3M Secure Click D80926 Multi-Gas + P100 Combination Cartridge Review (2026)

Is the 3M Secure Click D80926 the right multi-gas + P100 cartridge for variable or high-complexity chemical exposure?

Short answer: Yes -- when your hazard assessment documents the broadest chemical exposure profile in the Secure Click lineup (organic vapors, acid gases, ammonia, methylamine, formaldehyde, and airborne particulate simultaneously or interchangeably), the 3M Secure Click D80926 is the correct cartridge. It is the ceiling of the Secure Click D-series combination cartridge line. If your SDS does not list ammonia, methylamine, or formaldehyde alongside the OV and acid gas hazards, the D80923 provides equivalent protection at lower cost. If your hazard is OV plus particulate only, the D80921 is the correct default. The D80926 exists for the specific cases where no narrower cartridge in the line covers the full documented hazard -- or where safety managers need a single SKU across a diverse crew with variable chemical exposure assignments.

3M Secure Click D80926 Multi-Gas + P100 Combination Cartridge Review (2026)

The 3M Secure Click D80926 is the highest-coverage combination cartridge in 3M's Secure Click D-series -- the only Secure Click cartridge that pairs the full multi-gas sorbent profile (organic vapor, acid gases, ammonia, methylamine, formaldehyde) with an integrated P100 filter (99.97% at 0.3 µm, oil-resistant). It is sold as a 1-pair pack and fits the full Secure Click platform: HF-801, HF-802, and HF-803 half-face respirators at APF 10, and the FF-800 full-face respirator at APF 50. The D80926 is the Secure Click equivalent of the legacy 3M 60926 bayonet combination cartridge.

This review covers what the D80926 actually protects against -- and what it does not (isocyanates, CO) -- how it positions within the full Secure Click D-series lineup, which specific applications genuinely require the D80926 versus a less expensive narrower cartridge, and the cost and compliance implications of specifying the D80926 as a program default versus a targeted selection. The D80926 is the right answer for a specific set of hazard profiles. It is also the most expensive Secure Click combination cartridge, which makes it the most frequently over-specified. This review helps you determine whether your hazard profile actually requires the D80926 or whether a more targeted cartridge is the correct answer.

Key applications that genuinely require the D80926: wastewater treatment spray operations where ammonia off-gassing occurs alongside organic chemical exposure and aerosol; pesticide spray applications involving mixed OV, acid gas, and ammonia-based formulation components; formaldehyde-exposed environments where spray application generates both vapor and aerosol (anatomy specimen work, some composite manufacturing); chemical processing facilities with variable or rotating chemical assignments where one cartridge must cover a documented range of gas types; and safety programs serving diverse crews where the cost and logistics burden of stocking multiple cartridge SKUs is operationally worse than the cost premium of a single D80926 specification.

Editorial verdict -- 3M Secure Click D80926: 4.5 / 5
The correct Secure Click cartridge when the full multi-gas + P100 hazard profile is documented -- broadest chemical coverage in the line, integrated P100, Secure Click positive-lock on HF-800 and FF-800 platforms. Deductions: highest cost per pair in the Secure Click combination cartridge line; no ESLI; no isocyanate or carbon monoxide coverage (critical exclusions for chemical processing programs); justified only when ammonia or formaldehyde are confirmed in the hazard assessment -- otherwise the D80923 or D80921 is the right choice.

Who the 3M Secure Click D80926 is for

• Wastewater treatment spray operators -- ammonia off-gassing is a documented hazard at wastewater treatment plants, particularly in aeration basins, sludge handling, and digester operations where spray equipment generates aerosol alongside ammonia and organic chemical exposure
• Pesticide spray applicators -- commercial pesticide formulations can include organic solvent carriers, acid gas components, and ammonia-based active ingredients or adjuvants; the D80926 covers the multi-chemistry profile common in professional pest management and agricultural spray
• Formaldehyde-exposed spray application environments -- anatomy and pathology specimen preparation involving formaldehyde spray, composite manufacturing using formaldehyde-based resin spray, or MDF-adjacent spray operations where formaldehyde off-gassing from freshly cut board combines with spray aerosol
• Chemical processing and manufacturing workers rotating through multiple process areas where the chemical hazard mix includes OV, acid gases, and ammonia or formaldehyde -- and where a single-cartridge specification across the crew is operationally simpler than multi-SKU stocking
• Safety managers building single-SKU programs for crews with diverse and variable chemical exposure assignments -- the D80926 can serve as the program's universal Secure Click combination cartridge when the cost premium is justified by the logistics savings of one SKU covering the full range of documented crew hazards
• Industrial refrigeration maintenance spray environments -- anhydrous ammonia and ammonia refrigerant leaks create acute ammonia exposure that can combine with organic refrigerant oils and aerosol from leak spray testing or equipment cleaning
• Workers stepping up from the D80923 whose updated hazard assessment confirmed ammonia or formaldehyde presence that had been previously absent or uncharacterized in the exposure profile

Browse the full 3M respirator filters and cartridges collection and use your SDS chemical inventory to confirm whether your hazard profile requires the D80926's full multi-gas coverage or whether a targeted narrower cartridge is the appropriate specification.

What the 3M Secure Click D80926 does well

Maximum chemical coverage in the Secure Click combination cartridge line

The D80926 is the only Secure Click combination cartridge that simultaneously covers organic vapors, acid gases (Cl2, HCl, SO2, HF), ammonia (NH3), methylamine (CH3NH2), formaldehyde (HCHO), and P100 particulate in a single Secure Click housing. No other D-series combination cartridge covers this full profile. The D80923 covers everything except ammonia and formaldehyde; the D80921 covers everything except acid gas, ammonia, and formaldehyde. When the documented hazard profile includes any of ammonia or formaldehyde alongside organic vapor, acid gas, and particulate, the D80926 is the only Secure Click combination cartridge that is adequate. The alternative in the bayonet system -- assembling a 6006 multi-gas cartridge, 501 retainer, and 2091 P100 filter per side -- is a three-component-per-side assembly process that the D80926 replaces with a single push-click installation.

Single SKU coverage for variable and rotating chemical exposure assignments

In facilities where workers rotate through multiple process areas with different chemical hazard profiles, stocking multiple cartridge SKUs creates inventory complexity and -- more critically -- the risk of wrong-cartridge selection during a shift change or task rotation. When the documented hazard inventory across all rotations includes at least one task requiring multi-gas coverage (OV + AG + NH3 + HCHO), specifying the D80926 as the single program cartridge eliminates the selection ambiguity. The D80926's coverage envelope is broad enough to serve the full rotation without the worker or supervisor making cartridge selection decisions in the field. This is a legitimate justification for the D80926's cost premium in programs where hazard diversity and field selection errors are the greater operational risk.

Ammonia and formaldehyde coverage -- the critical differentiator

The specific chemicals that distinguish the D80926 from the D80923 are ammonia (NH3), methylamine (CH3NH2), and formaldehyde (HCHO). These are not obscure edge-case hazards -- ammonia is a documented exposure hazard in wastewater treatment, agricultural spray, refrigeration maintenance, and some chemical manufacturing; formaldehyde is a documented hazard in anatomy, histology, composite manufacturing, and MDF processing. Methylamine is present in some industrial chemical synthesis and processing streams. The D80926 is the correct call when any of these appear on your SDS hazardous ingredients list alongside the OV and acid gas profile already covered by the D80923. Not because "more coverage is better" -- but because the alternative (using the D80923 in an ammonia environment) leaves a documented hazard completely unaddressed.

Secure Click positive-lock in high-complexity environments

The D80926's Secure Click positive-lock mechanism provides the same audible-confirmation donning verification as the D80921 and D80923 -- particularly valuable in chemical processing environments where the consequence of an unseated cartridge is exposure to a multi-gas hazard profile that includes acid gases and ammonia. Workers in full protective ensembles (gloves, goggles, aprons) in ammonia or formaldehyde environments benefit from the positive-lock confirmation the bayonet twist-and-press does not reliably deliver under impaired dexterity conditions. The click is the confirmation; the worker does not need to visually inspect the cartridge seat or rely on tactile feedback through protective gloves.

Full Secure Click platform compatibility -- one cartridge across the fleet

The D80926 fits every facepiece in the Secure Click platform: HF-801 (small), HF-802 (medium), and HF-803 (large) half-face respirators at APF 10, and the FF-800 full-face respirator at APF 50. One D80926 pair serves the entire HF-800 fleet regardless of facepiece size. For chemical processing programs with multi-size facepiece inventories and multi-gas hazard profiles, this means a single cartridge SKU covers every worker in the program. See the compatible respirators section below.

NIOSH TC-23C combination approval -- single device regulatory documentation

The D80926 carries a NIOSH TC-23C combination cartridge approval covering the full multi-gas plus P100 profile. As with the D80923 and D80921, this single approval covers the complete hazard scope the cartridge is rated for -- no separate filter approval, no stacked assembly, no multi-document approval chain. For compliance programs where regulatory documentation simplicity matters, the D80926's TC-23C approval covers OV, AG, NH3, CH3NH2, HCHO, and P100 under one certificate of approval. Verify the specific TC number on the NIOSH Certified Equipment List and record it in your written respiratory protection program.

Where the 3M Secure Click D80926 falls short

No isocyanate coverage -- the most critical shared limitation

The D80926 does not protect against isocyanate vapors (MDI, HDI, TDI, IPDI, or other diisocyanates). This is a universal limitation of all air-purifying cartridges -- not specific to the D80926 or the Secure Click system. If your chemical processing environment or coating application involves any isocyanate-containing material, a supplied-air respirator (SAR) or SCBA is required under OSHA 29 CFR 1910.134. The D80926's broad multi-gas coverage does not extend to this class of hazard under any circumstances. Check every coating, adhesive, and chemical SDS in your hazard inventory for any diisocyanate or polyisocyanate listing before specifying an air-purifying cartridge as program protection.

No carbon monoxide (CO) coverage

The D80926 does not protect against carbon monoxide. CO exposure from combustion engines, forklifts operating in enclosed spaces, generator exhaust, or chemical process combustion byproducts requires a CO-specific supplied-air respirator, SCBA, or -- for combined CO and chemical vapor exposure -- a specialized combination unit. The D80926's organic vapor sorbent does not adsorb CO; no activated carbon cartridge does. In chemical processing environments where combustion equipment operates adjacent to the spray or vapor exposure area covered by the D80926, the CO hazard must be controlled by engineering means (ventilation, CO monitoring, equipment exclusion) -- not by the cartridge.

Most expensive Secure Click combination cartridge -- over-specification risk is real

The D80926 carries the highest per-pair cost in the Secure Click combination cartridge line. This is the correct trade for programs where the documented hazard requires its full multi-gas coverage. It is an unnecessary cost for programs where the hazard profile is adequately covered by the D80923 (no ammonia or formaldehyde) or the D80921 (no acid gas, ammonia, or formaldehyde). Before specifying the D80926 for a program because "it covers everything," conduct the SDS review to confirm that ammonia or formaldehyde are actually present in your hazard inventory. If they are not, a more targeted cartridge is the correct and more cost-effective specification.

Multi-contaminant service life calculation is more complex

The D80926's multi-gas sorbent covers five distinct chemical classes. Service life calculation for activated carbon cartridges uses 3M's Chemical Cartridge Service Life Estimation Software, which requires input of chemical identity, air concentration, relative humidity, and work rate for each contaminant. In multi-gas environments with five chemical categories, the software must be run for each contaminant type and the most conservative (shortest) service life result applied as the program's change-out interval. This calculation complexity is proportional to the number of chemicals -- the D80926 in a complex multi-gas environment requires a more thorough service life analysis than a single-gas cartridge in a simpler environment. Document all calculations in your written respiratory protection program per OSHA 1910.134(d)(3)(iii)(B).

3M Secure Click D80926 vs the full D-series cartridge lineup

Buy the D80926 if: your documented hazard profile includes organic vapors, acid gases, and ammonia or formaldehyde, alongside spray aerosol or airborne particulate. This is the correct cartridge for wastewater spray, pesticide spray, formaldehyde spray environments, and multi-hazard crews requiring a single combination cartridge SKU.

Buy the D80923 if: your hazard profile includes OV, acid gases, and P100 particulate but no ammonia or formaldehyde -- chlorinated solvent spray, acid-catalyzed coating spray, electroplating mist environments.

Buy the D80921 if: your hazard is organic vapor plus spray particulate with no acid gas, ammonia, or formaldehyde -- spray painting, solvent-borne coatings, lacquer, adhesive spray.

Buy the D8006 if: you face multi-gas exposure (OV + AG + NH3 + HCHO) without spray aerosol or particulate -- wipe-on or dip processes in multi-gas environments where no aerosol phase is generated.

Compatible 3M Secure Click respirators

The 3M Secure Click D80926 is compatible only with facepieces in the 3M Secure Click platform. It will not mount on 6000-series, 7000-series, 6500-series, or 7500-series bayonet respirators. The equivalent bayonet-system cartridge for those platforms is the 3M 60926 multi-gas combination cartridge.

In multi-gas environments where ammonia or acid gas concentrations may be variable or elevated during peak operations (e.g., ammonia refrigerant release events, acid misting surges), the transition from the HF-800 half-face (APF 10) to the FF-800 full-face (APF 50) with the same D80926 cartridge provides a meaningful protection uplift without a cartridge change. For wastewater treatment and chemical processing facilities, the FF-800 full-face is often the appropriate platform for the D80926 given the higher APF it provides and the eye and face protection it adds against acid gas splash and aerosol.

D80926 in the Secure Click vs bayonet platform decision

The D80926 is the Secure Click platform's equivalent of the 3M 60926 bayonet multi-gas combination cartridge -- same protection profile (OV + AG + NH3 + CH3NH2 + HCHO + P100), different mount system. The two are not physically interchangeable. The D80926 uses the Secure Click push-and-click positive-lock mount (HF-800 and FF-800 facepieces only); the 60926 uses the bayonet twist-and-lock mount (6000, 7000, 6500, 7500, 7800S, Ultimate FX facepieces).

For new multi-gas program builds on the Secure Click platform, the D80926 provides the same protection depth as the legacy bayonet 60926 with the operational advantages of the Secure Click system: positive-lock donning confirmation, silicone facepiece seal geometry, and a single cartridge housing that replaces the bayonet system's three-component-per-side assembly for equivalent multi-gas + P100 protection. For programs already running the 60926 on 6000/7000-series facepieces, there is no protection-based reason to switch -- but new fleet decisions should evaluate the HF-800 or FF-800 as the current platform. The full platform comparison is in the 3M Secure Click respirator filters and cartridges guide.

Total cost of ownership -- D80926 cartridge replacement budget

The D80926 is the highest-cost cartridge in the Secure Click combination line on a per-pair basis. Budget planning should account for this premium against the specific protection benefit it delivers:

• Multi-gas spray environments (wastewater spray, pesticide spray, formaldehyde spray): change-out intervals must be calculated for each contaminant separately using 3M's service life software -- the sorbent with the shortest calculated service life for the documented chemical identity and concentration drives the program's change-out interval for all contaminants
• Intermittent multi-gas exposure (refrigeration maintenance, occasional ammonia-adjacent spray): service life software output at documented peak concentrations; end-of-shift replacement is a defensible conservative default when concentrations are variable or uncharacterized
• Single-SKU program economics: programs that consolidate from multiple cartridge SKUs (D80921 + D80923 + standalone P100) to a single D80926 may offset some per-pair cost premium against reduced procurement complexity, inventory carrying costs, and field selection errors -- quantify the full program cost before concluding the D80926 is "more expensive" when alternative-SKU management costs are included

The D80926's integrated P100 eliminates the separate particulate filter component -- compare to the D3091 P100 filter for programs that run particulate-only tasks alongside multi-gas combination cartridge tasks on the same Secure Click facepiece fleet. For programs running extended particulate-only tasks, the D9093 P100 hard case filter may be more cost-effective for those task segments than running a D80926 for P100-only protection.

Final verdict -- 3M Secure Click D80926 Multi-Gas + P100 Combination Cartridge

Rating: 4.5 / 5

The 3M Secure Click D80926 earns 4.5/5 as the only Secure Click cartridge that covers the full multi-gas + P100 hazard profile: organic vapors, acid gases, ammonia, methylamine, formaldehyde, and integrated P100 particulate filtration in a single Secure Click housing, sold as a 1-pair pack. For the specific applications that require it -- wastewater spray, pesticide spray, formaldehyde spray environments, industrial refrigeration maintenance, and multi-hazard crews requiring a universal Secure Click combination cartridge -- the D80926 is the only correct answer in the Secure Click line. The deductions from 5/5: no isocyanate coverage (a universal limitation of all air-purifying cartridges, but critical to document); no CO coverage; highest cost per pair in the line; and the over-specification risk that makes it the wrong choice when the documented hazard profile does not include ammonia or formaldehyde (in which case the D80923 or D80921 is the correct and more cost-effective specification). When the hazard profile matches the D80926's coverage, no other Secure Click cartridge does what it does.

3M Secure Click D80926 -- 4.5 / 5
The maximum-coverage Secure Click combination cartridge -- OV + AG + NH3 + HCHO + P100 in one push-click installation. The correct specification when the documented hazard profile requires it; over-specified when it does not.

Frequently asked questions -- 3M Secure Click D80926

Is the 3M Secure Click D80926 the right cartridge for wastewater treatment spray operations?

Yes -- wastewater treatment facilities generate documented ammonia (NH3) exposure from aeration basins, digester operations, and sludge handling, often alongside organic chemical exposure and aerosol from spray equipment. The D80926's OV + acid gas + NH3 + CH3NH2 + HCHO + P100 profile covers the documented hazard mix at wastewater treatment spray operations. Confirm your site's air monitoring data for specific contaminants and concentrations, and use 3M's service life software to calculate change-out intervals for each documented chemical. Engineering controls (ventilation, process enclosure) remain the hierarchy-of-controls priority alongside cartridge selection.

What is the difference between the D80926 and the D80923?

The D80923 covers organic vapor, acid gases (Cl2, HCl, SO2, HF), and P100 particulate. The D80926 extends that coverage to also include ammonia (NH3), methylamine (CH3NH2), and formaldehyde (HCHO). If your hazard inventory includes ammonia or formaldehyde alongside OV and acid gas exposure, the D80926 is required. If it does not, the D80923 provides equivalent protection for your actual hazard profile at a lower per-pair cost. Do not default to the D80926 for every acid gas environment -- confirm your full hazard list through SDS review and air monitoring before specifying the broader cartridge.

What is the difference between the D80926 and the D80921?

The D80921 covers organic vapor and P100 particulate. The D80926 extends to additionally cover acid gases, ammonia, methylamine, and formaldehyde. The D80921 is the correct and lower-cost cartridge for OV + particulate environments with no acid gas, ammonia, or formaldehyde component -- spray painting, solvent-borne coatings, lacquer, adhesive spray. The D80926 is required only when the additional chemical classes are documented in the hazard assessment. See our D80921 review for the base comparison.

What is the difference between the D80926 and the D8006?

Both cover the full multi-gas profile: OV + acid gases + ammonia + methylamine + formaldehyde. The critical difference: the D80926 includes an integrated P100 particulate filter (99.97% efficient, oil-resistant); the D8006 includes no particulate filtration. Use the D8006 for multi-gas vapor exposure without spray aerosol or airborne particulate -- wipe-on, dip, or brush processes in multi-gas chemical environments. Use the D80926 when spray application or aerosol generation adds a particulate exposure component that requires P100 filtration alongside the multi-gas vapor coverage.

Can the D80926 be used on a 3M 6000 or 7000 series respirator?

No. The Secure Click push-and-click positive-lock mount is physically incompatible with the bayonet twist-and-lock port on 6000, 6500, 7000, 7500, and 7800S facepieces. The D80926 is compatible only with 3M HF-800 and FF-800 Secure Click facepieces. The equivalent cartridge for bayonet-system respirators is the 3M 60926 multi-gas combination cartridge.

What respirators is the 3M D80926 compatible with?

The D80926 fits all Secure Click facepieces: 3M HF-801 (small half-face, APF 10), 3M HF-802 (medium half-face, APF 10), 3M HF-803 (large half-face, APF 10), and 3M FF-800 (full-face, APF 50). One D80926 pair fits the entire Secure Click fleet. For chemical processing and wastewater environments where multi-gas concentrations may be elevated, the FF-800 full-face with D80926 at APF 50 is often the more appropriate platform than the half-face at APF 10.

Does the D80926 protect against isocyanates?

No. The D80926, like every air-purifying cartridge in the Secure Click line and the entire 3M cartridge catalog, provides no protection against isocyanate vapors (MDI, HDI, TDI, IPDI). If your chemical processing or coating application includes any isocyanate-containing material, a supplied-air respirator (SAR) per OSHA 29 CFR 1910.134 is required. The D80926's broad multi-gas coverage does not extend to this chemical class under any circumstances. Check every coating, adhesive, and chemical SDS for any diisocyanate or polyisocyanate listing.

Does the D80926 protect against carbon monoxide (CO)?

No. No activated carbon air-purifying cartridge protects against carbon monoxide. CO from combustion engines, generator exhaust, or chemical process combustion requires a SCBA, supplied-air respirator, or specialized CO-rated combination unit. In multi-gas environments where combustion equipment operates nearby, CO monitoring and engineering controls (ventilation, equipment exclusion zones) are required. The D80926 cannot be specified as CO protection under any circumstances.

What is the OSHA assigned protection factor for the D80926 on an HF-800?

Per OSHA Table 1 to 29 CFR 1910.134, half-face air-purifying respirators carry an APF of 10. The HF-800 with D80926 protects against multi-gas and P100 particulate contaminants at or below 10x the applicable OSHA PEL for each chemical. In environments where multi-gas concentrations (particularly ammonia or acid gases) may exceed 10x PEL, the 3M FF-800 full-face respirator with the same D80926 cartridge carries APF 50. Above 50x PEL for any contaminant, a supplied-air respirator is required regardless of cartridge coverage.

How often should I replace D80926 cartridges in a multi-gas environment?

OSHA 29 CFR 1910.134(d)(3)(iii)(B) requires a documented change-out schedule for all activated carbon cartridges without ESLI. In multi-gas environments, run 3M's Chemical Cartridge Service Life Estimation Software separately for each documented chemical contaminant: OV compounds, acid gases, ammonia, formaldehyde. Each calculation requires chemical identity, measured or estimated air concentration, relative humidity, and worker breathing rate. Apply the most conservative (shortest) calculated service life across all contaminants as the program's change-out interval. Never use odor as the signal -- several chemicals covered by the D80926, including formaldehyde and HF at regulated concentrations, may not produce reliable odor warning before breakthrough.

Does the D80926 have an ESLI?

No. The D80926 does not include an end-of-service-life indicator. This is consistent across the full Secure Click D-series cartridge line. OSHA mandates a documented change-out schedule per 29 CFR 1910.134(d)(3)(iii)(B) for all activated carbon cartridges without ESLI. For multi-gas environments, the service life calculation is more complex than for single-gas cartridges -- ensure all documented contaminants are included in the calculation and that the result is recorded in your written respiratory protection program.

Is the D80926 NIOSH-approved -- what is the TC number?

Yes. The 3M Secure Click D80926 carries a NIOSH combination cartridge approval under 42 CFR Part 84 Subpart L, TC-23C category covering the full multi-gas + P100 combination profile. The specific TC approval number for the D80926 can be verified on the NIOSH Certified Equipment List (CEL) under the TC-23C category for 3M. Record the TC number in your written respiratory protection program when specifying the D80926 as the program cartridge.

Is the D80926 adequate for pesticide spray applications?

For many commercial pesticide spray formulations involving organic solvent carriers, acid gas components, and ammonia-based active ingredients or adjuvants, the D80926's multi-gas + P100 profile addresses the documented chemical mix. Critical qualifications: (1) verify each active ingredient and carrier chemical on your pesticide SDS against the D80926's approved chemical list; (2) some pesticide active ingredients (organophosphates, pyrethroids) require verification that they fall within the organic vapor approval category; (3) EPA pesticide label requirements may specify respirator type and APF that must be met regardless of SDS-only analysis; (4) if the pesticide label specifies a full-face respirator, the FF-800 with D80926 (APF 50) is required rather than the HF-800 (APF 10).

Can the D80926 be used with the 3M FF-800 full-face respirator for higher APF?

Yes -- and for many D80926 applications (wastewater treatment, chemical processing, refrigeration maintenance), the FF-800 full-face at APF 50 is the more appropriate facepiece than the HF-800 half-face at APF 10. The FF-800 with D80926 provides full-face coverage against acid gas, ammonia, and aerosol splash alongside the elevated APF, which is relevant when multi-gas concentrations are variable or can transiently exceed 10x PEL. The D80926 cartridge is the same for both platforms -- the facepiece selection is driven by your air monitoring data and exposure assessment.

Is the D80926 sold as a 1-pair pack?

Yes. The 3M Secure Click D80926 is sold as a 1-pair pack -- the package includes two cartridges, one for the left port and one for the right port of the HF-800 or FF-800 facepiece. Both cartridges must be installed and replaced together as a pair. Never operate a dual-cartridge half-face or full-face respirator with one fresh and one used cartridge -- the total protection provided is limited by the most exhausted cartridge in the pair. Pair pricing is standard for all dual-cartridge Secure Click cartridges including the D80921, D80923, and D80926.

When does it make sense to specify the D80926 as a single-SKU program cartridge?

Specifying the D80926 as a program-wide single SKU makes operational sense when: (1) the crew's documented hazard range spans multiple chemical classes that collectively require the D80926's full multi-gas + P100 profile on at least some tasks; (2) the risk of field selection errors when workers choose between multiple cartridge SKUs during shift changes or task rotations is higher than the per-pair cost premium; and (3) the logistics cost of stocking, tracking, and distributing multiple cartridge SKUs exceeds the cost delta between the D80926 and narrower cartridges. This is a program-design decision that requires a full cost-benefit analysis -- the D80926's cost premium over the D80923 or D80921 is real, and the consolidation benefit only justifies it when the above conditions are met. Consult your Certified Industrial Hygienist (CIH) when designing multi-SKU versus single-SKU respiratory protection programs.

What is the Secure Click D80926's bayonet equivalent?

The 3M Secure Click D80926 is the functional equivalent of the 3M 60926 bayonet multi-gas combination cartridge: same protection profile (OV + AG + NH3 + CH3NH2 + HCHO + P100), different mount system. The D80926 uses the Secure Click positive-lock mount (HF-800 and FF-800 only); the 60926 uses the bayonet mount (6000, 7000, 6500, 7500, 7800S facepieces). They are not physically interchangeable. Workers migrating from a 60926-based program to the Secure Click platform should verify the HF-800 or FF-800 facepiece size and fit before deploying D80926 cartridges.

How does the D80926 handle formaldehyde exposure in spray environments?

Formaldehyde (HCHO) is specifically listed in the D80926's approved chemical coverage. In spray environments where formaldehyde is generated (anatomy specimen fixation spray, formaldehyde-based resin spray in composite manufacturing, or spray operations adjacent to freshly cut MDF releasing formaldehyde off-gas), the D80926's formaldehyde sorbent addresses the vapor-phase hazard while the integrated P100 addresses the aerosol particulate phase. Formaldehyde is regulated by OSHA under 29 CFR 1910.1048, which includes specific requirements for exposure monitoring, medical surveillance, and written exposure control plans that apply independently of cartridge selection. The D80926 satisfies the respiratory protection component of a compliant formaldehyde program for exposures within its APF range, but does not replace the other 1910.1048 requirements.
