half mask with P100 filters is often cheaper over time.

Bulk and resistance

A P100 filter is denser and bulkier than an N95, even with the valve.

Valved, single-use

No source-control use; it is a consumable.

When to step up from the 3M 8293

Wearing P100 daily? A reusable half mask with P100 filters is usually cheaper per day and reusable. If 95% is enough, the 3M 8271 P95 saves money; for non-oil only, the 3M 8233 N100. Ranked picks in our best N95 respirators guide.

Category context

The 8293 is the high end of disposable respirators — maximum filtration with oil resistance. Where disposables give way to reusables is covered in our disposable respirator guide and N95 vs KN95 vs P100.

Total cost of ownership

As the priciest disposable, the 8293 makes sense for intermittent high-hazard work; for daily P100 wear, cost out a reusable half mask with P100 filters. Replace when soiled, damaged, or hard to breathe through (see can you reuse an N95?).

Final verdict

The 3M 8293 earns 4.4/5 — the maximum-protection disposable. Buy it for lead, heavy oil mist, or high-hazard particulate in a disposable; for daily wear, a reusable half mask with P100 filters is usually the smarter spend.

3M 8293 FAQ

Is the 3M 8293 a P100 respirator?

Yes — it is an oil-proof P100 filtering facepiece, 99.97% minimum filtration, the highest class in a disposable. It is NIOSH-approved under 42 CFR Part 84.

3M 8293 vs 3M 8233 — what is the difference?

Both filter 99.97%; the 8293 is P100 (oil-proof) while the 3M 8233 is N100 (non-oil). Choose the 8293 when oil is present, the 8233 for non-oil hazards at lower cost.

3M 8293 vs a reusable P100 half mask — which is better?

For intermittent use, the disposable 8293 is convenient; for daily wear a reusable half mask with P100 filters is usually cheaper per day and reusable. Choose by frequency of use.

Is the 3M 8293 good for lead?

Yes — P100 is a strong choice for lead and other high-hazard particulate, paired with controls and a written program.

Does the 3M 8293 protect against oil mist?

Yes — P100 is oil-proof, so it handles oil aerosols as well as solid particulate, unlike an N-series mask.

Does the 3M 8293 have a face seal?

Yes — an added face seal improves the fit margin, and a Cool Flow valve keeps the dense filter breathable.

Can you reuse a 3M 8293?

Single-use with limited reuse when constrained; discard when soiled, damaged, or hard to breathe through. See can you reuse an N95?.

Does the 3M 8293 require fit testing?

Yes for OSHA-regulated use — medical evaluation, annual fit test, and seal check per OSHA 29 CFR 1910.134.

Can I wear the 3M 8293 with a beard?

No — facial hair across the seal fails the fit test; clean-shaven along the seal is required, or use a PAPR.

Does the 3M 8293 protect against gases?

No — it is a particulate respirator. Gases and vapors need a half mask with the correct cartridge.

Is the 3M 8293 worth the higher price?

For high-hazard intermittent work where you want a disposable, yes. For routine dust an N95 is fine; for daily P100 wear a reusable is usually cheaper.

3M 8293 vs 3M 8271 — which oil-proof to buy?

The 8293 is P100 (99.97%), the 8271 is P95 (95%). Choose the 8293 for maximum filtration, the 8271 to save money when 95% is enough.

How long does a 3M 8293 last?

No fixed hours — replace at end of task or when dirty, damaged, or breathing resistance rises.

Is the 3M 8293 a surgical respirator?

No — it is industrial without FDA clearance. See surgical N95 respirators.

What is the highest-protection disposable respirator?

An oil-proof P100 like the 3M 8293 — 99.97% filtration with oil resistance. Beyond it you move to reusable elastomeric respirators.
