Meet the CM-6M® Tactical Gas Mask—MIRA Safety®’s flagship protective mask and one of the most widely adopted full-face respirators in its class. Built with durable professional-grade materials and extensively tested, the CM-6M® is our top recommendation for emergency preparedness, personal safety, and professional hazard protection.
Its panoramic, impact-resistant visor provides a wide field of view for improved situational awareness, while the hypoallergenic inner mask reduces fogging and CO2 buildup to keep breathing comfortable during extended wear. An integrated hydration system, a highly intelligible speech diaphragm, and dual filter ports—allowing users to choose left- or right-side filter placement—make the CM-6M® adaptable to a wide range of operational needs.
The CM-6M® also integrates seamlessly with accessories like the MIRA Vision® Spectacle Kit and PROFILM® Visor Protectors (sold separately), enabling users to customize the mask to their specific environment or mission.
Trusted by police organizations worldwide and compliant with European safety standards, the CM-6M® delivers proven protection in high-risk environments where reliability matters most.

[H2] Roman’s Take
The CM-6M® is our best-selling gas mask—and for good reason. It was the first respirator we introduced back in 2018 when we launched MIRA Safety® and it’s been a cornerstone of our lineup ever since.
This rugged, general-purpose CBRN mask is built for professional-grade performance in real-world scenarios. It comes standard with an integrated hydration system (including a canteen) and a speech diaphragm for improved communication. It’s also compatible with a wide range of optional accessories—such as the MIRA Safety® microphone, VPU, tear-off visor protectors, and a spectacle kit for prescription eyewear—all sold separately.
The CM-6M® has been widely adopted by CBRN specialists around the world, as well as by law enforcement agencies for riot control. One standout feature is the durability of its visor. Unlike many competitors, the CM-6M®’s visor is highly impact resistant and tested to the EN 168 European standard. We’ve even gone a step further—firing a bean bag round from a Mossberg shotgun at the visor from just 15 feet away. The result? No cracks, no punctures, no failures. (Of course, results may vary depending on the projectile and distance—so try not to get hit.)
Another critical upgrade worth highlighting is the use of tear-off visor protectors. These aren’t just helpful for training—they’re essential in riot conditions. If your visor is hit with paint, debris, or chemical residue, visibility can be instantly compromised. And in high-stress environments like civil unrest, situational awareness is everything. Tear-offs—similar to those used in motocross—allow you to peel away a dirty layer and restore clear vision in seconds.
That’s why we often recommend the CM-6M® to customers in riot-prone areas, or to journalists covering civil unrest. It’s become a go-to choice for media professionals reporting from protests and conflict zones across the U.S. and abroad.
If the CM-6M® has one limitation, it’s cheek weld. Due to the shape of the visor, achieving a proper cheek weld with a rifle can be challenging. If you’re using optics, we recommend running a riser of at least 2 inches for better alignment and comfort.
The CM-6M® is manufactured in the Czech Republic, in the same facility as our CM-7M® and CM-8M® masks—ensuring consistent quality you can trust.

The CM-6M® Tactical Gas Mask protects against toxic industrial chemicals (TICs), particulates, organic vapors, chemical warfare agents, and CBRN contaminants when used with appropriate filters.
Dual filter ports allow users to select the most comfortable filter position for their task or equipment layout. The inner mask design improves extended-wear comfort by reducing CO2 buildup and preventing fogging, while the integrated speech diaphragm enhances communication clarity in mission-critical scenarios.
The CM-6M® is compatible with the MIRA Vision® Spectacle Kit for prescription eyewear. Filters may be mounted on either inhalation port, and unused ports must be sealed with the supplied plug to maintain protective integrity.
The mask requires an environment with at least 19.5% oxygen to operate safely and is approved for use in Class 1 explosive environments. It meets the highest full-face protection category under EN 136 (Class III), representing top-tier protection, durability, and resistance to harsh conditions.
Designed for a wide range of professional applications—including industry, agriculture, emergency response, law enforcement, welding, construction, and civil defense—the CM-6M® tactical gas mask is also a strong choice for general CBRN preparedness and everyday readiness planning.
[H2] Storage of CM-6M® Tactical Gas Mask
The CM-6M® full face tactical gas mask must be stored in a dark, cool, and dust-free area, free from sudden temperature changes. The storage room should be ventilated regularly. Temperatures may vary between 10 °C and 25 °C with relative humidity up to 65%. Full-face gas masks must not be exposed to radiant heat or sunshine. Fuels, solvents, lubricants, and other flammable substances, including chemicals, must not be stored with gas masks. Moreover, there must not

The MIRA Safety® HAZ-SUIT® is engineered as a professional-grade hazmat suit with a respirator included, designed for long-term CBRN and chemical protection in emergency response, industrial safety, and preparedness applications. Built from a durable multi-layer barrier laminate and tested against more than 125 chemical threats, it offers a reliable protective solution for both professionals and families seeking robust all-hazard readiness.
[H2] How Experts Evaluate the Best Hazmat Suit Fabrics
When professionals evaluate what separates an ordinary protective coverall from a true hazmat suit, the first thing they look at is the fabric. Not all military hazmat suit materials are engineered for the same threats, and understanding these differences is key to selecting gear that performs in real emergencies—not just on controlled job sites.
Our CBRN hazmat suit is specifically designed to protect the wearer against specific chemical categories, industrial splash, and more.
More advanced industrial suits use coated fabrics or single-layer laminates, which offer better splash resistance but are often designed for specific chemical categories—not the broad-spectrum threats involved in CBRN events.
High-performance hazmat suits—those used by emergency response teams, military units, and CBRN specialists—are built from multi-layer barrier laminates engineered to:
Resist chemical permeation
Block a wide range of liquids and vapors
Built to reduce the likelihood of punctures and abrasions
Maintain flexibility under extended wear or movement
The HAZ-SUIT® fabric falls into this professional and military category. Its multi-layer composite has been extensively tested against more than 125 chemical threats, including toxic industrial chemicals (TICs) and chemical warfare agents (CWAs). Long-term aging studies show that the barrier retains its performance for decades when stored correctly.
Combined with heat-sealed/taped seams, the HAZ-SUIT® forms a unified barrier system suited for unpredictable, high-stress environments.
[H2] Hazmat Suit Use Cases and Emergency Response Applications
This reusable hazmat suit is used extensively by:
Major fire departments for hazmat response
Large hospitals for emergency preparedness
Industrial and petrochemical companies
Multiple branches of the U.S. military and other government agencies
Emergency medical responders, industrial safety teams, and preparedness-minded civilians rely on this protective suit when working in hazardous environments.
Our military-grade hazmat suit has undergone long-term storage testing under various environmental conditions. When stored in a cool, dry location away from sunlight, it demonstrates no measurable degradation—even after decades—making it a strong option for long-term preparedness and emergency planning.
[H2] CBRN Protection Level and Suit Performance
The MIRA Safety® HAZ-SUIT® is designed for hazardous applications involving chemical splashes, particulates, and vapor exposure. Its multi-layer barrier laminate, abrasion resistance, and broad-spectrum chemical testing provide durability and reliability for environments where low-cost disposable suits are inadequate.
Radiological protection (at a glance): The HAZ-SUIT® helps protect against radioactive particulates by preventing alpha-emitting dust and many beta contaminants from contacting the skin or clothing. Like all suits in its class, it does not shield against penetrating gamma or neutron radiation; radiological safety in such scenarios depends on time, distance, shielding, and proper respiratory protection to prevent inhaling radioactive particulates.
[H2] Key Features of the MIRA Safety® Hazmat Suit (HAZ-SUIT®)
Complete protection for all ages: Available in youth and adult sizes to provide personal protection for children as young as 4 years old through large adults.
Professional-grade CBRN defense: Designed for civil defense, emergency response, and hazardous environments requiring true CBRN resistance—not just light-duty splash protection.
Trusted by professionals worldwide: Used by military units, fire departments, hospitals, and industrial hazmat teams globally.
Extended practical shelf life: Long-term aging tests show its multi-layer barrier fabric maintains performance for decades when properly stored.
NFPA-certified options: Certain configurations are available for bulk orders requiring specialized certification.
Made in the USA: Manufactured in partnership with Kappler, a U.S. leader in chemical protective apparel.
Proven chemical protection: Tested and proven against a wide range of CWAs and TICs.
Enhanced durability: High tensile and puncture resistance help protect against hazards in debris-filled or unpredictable environments.
Advanced seam sealing: Heat-sealed and taped seams create a consistent, reliable barrier.
Universal compatibility: Integrates with MIRA Safety gas masks, full-face respirators, gloves, boots, and chemtape for a complete protective ensemble.
Typical applications: Civil defense, emergency response, military operations, drug-lab response, chemical handling, petrochemical maintenance, pandemic readiness, and toxic waste or contaminated site cleanup.
[H2] HAZ-SUIT®: A Trusted Solution for Serious Hazmat and CBRN Protection
Many protective coveralls are designed for controlled industrial tasks where exposure is predictable and short-term. The HAZ-SUIT® addresses a different need: unpredictable events, extended exposure windows, and the possibility of encountering some of the most dangerous modern threats.
Its puncture-resistant, multi-layer barrier laminate is similar to the materials used in high-end CBRN suits globally. When worn with a PAPR or air-purifying respirator, the HAZ-SUIT® functions as a Level C hazmat suit. When paired with an SCBA, it can be used as part of a Level B ensemble.
The suit is engineered for up to eight hours of direct exposure to numerous chemical agents and radioactive particulates listed in standardized tests. With proper respiratory protection, gloves, boots, and chemtape, it forms a complete system suitable for a wide range of hazardous environments.
When stored correctly, it remains ready for use for decades, offering a long-term preparedness advantage.

[H2] Shelf Life on HAZ-SUIT® Chemical Garments
How long do hazmat-suits last? The HAZ-SUIT® can last up to twenty years. A coverall using the twenty-year-old HAZ-SUIT® fabric was tested against the ASTM F1001 list of twenty-one chemicals with no breakthrough in >480 minutes.
The aged fabric was also tested for its physical properties and still meets manufacturing specifications. Based on this information, MIRA Safety considers the shelf life of its HAZ-SUIT® products to be undetermined.
Chemical suits contain components made from various polymer or rubber materials for which there is no shelf life data available. Therefore, the garments may be used as long as they are deemed safe after a visual inspection and, in the case of vapor protective (Level A) garments, after passing the ASTM F1052 pressure test. It is recommended that suits are downgraded to training use only when they no longer pass visual inspection and/or pressure testing.
It is the wearer's responsibility to ensure that all components, including fabric, valves, visors, gloves, zippers, seams, and suit-to-component interfaces, are in good working condition and provide adequate protection for the conditions and chemicals to be encountered. Any suit that does not pass the visual and/or pressure test should be immediately removed from service.

Summary

Protects against CBRN threats, riot control agents, toxic industrial chemicals, and radioactive methyl iodide.

Protects against toxic chemicals and converts CO to CO2, but not for full CBRN protection.

The lightweight NBC-77 SOF offers similar protection at lower concentrations, enhancing mobility without compromising safety.

Removes riot control agents with higher absorption than the P-CAN Compact.

The compact P-CAN efficiently filters riot control gases with significant weight and size savings.

Our compact particle filter variant features a slightly smaller surface area, resulting in faster saturation compared to the standard size P3 filter.

The NBC-77 SOF® is our flagship 40mm gas mask filter, designed to provide comprehensive respiratory protection against a wide range of chemical, biological, radiological, and nuclear threats. When combined with a compatible full-face gas mask or PAPR, this NATO-standard filter helps protect your airways from all known CBRN agents, toxic industrial chemicals, radioactive iodine, organic iodine compounds, and hazardous particulates.
The NBC-77 SOF® uses a standard Rd 40 × 1/7" thread in accordance with STANAG 4155 (EN 148-1), making it compatible with most modern 40mm gas mask filter platforms. Its rugged hard-plastic housing is engineered to withstand shock and impact in operational use, helping to protect the filtration media and preserve performance in the field.
[H2] New Color Options for the ®40mm Gas Mask Filter
We’re excited to introduce two new color options for the NBC-77 SOF® 40mm gas mask filter canister, giving you more flexibility to match your equipment to your environment:
Ranger Green: A versatile, muted green shade that blends well into woodland and mixed terrain environments. This color option provides excellent camouflage for tactical and field applications where visual signature matters.
Sandstone: A neutral, earth-toned color ideal for desert, arid, and rocky terrains. This option offers effective concealment in bright, sandy, or stone-dominated environments.
These new finishes join the existing lineup, providing even more versatility for a variety of operational needs. Whether you’re operating in dense forests, arid deserts, or urban environments, there’s now an NBC-77 SOF® gas mask filter color to match your requirements, without any difference in performance or specifications.
[H2]
Roman’s Take on the NBC-77 SOF® Gas Mask Filter
The NBC-77 SOF® is my go-to recommendation for anyone who wants a single filter that truly does it all. What makes it stand out is that it combines three major filtration capabilities: classic CBRN protection, coverage for toxic industrial chemicals, and DIN-rated reactor performance into one cartridge.
Typically, agencies would stock separate filters for CBRN agents, industrial gases, and radioactive iodine compounds like methyl iodide. With the NBC-77 SOF®, you get all of that in one package. It’s rated for all known CBRN agents, covers a very wide range of TICs, and is one of the few consumer-accessible filters that’s actually tested and rated as a Reactor filter, meaning it can filter radioactive methyl iodide gas.
The second big advantage is shelf life. At 20 years, this filter outlasts most competitors by a factor of two or three. A lot of CBRN filters have a 5–7 year shelf life, which means you’d replace them multiple times over the life of a single NBC-77 SOF®. When you look at the cost of ownership per year, this filter ends up being one of the most economical options out there, while still offering some of the broadest protection you can get.
From a preparedness standpoint, that combination is rare. You get long shelf life, real CBRN capability, strong coverage against toxic industrial chemicals, and nuclear-reactor-grade filtration in one unit. If you’re looking for a “one-and-done” filter to keep on hand for serious emergencies, this is the one I point people to.
[H2] Key Features of This NATO Gas Mask Filter
Compatible with standard 40mm NATO threaded respirators (Rd 40 × 1/7"), which are widely available and used around the world.
20-year shelf life when factory sealed, helping you save money over time by reducing the need to replace filters every 5–7 years.
Used by military personnel, CBRN specialists, and special operations forces worldwide, providing proven performance in real-world conditions.
Filters all known CBRN agents, including radioactive iodine, and is rated A2B2E2K2HgSXP3 D R REACTOR under EN 14387.
Certified by European agencies and marked with the “CE” symbol. Compliant with EN 14387:2004 + A1:2008.

Service Life of the NBC-77 SOF® Gas Mask Filter
Breakthrough time of a gas mask filter is tested according to EN 14387+A1 at 70% relative humidity and a flow rate of 30 l/min, which is equivalent to the volume of air per minute used by an average person carrying out medium-heavy work. The approximate lifetime (usage time) of the NBC-77 SOF® filter may, under normal conditions, be estimated by comparing the concentration at the workplace with the minimum Dynamic Adsorption Capacity (DAC) specified for the filter.
[H2] Gas Mask Filter Storage and Maintenance
Each NBC-77 SOF® gas mask filter is sealed in a plastic bag by the manufacturer. Store the filters unopened in a clean place at a sta
