The CM-6M Tactical Gas Mask has a facepiece of tough bromobutyl rubber (CBRN-compliant) for maximum resistance to TIC/CWA contaminants. The full-face respirator’s inner mask is made from a special hypoallergenic compound that ensures excellent tightness and avoids exhaled air contact with the visor to prevent fogging. It also reduces carbon dioxide(CO2) content in the mask’s inner space, which together with its favorable inhalation/exhalation breathing resistance, decreases the physiological burden for the user—providing more comfortable and practical all-day use.
The integrated speech diaphragm ensures at least 95% intelligibility of speech, allowing for easy communication with other members of your party. The mask is equipped with a five-point rubber-textile head harness to ensure a snug and lasting fit.
The CM-6M CBRN gas mask is produced in one size. To ensure proper functioning, the user’s face must be smooth, free of facial hair, sideburns and other hindrances at the points of contact.
The tactical gas mask is compatible with the 3M Safety 6878 Spectacle Kit (sold separately), with simple installation for those who are vision impaired and prefer not to wear contacts.
The filter is fitted to the mask by screwing to the left or right inhalation chamber. The unused chamber (without filter) is sealed with an inhalation chamber plug. It is necessary to ensure the plug is properly screwed and tightened.
Inhalation chambers of the CM-6 mask are ONLY compatible with 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-6 tactical 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-6 tactical gas mask may be used in class 1 explosive environments only. The CM-6 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.

The CM-6 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.
QUESTIONS & ANSWERSAsk a Question
I purchased the 3M 6878 Spectacle Kit for the CM-6M gas mask. I am wondering how you attach the frame holder into the mask. I get a general idea from the pics on your website, But I can\'t see how the top \"L\" bent piece sits in the mask. It looks like there is some type of mounting block inside the mask itself. Any help would be awesome!
The "L" piece goes underneath the rubber block, and it is held in place by the pressure that this knob puts on the metal bracket. The bottom of the spectacle kit lodges itself right above the oro-nasal cup.
Is it possible to shoot weapons when wearing your CM-6M Tactical Gas Mask, or is this only possible with the 7M Mask because of the design?
Considering the design of the visor on the CM-6M, it will be more difficult to get a good cheek weld (pressing your cheek on the stock to get a sight picture). If the sight is raised, thus requiring less of a weld, it would work better with the CM-6M. We do not recommend using magnified optics with the CM-6M as it would be harder to get eye relief (distance from the last surface of an eyepiece within which the user's eye can obtain the full viewing angle). The CM-6M and CM-7M are really different tools for different jobs. The CM-7M is superior for tactical applications, and the CM-6M is superior for everything else.
Do the mask and NBC-77 SOF filters that you can buy in the bundle both have a 20-year shelf life?
Yes, they do.
If you use it for Coronavirus, which model do you suggest? Do you need to change the filter each time if you go out with possible affected patients around?
All the masks on our website, so long as they are used per best practices and form a tight seal, would protect your breathing passages and eyes from viral threats. A filter cannot be regenerated in any way, and once used, it is considered toxic waste and must be disposed of. So to answer your question, yes, you would have to change the filter each time if it's exposed to a viral agent.
Do the CM-6M and CM-7M gas masks offer the same level of protection?
Yes, they do. The difference is in design, not the level of protection. Both are made from bromobutyl rubber that is resistant to CBRN agents, and both also have a speech diaphragm, drinking system, and come with a canteen.
How would you know if a gas mask fits your face?
You would have to perform a negative pressure test. To do this, you would put the mask on your face, take a deep breath out, cover the inhalation valve (make sure the opposite side has the 40mm cap in place), and take a deep breath. If the mask sucks tight to your face without leaking air, you know that this mask fits.
How long will a NBC-77 SOF filter protect in non-contaminated air against viruses?
As viruses travel in particles and liquid aerosols, this filter will protect you for as long as you can wear the mask (several days). Keep in mind; if you are in a contaminated environment, you would need to decontaminate properly before removing your protective gear, and then dispose of the filter as there is no way to regenerate it. Once the filter is used in a contaminated environment, it is considered toxic waste.
How long does a filter last once it's opened?
Filter use time depends on a few factors, including atmospheric conditions, contaminant type, concentration, along with your breathing rate. As a general rule of thumb, we would suggest having two filters per person per day for emergency evacuation purposes. If you'd like specific data on use time, you can look at the brochure that goes into breakthrough times along with the application.
Can this mask be attached to an oxygen tank?
No, it cannot. the oxygen tank you're referring to is called a Self Contained Breathing Apparatus (SCBA), and requires a different connection port. This mask is, however, compatible with a Powered Air Purifying Respirator (PAPR). This is a device that blows continuous filtered air into your gas mask through positive pressure and lowers breathing resistance.
I have a narrow face. Are there different sizes available for the CM-6M gas mask?
Would that mask work fine with a short (1.5 cm) face-beard?
No, it will not. When you wear any gas mask, you should be clean-shaven. If you have a little stubble, you could try to use vaseline to get a better seal, but it is NOT guaranteed to function as intended. We suggest keeping a shaver in your kit to use in case you need to deploy the mask quickly.
What is the benefit of using two filters at the same time?
Two filters would lower the breathing resistance, at the expense of added weight. We suggest using one filter at a time for most purposes.
Does the CM-6M gas mask need two filters to function?
No, it does not. You can use one filter, or two filters at the same time. With one filter, the opposite side would be plugged.
If I buy the NBC-77 SOF filter cartridges bundled with this mask, do they come pre-attached to the mask or are they capped or sealed separately for later attachment?
They come capped and sealed, not pre-attached. Filters should remain sealed until they are ready for use.
Do you have plans to start offering PAPRs, that are compatible with your gas masks naturally? And if so when and what price tag may we expect?
Yes, we do, likely middle of 2020. As for price, we do not have those details available yet.
Can you wear glasses with the mask on? Would that compromise the mask's ability?
Standard glasses cannot be worn with a gas mask as it will break the seal. The good news is, there is an aftermarket spectacle insert that is compatible with the CM-6M, and that is the 3M Safety of 6878 Spectacle Kit. We do not sell it on our website, but it can easily be found in other shops across the web.
If the filter was exposed to the Coronavirus, would you have to replace it immediately?
Not immediately. But you would have to decontaminate your equipment before it's removed, and then the filter should be disposed of as it's considered toxic waste after coming in contact with any agents. As mentioned in a previous Q&A, you can use the filter for as long as you can wear the mask.
What are the major differences between the CM-6M and CM-7M gas masks?
The CM-7M is specially designed for use with optics and operating a rifle. Features include a dual recessed visor system for eye relief, along with a contour above the inhalation valve for a closer cheek weld. These features come at the expense of a wide field of view, and this is where the CM-6M shines. Think of the CM-7M and CM-6M as different tools for different jobs.
Does this come with the filter or must that be bought separately?
Filters are sold separately. However, when you add filters via the dropdown on this product page (located right by the add to cart button), the price of each NBC-77 SOF filter is lower than retail.
I worked in hazmat for many years, and wore a respirator almost daily when I did. So, with that in mind, I was actually quite impressed with this mask (as I could not easily find the style I used to wear on the market for civilians that wasn't crazy expensive.) Love the large field of view, and was very impressed with the speech diaphragm which seems to rival what I remember of my old 3M mask. Also love that it is compatible with camelback bladders (it comes with a canteen, by the way). That's a plus, since a drinking tube is not something I remember having on a work mask before. The only cons I would say, is that I was spoiled on the mesh harness that comes on the Scott 3M masks - those harnesses take a beating and are comfortable, but I'm not going to be wearing this mask every day - so that was an acceptable trade-off. Also, I wish they manufactured this in other sizes, but maybe that will come some day. Their other mask they sell comes in other sizes. If the mask fits you, it's hands-down a winner for a civilian respirator that's within a decent price range. I think I found the 3m mask on northern safety for $100 more and then decided on this one. (Also, I didn't compare israeli masks in my decision, as I only wanted a newly manufactured mask because I wanted something with an unquestionable shelf life. (Divide the price by 20 years and you will see that $11 a year is really very cheap when it comes to having this kind of security on hand in a rapidly changing world.) I live overseas now and we move a lot, so it feels nice to finally have a proper emergency kit in the house.
I’m an Army combat veteran with 4 tours in Iraq, and somewhat of a gas mask collector. Within my collection, I own the following: - MIRA Safety CM-6M - Drager CDR 4500 - Drager X-plore 6300 - 4A1 Israeli Civilian Mask - Israeli Military M15 Mask - Mestel SGE 150 - Mestel SGE 400/3 I originally wrote a version of this review for a Drager mask I purchased and it got a lot of helpful votes, so I figured I’d expand on it and go into detail about the MIRA CM-6M, while giving some background about the other masks I own. Considering the many options, it’s important to know what the mask is intended for, and the level of protection it offers. Keep in mind, the focus of this comparison is for CBRN applications (chemical, biological, radiological, nuclear). Also keep in mind, that a gas mask is only one component of CBRN PPE (personal protective equipment). To minimize exposure during a true SHTF scenario, you also need coveralls, gloves, boots, and Chemtape to seal up the seams. Along with that, you would need a decontamination agent such as FAST Act for equipment, and RSDL for skin. -- MIRA Safety CM-6M: PROS *Compliant under EN 136 CL3 standards for respiratory protective devices. *Large visor with a very wide field of view. *Made from butyl rubber which meets material specifications for CBRN protection. *Comes standard with a speech diaphragm. *Comes standard with a pre-installed drinking system and external canteen. *Compatible with CamelBak water bladders. *Fits standard 40mm filter cartridges, which are widely available. *Fits up to 2 filter cartridges simultaneously, increasing the time you can go without changing filters, and making it easier to breathe under physical exertion, or for people with smaller lung capacities (kids). *Used by military in Europe and the Middle East. *Long shelf life of 20 years. CONS *Has a slight rubber smell. In all fairness, all butyl masks that I own also have some rubber smell, just figured I’d mention it just in case someone reading is very sensitive to this. *It’s not NIOSH CBRN Approved so it would limit professional use in the USA (Most government agencies require NIOSH CBRN approval for respiratory devices as part of OSHA standards if using the mask as part of your workplace PPE). Definitely great to have, but having or not having this certification does not determine quality, just means it went through and passed a certain series of tests here in the US. --- Drager CDR 4500: Fantastic all around mask that I have now designated as a preparedness backup after my CM-6M and DHS 7000. The lack of a drinking system made me seek out other options as gas masks get pretty stuffy, and taking off the mask for some water while getting out of dodge may not be an option. Drager X-plore 6300: The structure of this mask is identical to the CDR 4500, with some slight color variation. The major difference is the rubber used for this mask is not NIOSH CBRN approved. However, It does have a NIOSH rating for use against many gases, chemical agents, and particulates. This mask holds an EN 136 CL 2 certification. 4A1 Israeli Civilian Mask: Sold mostly in surplus stores and can be picked up for under $30. Visibility is poor considering the small visors, one for each eye. Many people in Israel have this mask in case of emergency, and I’m sure it’s saved lives over the years, but I would not trust it considering most are surplus and could have been sitting around for 20+ years. This mask is not rated for CBRN purposes. Also, do not use the supplied filter as most are long expired. Israeli Military M15 Mask: Similar specs to the 4A1, but with bigger visors. These do expire (20 yr life), so keep that in mind if purchasing. I’ve owned 5 M15 surplus masks over the years and 3 had damaged valves, leading to a return. These masks are resistant to certain warfare agents, but not the full gamut. I would recommend looking up the spec sheet for more detail. Mestel SGE 150: This mask looks really nice, but is not intended for CBRN purposes of any sort. There is no coating on the visor against chemical irritants, and there is no CBRN certification. Primary use for this would be against tear gas, pepper spray, and riot situations. Mestel SGE 400/3: Same as the SGE 150, but with 3 filter ports instead of one. This mask also has a few optional accessories. Retail is around $200, and can cost upwards of $400 when fully loaded with accessories (speech diaphragm, drinking module, canteen). If you want the extra accessories, you either have to buy it pre-installed, or send it back to the factory for professional installation which could take weeks. This is a great mask to block tear gas if you’re stuck in a riot, but is not intended for CBRN applications.
I have yet to truly unpack everything and Use it. Im keeping it sealed as part of my disaster kit. The service was excellent asked some questions before purchased, had them answered that evening. I ordered and it arrived in a timely manner and on the expected shipping date Overall experience was excellent And i will be purchasing from them again!
The is a great mask. Comfortable to wear and at an affordable price. Versital when paired with the available different filters.
Ordered this mask and filter combo for upcoming local events - not Only was it purchased at a great value BUT shipping was crazy fast. Got my order in 4 days - one of which was New Year’s Day! Can’t say enough positive things! Super comfortable, can wear for extended periods without getting a headache, easy to adjust and outstanding vision. Love it!
