3M Secure Click D3078 P95 Respirator Filter, 1 Pair

Read our hands-on 3M Secure Click D3078 review for field-tested buyer notes.

3M Secure Click D3078 Overview

The 3M Secure Click D3078 is a NIOSH-approved P95 particulate filter for the 3M Secure Click platform, sold as a single pair (two filters). It captures dusts, mists, and fumes — including oil-based aerosols — and attaches via the Secure Click half-turn bayonet to 3M HF-800 half-facepiece and FF-800 full-facepiece respirators only. The D3078 is a soft-shell, standard-profile Secure Click filter at the P95 efficiency class.

This is a particulate filter only — it removes particles but provides no protection against gases or vapors of any kind. It is designed exclusively for the Secure Click platform; it will not fit 3M bayonet respirators. For related context, read respirator filter types explained and P100 vs N95 — which do you need, or browse the full 3M respirator filters and cartridges collection.

Where the D3078 Fits in Respirator Selection

The D3078 sits in the Secure Click D30xx particulate filter family at the P95 efficiency level. Before ordering, confirm two things: your respirator is a Secure Click HF-800 or FF-800 (not a bayonet facepiece), and your hazard is particulate — not gas or vapor.

• Secure Click + P95 + single pair → the D3078 (this product).
• Secure Click + P95 + multi-pair or bulk → the D3071 is typically the lower-cost multi-pair P95 option.
• Secure Click + P100 required (silica, lead, asbestos) → the D3091 (P100). See best respirator for silica dust.
• Secure Click + hard-shell P100 → the D9093 hard-case P100 filter.
• 3M bayonet respirator instead → Secure Click filters will not fit. Use a bayonet filter and consult the how to choose a respirator cartridge guide.
• Gas or vapor present → a Secure Click cartridge, not a filter. See the 3M filters and cartridges collection for Secure Click gas-cartridge options.

Who Should Buy the 3M Secure Click D3078?

Buy the D3078 if you run a 3M HF-800 or FF-800 Secure Click respirator, your hazard is particulate dust, mist, or fume, and you need a single pair rather than a multi-pair bulk order.

Choose a different filter if:

• You want the lowest-cost Secure Click P95 for bulk programs → the D3071 multi-pair option.
• Your hazard requires P100 efficiency (silica, lead, asbestos) → the D3091 (P100).
• You need P100 in a hard-shell housing → the D9093 hard-case P100.
• You need P100 with nuisance acid gas relief → the D3096.
• You want N95 in volume on Secure Click → the D7N11 N95 20-pack.
• You run a bayonet respirator → Secure Click filters will not attach to bayonet facepieces.

What Does the D3078 Protect Against?

What the D3078 Does NOT Protect Against

• Organic vapor
• Acid gas
• Ammonia / methylamine
• Formaldehyde
• Hydrogen fluoride
• Carbon monoxide
• Oxygen deficiency
• IDLH conditions
• Unknown atmospheres

Safety: The D3078 is a particulate filter only and provides no gas or vapor protection. No air-purifying filter adds oxygen. It fits only 3M Secure Click HF-800 and FF-800 respirators — do not attempt to use it on 3M bayonet respirators (6000 / 6500QL / 7500 / 7800S / FF-400). Oxygen-deficient, unknown-composition, and IDLH atmospheres require supplied air or SCBA as specified by a qualified industrial hygienist or safety professional. Filter selection should follow a documented hazard assessment per OSHA 1910.134.

Best Applications for the D3078

General Dust, Mist & Fume Work (P95)

The D3078 suits P95 particulate tasks — sanding, grinding, spray painting without solvent vapor, and general dust — on a Secure Click respirator. At P95 efficiency it handles the majority of workplace dust and particulate mist exposures. Where a substance-specific regulation calls for P100, step up to the Secure Click D3091 (P100).

Oil-Based Aerosols & Metalworking Mist

Because it is P-rated (oil-proof), the D3078 handles oil-based metalworking fluid mist that N-series (N95/N99/N100) filters are not rated for. Review the rating-class logic in respirator filter types explained or compare classes in the respirator cartridge color chart.

Single-Pair Top-Off or Trial Purchases

The 1-pair format makes the D3078 practical for topping off a kit, trialing the Secure Click filter before bulk ordering, or covering a short-duration job. For bulk programs and multi-pair pricing, compare the D3071 and browse all options in the 3M respirator filters and cartridges collection.

Welding Fume (General Particulate)

For welding-fume work at the P95 class, the D3078 captures the particulate component of welding fume on a Secure Click respirator. For heavier fume or situations where P100 is required, use the D3091. See the best respirator for welding fumes guide for a full breakdown.

3M Secure Click D3078 Pros & Cons

Compatible 3M Respirators

The D3078 uses the 3M Secure Click half-turn bayonet mount and is compatible only with Secure Click platform respirators. It is NOT compatible with any standard 3M bayonet respirators — this is a hard platform incompatibility, not a preference.

Browse compatible respirators in the 3M half-face respirators collection and the 3M full-face mask respirators collection.

D3078 vs Other 3M Secure Click Filters

D3078 vs D3071 — Single Pair vs Bulk P95

Both are Secure Click P95 soft-shell filters at the same efficiency class. The key difference is pack format: the D3078 ships as a single pair, while the D3071 is the multi-pair bulk option. If you run through filters at volume or supply a crew, the D3071 delivers the same P95 protection at a lower per-pair cost. Choose the D3078 when you need exactly one replacement pair without committing to a larger quantity.

D3078 vs D3091 — P95 vs P100

This is an efficiency-class decision. The D3078 is P95 (captures ≥95% of particles); the D3091 is P100 (≥99.97%) and is the standard class for regulated substances like silica dust, lead, and asbestos. Buy the D3078 when P95 satisfies your hazard assessment. Buy the D3091 when a substance-specific standard requires P100 efficiency. For guidance, see P100 vs N95 — which do you need.

D3078 vs D3076HF — Standard P95 vs HF Relief

The D3078 is a straight P95 particulate filter with no chemical relief. The D3076HF adds nuisance-level hydrogen fluoride and acid gas relief at the same P95 particulate efficiency. If your work involves HF or acid environments at nuisance levels alongside dust, the D3076HF is the better fit; for pure particulate work with no chemical exposure, the D3078 suffices.

3M Secure Click D3078 Quick Answers

What is the 3M Secure Click D3078?

The 3M Secure Click D3078 is a NIOSH-approved P95 particulate respirator filter sold as a single pair (1 pair = 2 filters). It attaches via the Secure Click half-turn bayonet to 3M HF-800 and FF-800 respirators and is rated oil-proof (P-series), capturing ≥95% of airborne particles including oil-based aerosols.

What respirators does the D3078 fit?

The D3078 fits only 3M Secure Click HF-800 (half facepiece) and FF-800 (full facepiece) respirators. It is incompatible with 3M 6000 series, 6500QL, 7500, 7800S, FF-400, and any other standard bayonet respirator.

Is the D3078 P95 or P100?

The D3078 is P95, capturing at least 95% of airborne particles and rated oil-proof ("P" class). For P100 efficiency (99.97%) on the Secure Click platform, use the D3091.

Does the D3078 protect against gases or vapors?

No. The D3078 is a particulate filter only and provides zero gas or vapor protection. For chemical vapor protection on Secure Click, use a Secure Click gas cartridge such as the D8001 (OV) or D8003 (OV/AG).

How many filters are in a D3078 pack?

One pair — meaning two individual filters. Respirators use two filters simultaneously (one per exhalation valve port), so one pack equips a single respirator for one change.

3M Secure Click D3078 Frequently Asked Questions

What is the 3M Secure Click D3078 used for?

The D3078 is used for P95 particulate protection — dusts, mists, and fumes including oil-based aerosols — on 3M Secure Click HF-800 and FF-800 respirators. It is the single-pair format of the Secure Click P95 soft-shell filter line.

Does the D3078 fit 3M bayonet respirators like the 6000 or 7500?

No. The D3078 uses the Secure Click half-turn bayonet mount, which is physically incompatible with 3M's standard bayonet respirators including the 6000, 6500QL, 7500, 7800S, and FF-400 series. It will not attach to those facepieces.

Is the D3078 the same as the D3071?

Both are Secure Click P95 soft-shell filters at the same efficiency level. The D3078 is sold as a single pair; the D3071 is the multi-pair option. For bulk programs, the D3071 delivers the same P95 protection at a lower per-pair cost. Choose the D3078 when you need only one pair.

Is the D3078 oil-resistant?

Yes. The "P" in P95 means oil-proof — the D3078 is rated for oil-based mists and aerosols, such as metalworking-fluid mist, that N-series filters (N95, N99, N100) are not approved for.

Can the D3078 protect against silica dust?

For crystalline silica, OSHA regulations and most safety programs specify P100 efficiency. The D3078 is P95, which is below the P100 standard typically required for silica. Use the Secure Click D3091 (P100) for silica, lead, and asbestos applications.

Does the D3078 protect against organic vapor?

No. The D3078 is a particulate-only filter. It provides no protection against organic vapors, acid gases, ammonia, formaldehyde, or any other chemical vapor. For vapor protection on Secure Click, use a gas-rated Secure Click cartridge.

How many filters come in one D3078 pack?

One pack contains one pair — two individual filters. A respirator requires two filters (one on each side), so one pack equips one respirator for a single filter change.

What is the difference between the D3078 and D3091?

The D3078 is P95 (≥95% efficiency); the D3091 is P100 (≥99.97% efficiency). Both fit the Secure Click platform. Buy the D3078 for general dust and oil-mist work where P95 satisfies your hazard assessment; buy the D3091 when P100 is required by regulation or your safety program.

Can I use the D3078 with an HF-800 half-mask respirator?

Yes. The 3M HF-800 is a Secure Click half-facepiece and is the primary compatible platform for the D3078. The filter's half-turn bayonet seats with an audible click.

What is the difference between the D3078 and D3076HF?

The D3078 is a straight P95 particulate filter with no chemical relief. The D3076HF adds nuisance-level hydrogen fluoride and acid gas relief at the same P95 efficiency. If your work involves HF or acid environments, use the D3076HF; for particulate-only exposures, the D3078 is sufficient.

When should I replace the D3078?

Replace the D3078 when it is physically damaged, soiled, or noticeably harder to breathe through than new, or according to the change schedule in your employer's written respiratory protection program. There is no fixed hour limit — replacement is condition- and exposure-based.

Is the D3078 a hard-shell or soft-shell filter?

The D3078 is a soft-shell (flat-fold or standard-profile) filter. For a hard-shell Secure Click P100 option, see the D9093 hard-case P100 filter.

Is the D3078 approved for welding fume?

The D3078 captures particulate welding fume at P95 efficiency on a Secure Click respirator. For welding situations where P100 is specified or where the fume mix is heavier, use the D3091. Consult the best respirator for welding fumes guide for application-specific guidance.
