The MIRA Safety P-CAN police gas mask filter is one of the world’s most advanced solutions for potential long-term exposure to riot control gasses including CS, CN, and OC. 

Featuring the same basic characteristics as other MIRA Safety filters, these hydrophobic P3 police gas mask filters have almost 3 times as much activated carbon as competing filters, providing up to 12 hours of rock-solid, reliable protection, even in wet conditions.

The filters are produced with standard round threads according to STANAG 4155 (EN 148-1)- Rd 40 x 1/7″. In addition to a shelf life of almost double than competing filters, they also meet EN 14387:2004 + A1:2008 standards for the removal of CS/CN gas in vapor form. Individual canisters are vacuum-sealed, dated, and black in color for easy identification in inventory.

KEY FEATURES:

  • Specifically designed for law enforcement professionals for use with riot control agents/tear gases including CS, CN, and OC pepper spray
  • Hydrophobic coating on the embedded P3 filter ensures reliable function in rain, snow, or practically any conditions
  • Longer-lasting protection with almost 3X the activated carbon of competitors (250 cm3 vs. 90 cm3)
  • Delivers over 12 hours of reliable protection from riot control agents—giving officers the confidence they need to keep the peace
  • Compatible with standard 40 mm NATO-threaded respirators, which are widely available
  • 20-year shelf life—long-term savings and practical logistics with police gas mask filters that will remain usable for half an officer’s career
  • Weighs in at just 290 grams (10.2 oz) with a diameter of just 111 mm (4.3 inches)
  • Based on MIRA Safety filter design used by military personnel, CBRN specialists, and special operations forces all over the world
  • Certified by European agencies and bearing the “CE” symbol, compliant under EN 14387:2004 + A1:2008

 

When Regular Filters Just Won’t Cut it

Police in many American cities have come to realize that the filters that came with their standard riot gear start to saturate and fail fairly quickly. 

That’s where our new P-CAN police gas mask filter comes in. Designed specifically with the needs of riot police in mind, it can withstand prolonged exposure to all major riot control agents—in practically all climates—with a shelf life that spans half an officer’s career.

Exposure to riot control agents and their lachrymatory effects is enough to take an officer out of action for up to an hour. The results can only make a bad situation worse.

Protect yourself with the most cutting-edge new police gas mask filter on the market today—MIRA Safety’s P-CAN filter.

2) the filter was tested on dolomite dust clogging

ENVIRONMENTAL CONSIDERATIONS:

Thanks to its hydrophobic P3 filter that’s embedded, these police gas mask filters can be exposed to sustained heavy rainfall without water ingress. They’ve been tested to perform at temperatures as low as -32° Celsius and exposed to temperatures of up to 159° Fahrenheit. They’re also functional in a full range of humidity—from 5% all the way up to 100%. Salt breeze will not deteriorate the filter, but prolonged exposure will limit it to a service life of 12–24 hours maximum.

STORAGE AND MAINTENANCE:

The filters are sealed in plastic bags by the manufacturer. Store the filters unopened in a clean area with an even temperature, preferably 23 to 86°F (-5 to +30°C) and relative humidity below 80%. The storage period (month and year) for filters is clearly marked on the filter label. Do not try to regenerate the filters. Never clean the filters with compressed air or compressed water.

DISPOSAL:

After use, remove from the respirator and treat the filter as special refuse and dispose of as solid waste in accordance with current waste treatment regulations based on the substance(s) filtered (gasses or particles). Please consult the appropriate local authority and/or regulations for disposal advice and locations.

PRODUCT SPECIFICATIONS

With a facepiece crafted from robust and CBRN-compliant bromobutyl rubber, the CM-6M Tactical Gas Mask protects your face, internal organs, and respiratory system against a full spectrum of toxic industrial chemicals (TIC) and chemical warfare agents (CWA), including chemical, biological, and nuclear threats such as radioactive dust, noxious gas, vaporized pollutants, and more.

Complementing this durable exterior is the respirator’s inner mask, which employs a unique hypoallergenic compound.

This formulation confers a few benefits. First, it increases the mask’s tightness whilst reducing contact with the visor, which prevents fogging. Next, it decreases carbon dioxide content in the respirator’s inner space, which–together with its favorable inhalation/exhalation breathing resistance–decreases the physiological burden for the user. This provides more comfortable and practical all-day use.

Another highlight of the mask is its speech diaphragm, which ensures at least 95% intelligibility, allowing for easy communication with other members of your party. What’s more, the CM-6M is equipped with a six-point rubber-textile head harness, enhancing the respirator’s tight and lasting fit.

Note that the CM-6M CBRN gas mask is produced in one size. To ensure proper functioning, the wearer’s face must be smooth, free of facial hair, sideburns, and other hindrances at the points of contact.

Though this may be something of a disappointment to our stubble-sporting customers, we have good news for those who are vision-impaired–the CM-6M tactical gas mask is compatible with the MIRAVISION Spectacle Kit (sold separately). Featuring simple installation, this kit offers full-vision clarity to those who prefer not to wear contact lenses.

And, of course, the CM-6M mask can be outfitted with a variety of filters. This is done by screwing to the left or right inhalation chamber. Note that the unused chamber (without filter) is sealed with an inhalation chamber plug. It is therefore necessary to ensure the plug is properly screwed and tightened.

Also bear in mind that the respirator’s inhalation chambers are ONLY compatible with Rd 40 x 1/7” thread in accordance with the EN 148-1 standard.

When selecting a suitable filter, there are a few things one should consider. First and foremost, there is the type and concentration of the anticipated toxic agent(s). Next, one must remember that the CM-6M tactical mask, equipped with a TIC or CWA filter, is only safe for use in an environment containing at least 19.5% oxygen. (For further principles of filter selection and application, please consult the filter user guides.)

Additionally, it is crucial to note that the CM-6M tactical gas mask can only be used in class 1 explosive environments–i.e., areas where flammable gasses or vapors exist, or could exist, in amounts that can create explosive or ignitable conditions.

And perhaps most importantly, the CM-6M mask meets all of the requirements for class 3 of the EN 136:1998 standard. This represents the highest level of protection provided by full-face masks as specified in the standard. Class 3 masks are full-face masks made of rubber or silicone, offering a higher level of protection, durability, and resistance against extreme conditions compared to the previous two classes.

As such, the CM-6M can be used for a variety of applications. Originally designed for use in industry, agriculture, law enforcement, professional rescue/biomedical squads, and civil defense settings, this gas mask is perfect for riot gear (as a riot control mask), EDC (everyday carry), and CBRN protection.

TECHNICAL SPECIFICATIONS

560g 95%

STORAGE

The CM-6M tactical gas mask must be stored in a dark, cool and dust-free place free from sudden temperature changes. The storage room should be ventilated regularly. Temperatures may vary between 10°C and 25°C within relative humidity up to 65%. Full face gas masks must not be exposed to radiant heat or sunshine. Fuels, solvents, lubricants and other inflammable substances, including chemicals, must not be stored with masks. Moreover, there must not be any electrical machines or appliances that produce sparks or discharges during operation (ozone creation).

Avoid deformation of the rubber parts of the facepiece and internal CBRN gas mask during storage.

The CM-8M tactical, air-purifying respirator is a next-gen CBRN mask, specially engineered to meet and exceed the strictest military requirements. Thanks to a unique new visor design, it provides unparalleled visibility combined with optics compatibility, along with a six-point mesh head harness for added stability. Like all MIRA Safety CBRN gas masks, it also provides trusted protection from a full spectrum of toxic industrial chemicals (TIC) and chemical warfare agents (CWA) including chemical, biological and nuclear threats such as radioactive dust, noxious gas, vaporized pollutants and more.

Key Features of the CM-8M Full-Face Respirator:

  • Contoured panoramic visor provides maximum field of view (92.5%) while preserving compatibility with night vision goggles, thermal optics and scopes
  • 20-year shelf life
  • Uses widely available NATO-standard, 40-mm filter cartridges
  • Durable bromobutyl rubber construction (meets CBRN protection standards)
  • Tested for compatibility with a variety of high-cut helmets
  • Hypoallergenic inner mask prevents fogging, even under hard use
  • Tested resistance to mustard gas penetration for nearly 30 hours
  • Fits up to 2 standard 40-mm 1/7” NATO filter cartridges (widely available with varying protection levels)
  • Can be used with a single filter on either side to ensure proper cheek weld for left- or right-handed shooters
  • Comes with a pre-installed hydration system and canteen
  • Compatible with CamelBak water bladders with a Type M adapter (not included)
  • Compatible with MIRA Safety gas mask microphone (sold separately)
  • Compatible with MIRA Safety gas mask replacement parts kit
  • Conforms to European quality and sustainability standards, marked with the CE symbol
  • Meets all requirements under EN 136:1998, Class III
  • Complies with all standards under EN 168 for impact protection, making this the perfect mask for riot control situations
  • Carries MIRA Safety’s 1-year manufacturer warranty
  • Manufactured in the Czech Republic

Maximum Situational Awareness

The CM-8M features a radically re-engineered visor that combines an unmatched field of view (over 92%), with a contoured shape that’s 100% compatible with popular night vision, scopes and thermal optic setups. That means preserving crucial peripheral vision while ensuring functionality in even the most hostile environments. That means not just an enhanced field of view, but enhanced overall awareness—allowing you to quickly and confidently assess and engage threats as needed.

CM-8M Full Face Respirator Sizing

For the initial launch, the CM-8M will come in one universal size. The fit will be similar to the medium CM-7M, and the CM-6M, which also come in one universal size. We do not recommend this mask for people with smaller-than-average head shapes, nor do we recommend it for above-average head shapes. Always conduct a negative pressure test to ensure you are getting a tight seal, and conduct this test each time when donning the mask.

The CM-8M has been tested with a wide variety of high-cut helmets and shown to integrate seamlessly. However, if the wearer has a small head, the mask may not fit well with a helmet.

Mission-Flexible

As opposed to some full-face respirators that are extremely specialized and mission-specific, the CM-8M was designed as a mission-flexible upgrade for civilians, law enforcement and military alike. Since it’s not a dedicated military mask, that means everyone can tap into the same level of protection that’s trusted by top Special Forces.

MIRA Safety Strategic Support

The CM-8M is part of the MIRA Safety family of masks; which means it uses the same filter cartridges, components and optional upgrades as your existing MIRA Safety masks. It’s compatible with the MIRA Safety Microphone System and Replacement Parts Kit, and it features the same basic construction as your existing MIRA Safety masks; allowing for rapid transition and upgrade to the CM-8M from existing platforms.

Technical Specifications

The CM-8M gas mask is made from thick bromobutyl rubber (CBRN-compliant) with a polycarbonate mask and a 6-point mesh head harness to ensure a rock-solid fit for users of all sizes.

The key improvement for the new CM-8M is its uniquely-contoured polycarbonate visor, combining unparalleled field-of-view with a flat front that works perfectly with all your optics and NVG systems.

We’ve also refined our existing gas mask designs, maximizing ergonomics and minimizing the overall size of the mask. The full-face respirator’s inner mask is made from a special hypoallergenic compound that prevents fogging and reduces carbon dioxide(CO2) content in the mask’s inner space, improving comfort for long hours of potential usage.

The CM-8M features a central speech diaphragm that ensures at least 95% intelligibility of speech; however the gas mask microphone is strongly recommended as an upgrade for all MIRA Safety masks. MIRA Safety replacement parts are compatible with the CM-8M mask, and more new accessories will be available for the platform soon.

Like all MIRA Safety masks, the CM-8M is designed for use with “NATO standard” filter cartridges (Rd 40 x 1/7” thread in accordance with the EN 148-1 standard).

Selection of a suitable filter depends on the type and concentration of anticipated toxic agent. The CM-8M

air-purifying mask equipped with a TIC or CWA filter is only safe for use in an environment containing at least 19.5% oxygen. The principles of filter selection and application are described in the filter user guides.

The CM-8M tactical gas mask may be used in class 1 explosive environments only. The CM-8M mask meets all of the requirements for class 3 of the EN 136 standard. It’s a great choice for riot gear or as a riot control gas mask.

TECHNICAL DATA

WEIGHT: 540g INTELLIGIBILITY OF TALK: 95%

MIRA Safety gas masks come with enhanced speech diaphragms that allow for improved communication over shorter distances. But talking through a gas mask is never easy. Especially if you’re not right next to each other or you’re dealing with any noise, weather, or other distractions.

The MIRA Safety Gas Mask Microphone is cross-compatible with all CM series adult-sized MIRA Safety gas masks (CM-6M, 7M, 8M), making it easy to swap between masks for different types of missions. 

Installation takes just a few seconds, and you’re ready to connect to your existing communication system. Just like a standard headset, the microphone requires no additional power, and it has an average life expectancy of 30,000 hours.

Gas mask microphones are a relatively minor upgrade that can make a massive difference while using your mask. Communicating via hand signals is difficult in the best situation, and it’s impossible if you’re holding a rifle or riot shield. Having the ability to plug into your existing comms helps you stay better informed and make better decisions when they matter most.

Description

IMPORTANT NOTE: The VPU-1 requires the 3.5mm jack version of the MIRA Safety gas mask microphone (sold separately).

The MIRA Safety VPU-1 Respirator Voice Projection Unit amplifies and projects your voice while wearing a respirator. It’s an ideal solution for professionals who need to be heard loud and clear, but who also need to wear a PPE mask on duty. Working with your existing gas mask and gas mask microphone, our VPU features a rechargeable battery and is optimized to withstand exposure to extreme temperatures, vibration, water, salt fog, and dust.

Key Features of the MIRA Safety VPU-1 Respirator Voice Projection Unit

  • Included rechargeable Lithium-Ion battery
  • IP67 certified (IEC standard 60529, submersible for up to a half an hour)
  • Simple, easy-to-use interface with just three buttons
  • Delivers maximum sound pressure level of 83 dBSPL @ 1 m
  • Connects directly to MIRA Safety Gas Mask Microphone that can be mounted on your respirator’s exhalation valve
  • Robust MOLLE clip allows for easy mounting and handling
  • Volume range +24 dB to -80 dB
  • Integrated battery allows for up to 6 hours of continuous use with 2 hours of charging
  • Designed in accordance with ČSN EN 140
  • Approved according to PPE directive 89/686/EEC and EMC directive 89/336/EEC

 

Technical Specification

The MIRA Safety VPU-1 dramatically increases your ability to communicate while wearing a gas mask or half-face respirator.

This is a critical advantage for riot police, SWAT teams, military operators, and industry professionals who regularly wear CBRN gear. But it’s also a major asset for anyone who might have to communicate with a small group on the move without compromising their PPE.

Without a VPU, your ability to communicate can be limited by your gas mask’s speech diaphragm. A gas mask microphone helps solve that problem, but it also means that everyone in your party needs a radio (and to know how to operate it) in order to communicate.

With a VPU, you can effectively communicate over a much larger area, even in distressing or distracting situations. 

The MIRA Safety VPU-1 integrates seamlessly into your existing gear, including our Gas Mask Microphone and any compatible gas mask or respirator. It’s IP67-certified with rugged construction and a runtime of up to 6 hours.

USE:

The unit features a rugged MOLLE clip that can be attached to a plate carrier, belt, or other MOLLE webbing (including our MOLLE PAPR Pouch). Before mounting the VPU, perform a battery test and plug in the two-pronged cable from your gas mask microphone. Switch the unit on, select your desired volume, and mount the microphone. Note that acoustic feedback may occur if the VPU is placed too close to your gas mask microphone. To eliminate feedback, either reduce the volume or increase the distance between the VPU and the microphone. 

 

STORAGE

Store your MIRA Safety VPU-1 Respirator Voice Projection Unit in a cool, dry place away from direct sunlight. Ideal temperature for storage is -20 to +45°C (-4°F to 113°F). Lithium Ion batteries typically hold a charge for up to 12 months in storage. Periodic battery testing is necessary every 6 months to maintain a full charge.

GAS MASK FILTER LIFETIME:

Breakthrough time of a gas mask filter is tested according to EN 14387+A1 at humidity 70% and flow rate 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 a filter may, under normal conditions, calculated by comparing the concentration at the workplace and the minimum Dynamic Adsorption Capacity (DAC) for the filter.

GAS MASK FILTER STORAGE AND MAINTENANCE:

Each NBC-17 SOF gas mask filter is sealed in a plastic bag by the manufacturer. Store the filters unopened in a clean place at even temperature, most appropriate at -5 to +30°C and relative humidity below 80%. Sealed filters tolerate also conditions of -30 to +50°C and RH below 95%. The storage period (month and year) for filters is marked on the filter label. Do not try to regenerate the filters. Never clean the filters with compressed air or compressed water.

GAS MASK FILTER DISPOSAL:

After use, gas mask filters are considered special refuse. Make sure that they are disposed of according to the filtered substance (gases or particles) in accordance with current waste treatment regulations. If the product is to be disposed of, it should be dismantled from the respirator and disposed of as solid waste. Please see local authority regulations for disposal advice and locations.
