3M Secure Click D3078 Review: P95 Particulate Filter
Editorial Verdict — 3M Secure Click D3078: 4.5/5
"The D3078 is the single-pair version of the same P95 particulate filter as the D3071 — 95% efficient, oil-resistant, particulate only. The smaller pack suits kit builds, trials, and low-volume use; for standard stocking the D3071 is usually more economical. Step up to the D9093 P100 when you need the highest efficiency."
The 3M Secure Click D3078 is a P95 particulate filter for the 3M Secure Click HF-800 and FF-800 platform, sold as a single pair. It is the same protection class as the D3071 — at least 95% efficient against all particulate, and oil-resistant because it is P95 — packaged in a smaller, single-pair format. It provides primary particulate protection on its own; it is a particulate filter only, with no gas or vapor protection, so pair the platform with a gas/vapor cartridge when gases are present. The single-pair pack suits kit builds, fit-test and trial use, occasional users, and low-volume programs; for standard, high-volume stocking the D3071 is usually the more economical way to buy the same P95 protection. When the highest particulate efficiency is required, step up to the D9093 P100. As always, the filter must match the contaminant and exposure in your hazard assessment.
Quick Verdict
- Best for: Single-pair P95 particulate protection — kit builds, trials, occasional and low-volume use
- Not ideal for: Gas/vapor hazards, high-volume stocking, or tasks requiring P100 99.97% efficiency
- Protection type: P95 particulate filter (95%, oil-resistant) — not P100
- Compatible platform: 3M Secure Click HF-800 and FF-800 Series
- Requires retainer? No — it is a complete filter that seats on the facepiece
- P100 included? No — P95 class; step up to the D9093 for P100
- Better alternative when needed: D3071 (same P95, standard pack) or D9093 (P100 step-up)
What Is the 3M Secure Click D3078?
The 3M Secure Click D3078 is a P95 particulate filter sold as a single pair — a complete filter that seats on the Secure Click facepiece and provides primary particulate protection, not a thin prefilter pad. The P95 rating means it captures at least 95% of all particulate and is oil-resistant. Functionally it is the D3071 in a smaller pack: the protection is identical, the packaging differs. It belongs to the 3M Secure Click cartridge and filter guide family and attaches with the platform's push-and-click latch. To sort out which element does what, see how to choose a respirator cartridge and P95 vs P100 filters.
What Does the 3M Secure Click D3078 Protect Against?
The D3078's role is standalone particulate protection:
- All particulate at 95% (P95) — dusts, mists, and fumes, including oil-based aerosols.
- Oil resistance — usable around oil mists, unlike N95 media.
- No gas/vapor protection — for gases, use a gas/vapor cartridge such as a D8001 or D8006 instead.
- Step-up available — the D9093 P100 when 99.97% is required.
It is never appropriate for IDLH or oxygen-deficient atmospheres. For where particulate filters fit relative to gas protection, see organic vapor vs P100 and the P100 vs N95 difference.
Who Should Use This Filter?
The D3078 may be appropriate for HF-800 and FF-800 users who want P95 particulate protection in a single-pair pack, including:
- Kit builds and starter sets bundling a facepiece with one pair of filters
- Fit-testing, trials, and evaluation before committing to a larger pack
- Occasional or single-task users who do not consume filters in volume
- Operations with oil mists where P95 oil resistance is needed but P100 is not required
For platform pairing, see the best cartridges for the HF-800 series and browse the 3M respirator filters and cartridges collection.
Who Should Not Use This Filter?
The D3078 is the wrong tool outside its P95 particulate role:
- You face gases or vapors — a particulate filter offers no gas/vapor protection; use a D8003 or combination cartridge.
- You need P100 99.97% efficiency — step up to the D9093 P100 filter.
- You buy particulate filters in volume — the standard-pack sibling D3071 is usually more economical.
- You only need to extend a cartridge's life — use a D7P71 prefilter, not a standalone filter.
Secure Click Compatibility
The D3078 is built for the 3M Secure Click HF-800 half-face and FF-800 full-face respirators, seating with the audible Secure Click latch — see our HF-800 review and Secure Click vs bayonet respirators. It does not fit 3M bayonet respirators (the legacy 6000, 7500, and FF-400 use a bayonet connection). Platforms are not universal — see are respirator cartridges universal?
D8000 vs D809xx vs D9000 vs D7000: Where This Product Fits
The Secure Click families show exactly where the D3078 sits:
- D8000 series — gas/vapor cartridges only (e.g., D8001, D8006). No particulate filter.
- D809xx series — combination cartridge/filter units with integrated P100 (e.g., D80921, D80923, D80926).
- D9000 / D30xx series — particulate filters only. The D3078 (P95) lives here, the single-pair sibling of the D3071, with the D9093 P100 above it.
- D7000 series — N95/P95 prefilters (D7N11, D7P71) used to extend cartridge/filter life, not for primary protection.
For the gas-versus-combination decision when a gas hazard is also present, see gas cartridge vs combination cartridge.
Best Applications
The D3078 is at its best where a single pair of P95 filters is exactly what is needed: building a starter kit around a new facepiece, running a fit test or trial, equipping an occasional user, or a low-volume task with oil mists where oil resistance matters but P100 is not required. It is the small-pack way to put proven P95 protection on a Secure Click respirator. See how it fits alongside the rest of the range in the 3M Secure Click cartridge and filter guide and the 3M respirator cartridge guide.
Key Limitations
- P95, not P100 — 95% efficiency; where 99.97% is required, use the D9093.
- No gas/vapor protection — particulate only; pair with a cartridge for gases.
- Single-pair pack — less economical than the D3071 for high-volume use.
- Will not seal over facial hair at the respirator sealing surface.
- Finite life — replace when resistance rises or it is soiled; see how long respirator cartridges last.

How It Supports a Secure Click Respirator Setup
On an HF-800 or FF-800, the D3078 is the single-pair way to put P95 particulate protection on the facepiece — ideal in a starter kit or for an occasional user. As consumption grows, most programs move to the standard-pack D3071 for the same protection, keep D9093 P100 filters for higher-efficiency jobs, and add gas/vapor cartridges such as the D8006 for chemical work — all on one reusable facepiece. Browse the full 3M respirator filters and cartridges collection.
Final Verdict
The 3M Secure Click D3078 is a dependable P95 particulate filter and a 4.5/5, distinguished from the D3071 only by its single-pair pack. Oil-resistant and 95% efficient, it is the convenient small-pack choice for kit builds, trials, and low-volume use where the 99.97% of a P100 is not required. Like any particulate filter it offers no gas or vapor protection, so pair the platform with a cartridge when gases are present. For high-volume stocking of the same P95, choose the sibling D3071; when you need the highest efficiency, step up to the D9093 P100. Always confirm the filter matches your contaminants, and follow the manufacturer's instructions and your respiratory protection program.
Frequently Asked Questions
What does the 3M Secure Click D3078 protect against?
It is a P95 particulate filter that captures at least 95% of all particulate, including oil-based aerosols. It provides no gas or vapor protection — use a cartridge separately for gases.
How is the D3078 different from the D3071?
Same P95 protection class; they differ by pack and form. The D3078 is sold as a single pair; the D3071 fits standard stocking. Choose by how you stock filters.
Is the D3078 a P100 filter?
No — it is P95 (95%, oil-resistant), not P100 (99.97%). Where the highest efficiency is required, step up to the D9093.
Is the D3078 oil-resistant?
Yes — the P in P95 means oil-resistant, so it can be used around oil mists. It provides 95% efficiency, not the 99.97% of a P100.
Does the D3078 protect against gases or vapors?
No — it is particulate-only. For gases, use a gas/vapor cartridge such as a D8006 or a combination cartridge.
Does the D3078 work with HF-800 and FF-800 respirators?
Yes — it seats on the HF-800 and FF-800 with the Secure Click latch. It does not fit 3M bayonet respirators.
When should the D3078 P95 filter be replaced?
Replace it when breathing resistance rises or it is soiled, damaged, or contaminated. Filters are replaced rather than cleaned; see how long respirator cartridges last.
Why buy the D3078 single pair instead of the D3071?
The single pair suits kit builds, trials, and occasional use. If you go through filters in volume, the D3071 is usually more economical for the same protection.
Should I choose the D3078 P95 or the D9093 P100?
Use the D3078 where 95% meets your assessment and you want a lighter, lower-cost filter; use the D9093 where 99.97% is required. Both are oil-resistant.
Is there a P95 filter with nuisance hydrogen fluoride relief?
Yes — the D3076HF adds below-OEL nuisance HF relief. That is odor relief only, not gas/vapor protection; use a proper cartridge if HF is at or above the limit.
What is the difference between P95 and P100?
Both are oil-resistant; P95 is 95% efficient, P100 is 99.97%. The D3078 is P95; the D9093 is P100. See P95 vs P100.
