3M Secure Click D9093CB P100 Hard Case Filter with Nuisance Acid Gas Relief, Case/144

Read our hands-on 3M Secure Click D9093CB review for field-tested buyer notes.

3M Secure Click D9093CB Overview

The 3M Secure Click D9093CB is a NIOSH-approved P100 hard-case particulate filter with nuisance acid gas relief sold in a case of 144 individual filters (72 pairs) for 3M Secure Click HF-800 and FF-800 respirators. It uses a half-turn bayonet Secure Click mount that locks with an audible click, and its rigid polycarbonate housing protects the filter media in demanding environments. The activated-carbon sorbent layer provides nuisance-level odor relief only — it is not TC-23C rated for regulatory acid gas protection.

This case-quantity listing is the procurement choice for facilities and safety programs that go through Secure Click P100 filters at volume and want the nuisance acid gas odor control built in. If you need the same combination in smaller quantities, the D3096 (soft shell, smaller pack) is the direct alternative; for plain P100 without acid gas relief in the same hard case, see the D9093.

Where the D9093CB Fits in Respirator Selection

Two conditions must both be true before the D9093CB is the right order: your respirators are Secure Click platform (HF-800 or FF-800), and your program buys at case volume.

• Secure Click + P100 + nuisance acid gas odor + case quantity → the D9093CB (this listing).
• Secure Click + P100 + nuisance acid gas + smaller pack → the soft-shell D3096.
• Secure Click + P100 + nuisance OV odor (not acid gas) → the D3097.
• Secure Click + P100 only, no gas relief needed → the hard-case D9093 or soft-shell D3091.
• Regulatory acid gas protection needed → the D9093CB is not sufficient; you need a TC-23C-approved cartridge. See the how to choose a respirator cartridge guide.
• 3M bayonet respirator → Secure Click filters physically will not fit; review the 3M filter and cartridge guide for bayonet options.

Who Should Buy the 3M Secure Click D9093CB?

Buy the D9093CB if your facility runs 3M HF-800 or FF-800 Secure Click respirators, your workers encounter P100-level particulate hazards with incidental acid gas odors (below regulatory action levels), and you purchase filter stock in case quantities to manage inventory efficiently.

Choose a different product if:

• You need single pairs or smaller packs → the soft-shell D3096 (P100 + nuisance acid gas).
• Your acid gas hazard requires regulatory protection (TC-23C) → a combination cartridge; see the respirator filter types explained guide.
• You need HF (hydrogen fluoride) protection → the D9093C (hard case, P100 + HF).
• You need organic vapor + P100 in one cartridge → the D80921 or D80923.
• You run a 3M bayonet respirator → Secure Click filters cannot mount on bayonet facepieces.

What Does the D9093CB Protect Against?

What the D9093CB Does NOT Protect Against

• Regulatory-level acid gas
• Organic vapor
• Carbon monoxide
• Formaldehyde
• Ammonia
• Hydrogen fluoride (beyond nuisance)
• Oxygen deficiency
• IDLH atmospheres
• Unknown hazard atmospheres

Safety: The D9093CB is a P100 particulate filter with nuisance acid gas odor relief only — the activated carbon is not TC-23C approved and does not provide regulatory-level protection against acid gases at action-level or above. No filter adds oxygen. It fits exclusively the 3M Secure Click platform; forcing it onto a bayonet facepiece will result in an unseated, non-sealing connection. Oxygen-deficient, unknown, and IDLH atmospheres require supplied air, SCBA, or another solution specified by a qualified safety professional. Filter selection must be based on a completed hazard assessment and a written respiratory protection program.

Best Applications for the D9093CB

Silica, Lead, and Regulated-Substance Environments with Incidental Acid Gas Odors

Facilities where workers grind, cut, or otherwise disturb silica-containing materials, lead paint, or other NIOSH P100-listed substances — and where ambient acid gas odors occur at nuisance levels — get P100 particulate efficiency plus odor relief in one filter. The hard case adds mechanical protection during storage and use in abrasive environments. For silica-specific buying guidance see best respirator for silica dust 2026.

High-Volume Industrial Programs on Secure Click Respirators

Safety managers running large Secure Click programs — chemical plants, smelters, battery manufacturers, mining operations — benefit from the Case/144 pack format. Bulk ordering reduces per-pair cost and ensures consistent filter stock. Browse the full P100 respirator filters collection to compare in-stock options.

Metalworking and Welding with Oil-Based Mist and Acid Gas Odors

The "P" rating covers oil-based metalworking mists that N-class filters are not rated for, and the nuisance acid gas sorbent handles mild pickling-acid or flux odors at below-action-level concentrations. For heavier fume applications, review the best respirator for welding fumes guide.

Programs Standardized on the Secure Click Hard-Case Platform

Some Secure Click programs specifically specify the hard-shell D9093 family for durability — the rigid polycarbonate housing resists crushing and debris during filter storage. Where acid gas odor is not a factor, the same hard case without the sorbent layer is the D9093. All options are in the 3M filters and cartridges collection.

3M Secure Click D9093CB Pros & Cons

Compatible 3M Respirators

The D9093CB uses the 3M Secure Click half-turn bayonet mount and fits only the Secure Click platform. It is incompatible with all standard 3M bayonet respirators — including the 6000, 6500QL, 7500, 7800S, and FF-400 series.

D9093CB vs Other 3M Secure Click P100 Filters

D9093CB vs D9093 — Nuisance Acid Gas Relief vs Plain P100

Both are hard-case Secure Click P100 filters sold in case quantities. The D9093CB adds an activated-carbon sorbent layer for nuisance acid gas odor relief; the plain D9093 provides P100 particulate filtration only. Buy the D9093CB where ambient acid gas odors are a comfort or mild nuisance concern; choose the D9093 where only particulate control is needed and you do not want to pay for sorbent capacity you will not use.

D9093CB vs D3096 — Hard Case vs Soft Shell

The D9093CB and the D3096 provide the same protection class — P100 plus nuisance acid gas relief — but differ in housing and pack size. The D9093CB uses a rigid polycarbonate hard case (more durable in abrasive settings) and sells in Case/144. The D3096 has a soft shell and is available in smaller pack quantities. Choose the D9093CB for high-volume, hard-use programs; the D3096 when you need smaller quantities or prefer a lighter housing.

D9093CB vs D9093C — Acid Gas vs Hydrogen Fluoride Nuisance Relief

The D9093CB addresses nuisance-level acid gas odors (hydrochloric acid, sulfur dioxide, and similar). The D9093C is the same hard-case P100 filter configured for hydrogen fluoride (HF) nuisance relief — a chemically distinct hazard. Match the sorbent to the specific nuisance gas in your environment; do not substitute one for the other when the hazard identity differs.

3M Secure Click D9093CB Quick Answers

What is the 3M Secure Click D9093CB?

The D9093CB is a NIOSH-approved P100 hard-case particulate filter with nuisance acid gas odor relief, sold in a case of 144 filters (72 pairs) for 3M Secure Click HF-800 and FF-800 respirators. It captures ≥99.97% of airborne particles, and its activated-carbon layer reduces nuisance-level acid gas odors. It is not TC-23C approved for regulatory acid gas protection.

What respirators does the D9093CB fit?

The D9093CB fits only 3M Secure Click HF-800 and FF-800 platform respirators — specifically the HF-801, HF-802, HF-803, FF-801, FF-802, and FF-803. It does not fit any 3M bayonet respirator, including the 6000, 6500QL, 7500, 7800S, or FF-400 series.

Does the D9093CB protect against acid gas?

The D9093CB provides nuisance-level acid gas odor relief through an activated-carbon sorbent — it is not TC-23C certified and does not provide regulatory-level acid gas protection. If your exposure exceeds nuisance concentrations or requires OSHA compliance for acid gas, you need a TC-23C-approved cartridge.

How many filters are in the D9093CB case?

The case contains 144 individual filters, which equals 72 pairs. This is a bulk case-quantity SKU; it is not available in smaller packs under this handle. For smaller quantities with the same protection, see the soft-shell D3096.

What is the difference between the D9093CB and D9093C?

Both are hard-case Secure Click P100 filters. The D9093CB has nuisance acid gas relief (for acids like HCl, SO2); the D9093C has nuisance hydrogen fluoride (HF) relief. They address different nuisance-gas profiles — match the sorbent to the specific hazard in your workplace.

Is the D9093CB P100 or a lower class?

It is P100 — the highest NIOSH particulate efficiency class, capturing ≥99.97% of airborne particles and rated oil-proof. This makes it suitable for silica, lead, asbestos, and other high-hazard regulated particulates.

Why does the D9093CB have a hard case instead of soft shell?

The rigid polycarbonate housing protects the filter media from crushing and debris during storage and use in demanding industrial environments. Programs that store filters in toolboxes, lockers, or high-traffic areas often specify the hard-case D9093 family to reduce filter damage and waste.

3M Secure Click D9093CB Frequently Asked Questions

What is the 3M Secure Click D9093CB used for?

The D9093CB is used for P100 particulate filtration — dusts, mists, fumes, and oil-based aerosols — combined with nuisance acid gas odor relief, on 3M Secure Click HF-800 and FF-800 respirators. It is sold as a Case/144 (72 pairs) for high-volume industrial programs.

Does the D9093CB fit 3M bayonet respirators?

No. The D9093CB uses the Secure Click half-turn bayonet mount and is compatible only with 3M Secure Click HF-800 and FF-800 platform respirators. It will not fit and cannot be made to fit 3M bayonet facepieces such as the 6000, 6500QL, 7500, 7800S, or FF-400 series.

Is the D9093CB's acid gas protection regulatory-level?

No. The activated-carbon sorbent provides nuisance-level odor relief only. The D9093CB is not TC-23C certified. For regulatory acid gas protection at action-level or PEL concentrations, a TC-23C-approved acid gas cartridge is required.

What is the pack quantity for the D9093CB?

The D9093CB comes in a case of 144 individual filters, equal to 72 pairs. This is the only pack format for this SKU. For smaller quantities with the same P100 + nuisance acid gas protection, see the D3096.

How does the D9093CB differ from the D9093?

The D9093 is a plain P100 hard-case filter with no gas relief layer. The D9093CB adds activated carbon for nuisance acid gas odor control. Both use the same hard polycarbonate housing and Secure Click mount. Choose the D9093CB only if nuisance acid gas odor is a documented concern in your environment.

How does the D9093CB differ from the D3096?

Both deliver P100 + nuisance acid gas relief on the Secure Click platform. The D9093CB has a rigid hard-case housing and sells in Case/144. The D3096 uses a softer shell and is available in smaller pack quantities. For bulk procurement or hard-use environments, the D9093CB is the better choice; for flexibility, the D3096.

Can the D9093CB be used for silica dust?

Yes. P100 is the class recommended for regulated silica work under OSHA's silica standard (1910.1053 / 1926.1153). The D9093CB provides P100 efficiency. The nuisance acid gas layer does not diminish particulate protection; it adds odor-control functionality.

Is the D9093CB suitable for oil-based mists?

Yes. The "P" rating means the filter is oil-proof and maintains its efficiency rating in the presence of oil-based aerosols. N-class filters are not rated for oil mists; P-class filters are.

How do I know when to replace the D9093CB?

Replace the filter when it is physically damaged, soiled, or becomes hard to breathe through. Follow your employer's written respiratory protection program for scheduled change-out intervals, especially when acid gas odors become detectable through the filter — that signals sorbent saturation.

What does "nuisance acid gas relief" mean on the D9093CB?

It means the filter contains an activated-carbon sorbent that adsorbs low-level acid gas vapors to reduce nuisance odors at below-action-level concentrations. It is not a full acid gas cartridge, does not pass TC-23C testing, and is not appropriate for environments where acid gas concentration is at or above the OSHA action level or PEL.

Will the D9093CB work on the FF-800 full-face respirator?

Yes. The FF-800 is part of the 3M Secure Click full-face platform and uses the same Secure Click half-turn bayonet mount. The D9093CB seats with an audible click on both HF-800 half-face and FF-800 full-face Secure Click facepieces.

Why is the D9093CB sold in a case of 144?

The Case/144 format is designed for industrial facilities and safety programs with high filter consumption. Bulk case purchasing reduces per-pair cost, simplifies procurement, and ensures stocking levels for crews that change filters frequently. Programs needing smaller quantities should order the D3096 instead.
