MSA Safety Respirators: Complete Buyer's Guide (2026)

MSA Safety Respirators: Complete Buyer's Guide (2026)

If you manage a workforce exposed to chemical vapors, acid gases, particulates, or combined hazards, selecting the right air-purifying respirator is one of the most consequential PPE decisions you will make. MSA Safety — founded in 1914 and still one of the most cited brands in industrial hygiene literature — produces a focused, NIOSH-approved respirator lineup that spans from budget half-masks to premium full-face units capable of protecting against IDLH-adjacent concentrations. This guide covers every MSA elastomeric respirator currently sold through WC Safety, decodes the Advantage and Comfo Classic product families, maps the GM-series cartridge ecosystem, and walks you through the OSHA 29 CFR 1910.134 selection and compliance requirements your program must satisfy before a single respirator goes on a worker's face.

Unlike disposable filtering facepieces, MSA's elastomeric respirators are reusable platforms. The facepiece itself is a long-term asset; cartridges and filters are consumables replaced on a defined change-out schedule. That model shifts the total cost of ownership calculus significantly — a $25 Advantage 200 LS used with a $12 cartridge pair and replaced at six-month intervals is far cheaper over a three-year program than an equivalent run of N95 disposables for daily chemical exposure. But the platform approach also demands that buyers understand cartridge compatibility, fit testing obligations, and the difference between half-mask APF 10 protection and full-face APF 50 protection before committing to a program.

This guide is written for industrial hygienists, EHS managers, procurement leads, and safety supervisors selecting MSA respirators for OSHA 1910.134 respiratory protection programs. We cover the half-mask lineup — MSA Advantage 200 LS, MSA Advantage 420, MSA Advantage 900, and MSA Comfo Classic — and the full-face lineup: MSA Advantage 3200, MSA Advantage 4100, MSA Advantage 1000, and the MSA Ultra Elite. Where relevant we note cartridge decode tables, competitive positioning against 3M and Honeywell North, and verified links to WC Safety's collection pages and review articles.

For sourcing, start with our curated collections: MSA Half-Mask Respirators and MSA Full-Face Respirators.

MSA Respirator Lineup Overview

MSA organizes its air-purifying respirator portfolio around two platform families: the Advantage series and the Comfo Classic series. Each family shares a cartridge threading system within its own line but the two systems are not cross-compatible — Advantage cartridges do not fit Comfo Classic facepieces and vice versa. Understanding which family you are buying into before committing to a multi-respirator program is critical, since cartridge costs and availability differ between platforms.

The Advantage Series

The Advantage family uses MSA's proprietary low-profile bayonet mount, which accepts the GM-series cartridges with the "A" prefix (GMA, GMA-P100, GMAC, and so on — detailed in the cartridge decode section below). The design priority in the Advantage line is economy of scale: the facepieces are engineered for cost-sensitive industrial programs that need NIOSH certification, reliable sealing geometry, and a deep cartridge catalog without paying a premium for specialty materials. Half-mask Advantage models range from the polypropylene Advantage 200 LS at around $24 to the silicone Advantage 420 and Advantage 900. Full-face Advantage models — the 3200, 4100, and 1000 — provide the same APF 50 protection at price points well below MSA's flagship Ultra Elite.

The Comfo Classic Series

The MSA Comfo Classic is MSA's legacy platform, dating to decades of use in chemical and pharmaceutical facilities. The Comfo Classic uses the "C" prefix GM-series cartridges (GMC, GMC-P100, GMCH, etc.) and is constructed from medical-grade silicone with a wider seal flange than the Advantage half-masks. Workers who spend extended shifts in respirators — painters, chemical operators, pharmaceutical manufacturing — often report better facial seating with the Comfo Classic due to its softer, more conforming silicone. The trade-off is a higher unit price ($68–$71 vs $24–$63 for comparable Advantage half-masks) and a cartridge ecosystem that runs parallel to, but separate from, the Advantage line.

The Ultra Elite

The MSA Ultra Elite occupies its own tier as MSA's premier full-face respirator. It features a panoramic polycarbonate lens, internal nosecup for lens clarity in high-humidity environments, and a six-point adjustable harness. The Ultra Elite is rated for CBRN (chemical, biological, radiological, nuclear) applications in certified configurations and is the respirator MSA markets to hazmat teams, industrial emergency response, and shipyard/aerospace facilities requiring the highest level of face seal integrity available in an air-purifying design.

Half-Mask Respirators (APF 10)

Half-mask air-purifying respirators carry an Assigned Protection Factor of 10 under OSHA's APF table (OSHA 29 CFR 1910.134), meaning they may be used when airborne concentrations do not exceed 10 times the permissible exposure limit (PEL) or threshold limit value (TLV). They cover the nose and mouth but not the eyes, so they are not appropriate for ocular hazards. All four MSA half-masks in WC Safety's lineup are NIOSH-approved and accept MSA's interchangeable cartridge systems.

MSA Advantage 200 LS — Entry-Level Workhorse

At $24.38, the MSA Advantage 200 LS is the lowest-cost NIOSH-approved elastomeric half-mask in the lineup. The "LS" designation indicates a low-silhouette bayonet mount that keeps cartridges closer to the face and reduces torque on the facepiece — a significant ergonomic advantage in confined-space, scaffold, or overhead work where protruding cartridges create snagging hazards. The facepiece material is polypropylene rather than silicone, which makes it suitable for programs with high worker turnover or environments where disposability of the facepiece between assignments is a priority. Read the full MSA Advantage 200 LS review for detailed fit and field performance data.

MSA Advantage 420 — Mid-Range Silicone

The MSA Advantage 420 steps up to silicone construction at $50.61, providing a softer, more durable facepiece that withstands repeated disinfection cycles and extended daily wear without cracking or taking a compression set. The Advantage 420 uses the same bayonet cartridge mount as the 200 LS, so programs can mix facepiece models while maintaining a single cartridge inventory — a meaningful logistics simplification. The 420 is well-suited to applications requiring daily use or where multiple workers share cartridge stock. See the MSA Advantage 420 review for field data and sizing notes.

MSA Advantage 900 — Snap-On for Fast Changes

The MSA Advantage 900 at $62.91 introduces a snap-on cartridge attachment that locks and releases cartridges faster than the bayonet system — a meaningful feature in operations where cartridges are changed multiple times per shift or where heavy gloves make fine-motor bayonet manipulation difficult. The silicone facepiece is identical in seal geometry to the Advantage 420, so workers familiar with the 420 will find the fit equivalent. The snap-on mechanism does use a different cartridge adapter, so confirm compatibility with your existing GM-series inventory before deploying. Full field notes in the MSA Advantage 900 review.

MSA Comfo Classic — Legacy Comfort Leader

Priced at $68.78–$70.71 depending on size, the MSA Comfo Classic uses a wide-seal flange in medical-grade silicone that has been refined over decades of use in pharmaceutical and chemical operations. Workers wearing the Comfo Classic for full eight-hour shifts in painting, laboratory, or chemical-processing environments consistently cite lower facial fatigue than with narrower-flange designs. It accepts the GMC-series cartridges rather than the GMA-series used by Advantage half-masks — plan your cartridge inventory accordingly. The MSA Comfo Classic review covers sizing variance and cartridge sourcing in detail.

To compare Comfo Classic vs Advantage feature-by-feature, see the MSA Comfo Classic vs Advantage comparison guide. For our curated picks across the half-mask lineup, see Best MSA Half-Mask Respirators (2026).

Half-Mask Comparison Table

Full-Face Respirators (APF 50)

Full-face air-purifying respirators carry an Assigned Protection Factor of 50 under OSHA 1910.134, covering the eyes, nose, and mouth against airborne hazards up to 50 times the PEL/TLV. They are the correct choice when half-mask APF 10 protection is insufficient — typically at concentrations between 10× and 50× the PEL, or whenever ocular protection from vapors, gases, or mists is required simultaneously. All MSA full-face models accept the GMA-series (Advantage line) or corresponding full-face cartridges. Fit testing is mandatory before first use.

MSA Advantage 3200 — Hypoallergenic Silicone Platform

At $269.29, the MSA Advantage 3200 is MSA's mid-tier full-face respirator, rated 4.6/5 by WC Safety editorial testers. The Advantage 3200 uses a hypoallergenic silicone facepiece with a wide-view polycarbonate lens and a five-point adjustable harness. Its twin-port cartridge design provides balanced airflow and allows the use of standard GMA-series cartridges, simplifying procurement for facilities already running Advantage half-masks. The Advantage 3200 is NIOSH-approved for combination cartridge configurations covering organic vapors, acid gases, and P100 particulate. Full testing notes in the MSA Advantage 3200 review.

MSA Advantage 4100 — Single Port with Nosecup

The MSA Advantage 4100 adds an internal nosecup — a secondary seal over the nose bridge that isolates the lens cavity from exhaled breath. This design virtually eliminates lens fogging in high-humidity environments: painting booths, industrial laundries, humid underground utilities work, and confined vessel entry where temperature gradients cause rapid condensation. The single-port configuration accepts a single combination cartridge rather than twin ports. The nosecup also functions as a secondary seal, which can marginally improve fit factor in quantitative fit testing. See the MSA Advantage 4100 review for fogging and fit factor data.

MSA Advantage 1000 — Hycar Twin Port

The MSA Advantage 1000 uses Hycar (a nitrile-based elastomer) rather than silicone for its facepiece. Hycar offers superior chemical resistance against solvents, petroleum distillates, and chlorinated compounds that can degrade silicone over prolonged exposure — a meaningful consideration for chemical plant turnaround work, solvent vapor environments, and applications involving hydrocarbon splash. The twin-port design uses standard GMA-series cartridges. The Advantage 1000 occupies a chemical-resistance niche that the silicone Advantage 3200 and 4100 do not fill. Competitive positioning against similar designs is covered in the 3M 6500 vs MSA Advantage 1000 comparison and the Honeywell North 5500 vs MSA Advantage 1000 guide. Full performance notes in the MSA Advantage 1000 review.

MSA Ultra Elite — Flagship Full-Face

At $367.90, the MSA Ultra Elite is MSA's highest-tier air-purifying full-face respirator and the WC Safety editorial top pick, rated 4.8/5. The Ultra Elite's panoramic wrap-around polycarbonate lens provides a field of view that substantially exceeds that of rectangular-lens full-face designs — a critical operational factor for workers performing intricate tasks, inspecting pipework, or navigating material-handling equipment while donned. The six-point harness distributes weight across a broader headform, reducing pressure-point fatigue over extended wear periods. The Ultra Elite is also available in NIOSH-certified CBRN configurations for emergency response applications, though the standard industrial version reviewed here is the appropriate selection for routine 1910.134 programs. The 3M 7800S vs MSA Ultra Elite comparison guide provides a direct head-to-head for buyers choosing between MSA's and 3M's flagship full-face models. Full field testing in the MSA Ultra Elite review.

Full-Face Comparison Table

Cartridges & Filters — GM-Series Decode

MSA's cartridge naming convention follows a consistent GM-series code where the letter after "GM" identifies the series (A for Advantage half-mask/full-face, C for Comfo Classic) and the trailing letters identify the hazard class. All cartridges sold through WC Safety's MSA Respirator Filters and Cartridges collection are NIOSH-approved per 42 CFR Part 84. The table below decodes the GM-series codes for the Advantage and Comfo Classic families.

For cartridge-level comparisons against 3M equivalents — the most common cross-brand purchasing decision — see MSA GMA-P100 vs 3M 60921, MSA GMC-P100 vs 3M 60923, MSA GME-P100 vs 3M 60926, and MSA GMA vs 3M 6001. For cartridge change-out methodology, including the OSHA-required end-of-service-life indicator (ESLI) or schedule-based change-out approach, see our Cartridge Change-Out Schedule Guide.

Critical note on cartridge cross-compatibility: MSA Advantage cartridges (GMA/GMB/GMAC series) are not interchangeable with Comfo Classic cartridges (GMC/GMCH series) even though both use a similar bayonet-style fitting. The thread pitch and locking geometry differ between families. Never attempt to fit a GMA cartridge to a Comfo Classic facepiece or vice versa — improper seating will fail the user check and may not be detected without a fit test.

OSHA Selection & Compliance

OSHA 29 CFR 1910.134 imposes a structured written respiratory protection program on any employer who requires the use of air-purifying respirators. The American Industrial Hygiene Association's (AIHA) The Occupational Environment: Its Evaluation, Control, and Management (3rd ed.) identifies respirator selection as a risk-based engineering control decision, not a procurement exercise — the AIHA framework reinforces that cartridge selection must follow documented hazard evaluation, not brand preference or cost minimization alone. The following elements are mandatory under 1910.134 and directly relevant to MSA respirator deployment.

Cartridge Selection by Hazard Class

Under 1910.134(d)(1)(iii), the employer must select a NIOSH-approved respirator based on the contaminant(s) present, their airborne concentration, and the required protection factor. For organic vapor hazards below the APF 10 level, the Advantage 200 LS with a GMA cartridge is sufficient. For concentrations between 10× and 50× the PEL, a full-face respirator such as the Advantage 3200 with a GMA-P100 cartridge provides APF 50. For acid gas hazards, GMB (Advantage) or the corresponding GMCH combination cartridge (Comfo Classic) applies. Consult your industrial hygienist and the NIOSH Pocket Guide to Chemical Hazards for specific contaminant assignments.

Fit Testing Requirements

Section 1910.134(f) mandates that all tight-fitting respirators — which includes every MSA elastomeric model listed in this guide — be fit tested before initial use, whenever a different respirator facepiece is used, and at least annually thereafter. MSA elastomeric respirators may be fit tested using either qualitative (QLFT) or quantitative (QNFT) methods approved under 1910.134 Appendix A. Full-face respirators used at APF 50 must be quantitatively fit tested when used above a hazard concentration of 1,000× the IDLH in supplied-air mode, though in standard APF 50 air-purifying use, QLFT is permissible. For a complete protocol walkthrough, see our Respirator Fit Testing Guide.

Cartridge Change-Out Schedule

Under 1910.134(d)(3)(iii)(B)(1), employers must replace cartridges before end of service life. Unless the cartridge has an NIOSH-approved end-of-service-life indicator (ESLI), the employer must implement a change-out schedule based on objective information — contaminant breakthrough modeling, cartridge supplier data, or industrial hygiene air monitoring. MSA does not universally provide ESLIs on its GM-series organic vapor cartridges, so most programs using MSA cartridges in OV or OV/AG service will require a schedule-based approach. Our Cartridge Change-Out Schedule Guide covers the OSHA-compliant methodologies in detail.

Medical Evaluation

Before any worker is fit tested or required to wear an air-purifying respirator, OSHA 1910.134(e) requires a medical evaluation performed by a licensed health care professional using, at minimum, the questions in Appendix C. Conditions that may preclude elastomeric respirator use include significant cardiovascular disease, reduced pulmonary function, and claustrophobia. The medical evaluation must be completed before fit testing and repeated when an employee reports symptoms that may affect respirator use.

MSA vs 3M vs Honeywell North

MSA, 3M, and Honeywell North are the three dominant brands in the U.S. industrial elastomeric respirator market. Each has meaningful differences in cartridge ecosystem breadth, facepiece material options, and availability across distributor networks. The table below covers the head-to-head factors most relevant to OSHA 1910.134 program selection.

For head-to-head full-face comparisons, see the 3M 7800S vs MSA Ultra Elite, 3M 6500 vs MSA Advantage 1000, and Honeywell North 5500 vs MSA Advantage 1000 guides.

Frequently Asked Questions

What respirator does MSA make?

MSA Safety produces a focused lineup of NIOSH-approved air-purifying elastomeric respirators in two families: the Advantage series (half-masks: 200 LS, 420, 900; full-face: 3200, 4100, 1000) and the Comfo Classic series (half-mask only), plus the flagship Ultra Elite full-face respirator. MSA also produces supplied-air and self-contained breathing apparatus (SCBA) — notably the MSA G1 SCBA used by fire departments — but the elastomeric air-purifying lineup covered in this guide is the segment most relevant to OSHA 1910.134 industrial programs. MSA does not produce disposable filtering facepieces (N95s) as a primary product line.

Is MSA a good brand for respirators?

Yes. MSA Safety is one of the oldest and most established industrial safety brands in the United States, founded in 1914, and its respirator products are NIOSH-approved under 42 CFR Part 84 — the same federal standard that governs 3M and Honeywell North products. MSA respirators are widely used in mining, chemical processing, pharmaceutical manufacturing, petrochemical refining, and construction. The brand's reputation is strongest in full-face and SCBA categories, where the Ultra Elite and G1 are considered premium references. Half-mask Advantage models offer a competitive value proposition against 3M's 6000 series at similar price points.

What is the difference between MSA Advantage and Comfo Classic?

The Advantage and Comfo Classic are two separate facepiece platforms with incompatible cartridge systems. Key differences: (1) Cartridge mount — Advantage uses the GMA-series bayonet/snap-on mount; Comfo Classic uses the GMC-series threaded mount. (2) Facepiece material — Advantage half-masks range from polypropylene (200 LS) to silicone (420/900); Comfo Classic uses medical-grade silicone with a wider seal flange. (3) Price — Comfo Classic runs $68–$71 vs $24–$63 for Advantage half-masks. (4) Platform availability — Comfo Classic is half-mask only; the Advantage line spans both half-mask and full-face. For buyers choosing between the two, the MSA Comfo Classic vs Advantage comparison guide covers the decision criteria in detail.

What cartridges fit MSA Advantage respirators?

MSA Advantage half-masks (200 LS, 420, 900) accept the GMA-series cartridges: GMA (organic vapor), GMA-P100 (OV + P100 particulate), GMB (acid gas), GMAC (OV/acid gas combination), and others. MSA Advantage full-face models (3200, 4100, 1000) accept full-face rated versions of the same GMA-series. The Advantage 900 uses a snap-on mechanism that may require a specific adapter — verify before purchasing. Comfo Classic cartridges (GMC-series) are not compatible with Advantage facepieces. Browse the full range at the MSA Respirator Filters and Cartridges collection.

When should I use a full-face MSA respirator instead of a half-mask?

Use a full-face respirator (Advantage 3200, Advantage 1000, or Ultra Elite) when: (1) airborne concentrations exceed 10× the PEL/TLV, requiring APF 50; (2) the hazard includes vapors, gases, or mists that cause ocular irritation or damage; (3) the written respiratory protection program specifies full-face for specific job tasks; or (4) the industrial hygienist's exposure assessment indicates full-face as the minimum required protection. Half-masks (APF 10) are appropriate only when concentrations are confirmed to be below 10× the PEL.

Are MSA respirators NIOSH-approved?

Yes. All MSA elastomeric respirators sold through WC Safety — including every half-mask Advantage model, the Comfo Classic, all full-face Advantage models, and the Ultra Elite — carry NIOSH approval under 42 CFR Part 84. NIOSH certification means the respirator and its approved cartridge combinations have been independently tested and certified to achieve the stated protection levels when properly fitted and worn. The NIOSH approval number is printed on the facepiece. OSHA 1910.134(d)(1)(i) requires that only NIOSH-approved respirators be used in the workplace.

Do MSA respirators need to be fit tested?

Yes. All tight-fitting MSA elastomeric respirators — half-mask and full-face — require fit testing before initial use under OSHA 1910.134(f). Fit testing must be repeated annually and any time a different size or model facepiece is used, or when physical changes to the worker's face (significant weight change, dental work, facial surgery) may affect the fit. Both qualitative (QLFT) and quantitative (QNFT) methods are permissible for half-masks; full-face respirators may also be tested with either method. See our Respirator Fit Testing Guide for protocol details and method selection.

What is the difference between the MSA Ultra Elite and the Advantage 3200?

Both are full-face respirators with APF 50 and NIOSH approval, but they differ significantly in design and application. The Ultra Elite ($367.90) features a panoramic wrap-around lens for wider field of view, a six-point adjustable harness, an internal nosecup for anti-fogging, and is available in CBRN-certified configurations for emergency response. The Advantage 3200 ($269.29) uses a standard rectangular polycarbonate lens, a five-point harness, and is suited to routine industrial OSHA 1910.134 programs where the enhanced features of the Ultra Elite are not required. For most plant maintenance and chemical processing applications, the Advantage 3200 provides equivalent respiratory protection at ~27% lower cost.

What sizes do MSA Advantage respirators come in?

All MSA Advantage half-masks (200 LS, 420, 900) and the Comfo Classic are available in small, medium, and large. MSA full-face models (Advantage 3200, 4100, 1000, Ultra Elite) are also available in small, medium, and large in most configurations. Fit testing is required regardless of size selected — the "medium fits most" generalization is not a substitute for a documented fit test result. If a worker fails a medium fit test with one MSA model, try an adjacent size or a different facepiece geometry (e.g., Comfo Classic vs Advantage) before switching brands.

How often do MSA cartridges need to be changed?

Unless the cartridge has an NIOSH-approved end-of-service-life indicator (ESLI) that signals breakthrough, MSA organic vapor cartridges must be replaced on a schedule established by the employer based on objective information. The OSHA-compliant approach is to use the MSA or AIHA-published cartridge service life estimation method — which factors in contaminant type, concentration, humidity, temperature, and breathing rate — to determine a maximum service interval, then replace cartridges before that interval expires. A common conservative default in light industrial OV use is a single shift or eight hours, but this is not universally applicable. See the Cartridge Change-Out Schedule Guide for a worked methodology.

Is the MSA Advantage 1000 better than the Advantage 3200 for solvent environments?

For environments with heavy solvent vapor exposure or potential liquid splash of petroleum distillates, chlorinated solvents, or hydrocarbon compounds, the Advantage 1000's Hycar facepiece is superior to the silicone Advantage 3200. Hycar (nitrile-based elastomer) resists degradation from these chemical classes far better than silicone, which can swell, crack, or lose seal integrity after repeated contact. If the exposure is airborne vapor only with no liquid splash, either facepiece material provides equivalent protection — the Advantage 3200 at $269.29 may be the better value. If there is any risk of liquid contact, the Advantage 1000 is the correct selection.

What is the difference between MSA GMA and GMC cartridges?

GMA cartridges are designed for the Advantage series facepieces (200 LS, 420, 900, and the Advantage full-face models). GMC cartridges are designed for the Comfo Classic facepiece. The cartridge bodies use different mounting systems and are not interchangeable between platforms. Within each family, the hazard coverage designation follows a consistent suffix system: no suffix = OV only; B = acid gas; AC = OV/acid gas combination; P100 suffix = particulate filter added. See the GM-Series Decode table above for the full breakdown, or browse available cartridges at MSA Respirator Filters and Cartridges.

Is MSA or 3M better for industrial respirators?

Both are NIOSH-approved, field-proven platforms with strong industrial track records. 3M's advantage is cartridge breadth — the 6000-series cartridge catalog covers more specialized hazard classes than MSA's GM-series. MSA's advantages include the Hycar full-face option (Advantage 1000) for solvent splash environments, the panoramic Ultra Elite for CBRN/emergency response, and a strong reputation in mining and heavy industrial sectors. In routine OV and OV/P100 applications at APF 10 or APF 50, the two brands are functionally equivalent if properly fit tested. Program cost, cartridge availability through your distributor, and worker facial geometry (which determines which brand passes fit testing for your workforce) are the deciding factors. See MSA GMA-P100 vs 3M 60921 for a cartridge-level comparison.

What is the MSA Advantage 4100 nosecup for?

The internal nosecup in the Advantage 4100 creates a secondary seal over the nose and upper lip, isolating the lens cavity from warm exhaled breath. This dramatically reduces lens fogging — the primary operational complaint with full-face respirators in humid, hot, or variable-temperature environments. If workers in your application report fogging as a frequent problem with other full-face models, the Advantage 4100 is the targeted solution within the MSA lineup. The nosecup also provides a marginal improvement in face-seal integrity in some face shapes, which may be reflected in higher fit factors during quantitative fit testing.

What do I need to set up a respiratory protection program using MSA respirators?

Under OSHA 1910.134, a compliant written respiratory protection program using MSA respirators requires: (1) a written program designating a program administrator; (2) a hazard exposure assessment performed by or under the direction of a qualified industrial hygienist to quantify airborne contaminant concentrations and identify hazard classes; (3) respirator selection — choose the appropriate MSA model (half-mask vs full-face) and GM-series cartridge based on the hazard assessment and required APF; (4) a medical evaluation by a licensed health care professional before any worker is fit tested; (5) fit testing of the selected facepiece before initial use and annually thereafter; (6) a documented cartridge change-out schedule or ESLI program; and (7) a training program covering donning/doffing, seal checks, cartridge limitations, and maintenance. See our OSHA 1910.134 reference article for full program requirements.

Is the MSA Ultra Elite approved for CBRN hazards?

The MSA Ultra Elite is available in CBRN-certified configurations, but the standard industrial version sold for OSHA 1910.134 compliance is not the same assembly as the CBRN-certified version. CBRN certification under NIOSH requires specific cartridge assemblies tested against a defined set of chemical warfare agents and must be used together with the CBRN-certified facepiece assembly. For emergency response teams requiring CBRN certification, verify that the specific Ultra Elite assembly and cartridge combination carries the NIOSH CBRN approval number before procurement. For standard industrial hazards — organic vapors, acid gases, particulates — the industrial Ultra Elite with standard GMA-series cartridges provides APF 50 protection fully compliant with OSHA 1910.134.
