Maximum Situational Awareness

The CM-8M^® Full Face Respirator 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 gas 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 gas 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 gas mask may not fit well with a helmet. 

As opposed to some full-face respirators that are extremely specialized and mission-specific, the CM-8M^® Full Face Respirator was designed as a mission-flexible upgrade for civilians, law enforcement and military alike. Since it’s not a dedicated military gas 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 gas masks; which means it uses the same filter cartridges, components and optional upgrades as your existing MIRA Safety^® gas 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.

The CM-8M^® full face respirator 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 gas 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 gas 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^® gas masks. MIRA Safety^® replacement parts are compatible with the CM-8M^® gas 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 full face gas 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^® gas 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.

To help our customers make the right purchasing decision, I like to share a bit of product history—along with a summary of the benefits and limitations—based on my personal experience and direct feedback from users.

 The CM-8M^® was designed as a “best of both worlds” gas mask, combining features from the CM-6M^® and CM-7M^®. It offers a wide panoramic field of view like the CM-6M^®, while still allowing users to comfortably shoulder a rifle, much like the CM-7M^®. Originally developed under the name OM-2020, the mask is manufactured in the same Czech facility as our other premium respirators and shares many of the same components (aside from its unique visor designed for enhanced situational awareness). 

When it was first developed a few years ago, we encountered a few issues, all of which have since been addressed.

Early versions had some minor distortion around the periphery of the visor. To fix this, we’ve partnered with a new Italian manufacturer to produce a much-improved lens that’s now standard across all CM-8M^® units.

We also received feedback about the oro-nasal cup applying too much pressure on the bridge of the nose for certain face shapes. We revised the cup design accordingly, and haven’t received any complaints since.

Another issue was that the hydration straw was slightly too short for some users. We’ve corrected this in newer production runs, and we offer free replacement straws to any customers who need them. Going forward, all CM-8M^® masks will include the upgraded straw.

Limitations to consider:

Because the visor is rigid and does not flex like the CM-7M^®, the mask doesn’t conform to the face in the same way. For users with very narrow faces, this can potentially lead to a minor sealing issue around the temples. 

While the cheek weld on the CM-8M^® is excellent, you may still benefit from using an optics riser on your rifle to ensure proper alignment and comfort. And because the visor is made of polycarbonate, I highly recommend picking up a pack of tear-offs to protect it from scratches during heavy use.

Lastly, although this mask pairs very well with high-cut helmets, it may not be ideal for use with low-cut helmets due to the visor shape.

The CM-8M^® air-purifying full face 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%. NBC 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 gas 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.
