The CM-7M CBRN tactical gas mask was designed and developed in cooperation with Czech Army specialists and specifically developed for use with a wide array of optics for advanced tactical capability.
The CM-7M hazmat mask meets the EN 136 (Class III) and EN 148-1 standards and is available in three sizes, providing a perfect fit for practically any user. A NATO-standard filter canister can be mounted on either (or both) side of the military mask to make it easier to aim a gun whether right- or left-handed.
The material of the facepiece (bromobutyl rubber) on this NATO gas mask provides extraordinary protection against all known chemical warfare agents, along with biological, nuclear, radiological, and industrial chemical agents.
This tactical gas mask is designed to withstand long-term use in any weather conditions. The inner mask features comfortable hypoallergenic construction that reduces the content of carbon dioxide in the mask and regulates the flow of inhaled air to prevent fogging for more comfortable all-day use.
The inhalation chambers on this army gas mask are fitted with the Rd 40 x 1/7” thread in accordance with the EN 148-1 (NATO) standard. This ensures compatibility with the widest range of filters readily available on the market today.
These military-grade gas masks are manufactured under the permanent supervision of a representative of the Czech Ministry of Defense and are trusted by military and police users in a wide variety of countries.
The lenses of the CM-7M warfare mask are specifically crafted to ensure compatibility with all kinds of optical devices while providing a sufficient field of vision. The dual lens configuration provides superior depth perception when compared to a single panoramic faceplate, making it ideal for use with rifle iron sights or in combat.
The CM-7M nuclear gas mask is equipped with a drinking system that enables safe drinking in contaminated areas. The drinking system is also compatible with CamelBak hydration systems.
Tactical Gas Mask Service Life
The storage and service life of the CM-7M full-face respirator / tactical gas mask is 20 years from the date of production, provided that the recommended storage conditions are observed.
|Size No.||Size in mm|
|Size 1||5.19 – 5.51 inch (small)|
|Size 2||5.51– 5.82 inch (medium) (universal most used)|
|Size 3||5.82 – 6.14 inch (large)|
To size yourself, it would require a device called a faciometer which is not very common.
Size 2 (medium) fits 95% of the population, so if you're an average size person, we would suggest size 2. For smaller than average people who weigh 130lb or less, with thin faces, we would suggest size 1 (small). For users over 250 lbs and wide faces, go with large.
We have a free exchange program in case it doesn't fit, so rest assured that no matter what we'll make sure you get the right size. You will know the size is right if you do a negative pressure test (blocking the inhalation valve and taking a deep breath), and the mask seals tightly to your face.
Please Note: Filters are NOT included. Please make sure to choose the appropriate size on the drop-down menu.
QUESTIONS & ANSWERSAsk a Question
Would it be possible to get sunlight lenses or outserts for the CM-7M?
At this time, we do not carry any outserts or lens covers for the CM-7M, and we do not know of any aftermarket alternatives.
Can the CM-7M size small fit a 10-year-old face?
In most cases, no it cannot. The size small is made for small adults with narrower face profiles, 5'3 or shorter, weighing in at 130lb or less. If the small CM-7M mask doesn't fit, the only other alternative from MIRA Safety is the CM-2M size 2.
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.
What are the major differences between the CM-6M and CM-7M?
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.
How do I determine the correct size for the CM-7M?
Sizing yourself would require a device called a faciometer, which is not very common. Size 2 (medium) fits 95% of the population, so if you're an average size person, we would suggest size 2. For smaller than average people who weigh 130lb or less, with thin faces, we would suggest size 1 (small). For users over 250 lbs and wide faces, go with large. We have a free exchange program in case it doesn't fit, so rest assured we'll make sure you get the right size.
How does the mask fit if you have a thick mane of hair (female)?
Considering the straps are elastic, they are designed to fit hair. The mask should fit just fine.
Do these masks come with a case for storage? If not, what do you suggest?
Do you need to run 2 filters or can you use only 1?
We suggest using one at a time, but you have the option of using one or two.
The mask supports breathing apparatuses, does this include SCBA’s?
This mask is not compatible with SCBA systems, but it is compatible with PAPR's.
Does mask come with filters already?
No, it does not. Filters are sold separately.
Would this mask be compatible with night vision goggles/monoculars mounted on a helmet?
Yes, it will. Many of our customers are using this mask with common PVS-14's and PVS-15's. It is compatible with a wide array of night vision equipment.
I live in CA and have a serious lung condition. Basically any fume or smoke will send me into respiratory collapse without the use of an EPIPEN. I am in serious need of something completely protective or I in all reality may die next time big fires break out. Please let me know if the CM-7M is a good choice.
Coupled with the correct filter, the CM-7M is a good choice. The better choice would be the CM-6M if there is no tactical application needed, as it has better peripheral vision.
Can glasses be worn with this mask and still create a tight seal? Also would a beard have to be shaved off?
Glasses cannot be worn with this mask as it would break the seal at the temples. There may be a 3rd party spectacle kit available for the CM-7M, but we do not know of any at this time. I would suggest contacting a company that specializes in spectacle inserts to see if anything is available. Considering a beard would break the seal of any gas mask, yes, it would have to be shaven off.
Could you use this for Airsoft without damaging the filter system? I have asthma and the smoke Grenades make it hard to breathe.
Yes, you could use it for Airsoft, and as long as you use it with 40mm NATO filter cartridges, you will not damage the filter system.
Do you have any masks with HEPA filters?
All of our filters have a P3 filters built-in, which uses high-grade HEPA/ULPA filtration paper.
Will this mask need to be stored in a special temperature? Also, will it protect me from a biological agent that is very contagious?
Ideal storage conditions for our masks are 50-70° F. When coupled with the correct filter, other pieces of personal protective equipment, and is used as per best practices, it will protect your eyes and breathing organs from biological agents.
Can you change the filter while in a contaminated area, without compromising the mask?
Yes, you could, but this would require training on donning and clearing the mask. Filter changes while in a contaminated area should not be attempted unless you are properly trained in the procedure.
Would this mask protect me from the Coronavirus?
Coupled with the appropriate filter, other personal protective equipment to cover your skin, and proper decontamination measures, yes it will protect form coronavirus.
Is the plastic insert supposed to be removed when using the mask, if so how do you remove it carefully without damaging the mask?
Yes, it is. The plastic insert is meant to maintain the shape of the mask (preventing deformation) when in storage. To remove the plastic insert, lift one end of the insert up towards the visors until you can clear the chin seal, and then do the same on the other side.
Do the CM-7M lenses have some sort of Ballistic protection capability?
They are made from impact-resistant tempered silicate glass, as mandated by the Czech special forces for optical clarity. However, they do not offer ballistic protection.
Are there any outserts available for the CM-7M such as a UV filter (sunglasses)?
We are not aware of any compatible outsets, but there may be aftermarket options.
I purchased a CM-7M mask not to long ago, (I absolutely love it) and I wanted to make sure I was storing it right. Is storing it in a waterproof hard case with silica gel packets a good way to store it or should I store it differently?
Glad you love it! That is an excellent way to store it, make sure it's in a cool, dark place, without high temperature and humidity changes. Also, make sure to store it with the black plastic insert installed, as this helps maintain the shape of the mask when not in use.
On the CM-7M, can it accept prescription inserts or only the CM-M6 is capable of doing so?
At this time, we do not have a spectacle kit available for the CM-7M, and we are unsure of which kit fits with the mask. I would suggest reaching out to Safe Vision, a 3rd arty provider, as they have many kits available. The CM-6M is compatible with the 3M Safet 6878 Spectacle Kit, which is available across many online shops.
This mask is a great improvement from the M17 I used in the Army. More comfortable to wear and you can change the filter while wearing the mask. Also notice I don't get the fogging I used to get in the M17. Very pleased with the quality. So much so, that I bought two more for my family members. Hope to never need them but sleep well knowing I have them. I was lucky and bought early so have mine in hand.
I received my mask a few days ago (still waiting on the filters, but it is to be expected with everything that is going on in the world right now). It fits really well and breathing is pretty easy, I have not tested the canteen out yet but I thought it was a nice touch seeing as how I'm going to be having to wear this for several hours while passing out food to those effected by the pandemic. Great product, everything that i expected and quite comfortable to wear. FOREWARNING THOUGH: To get a good seal, it is strongly advised that you shave your face, I wasn't able to get a proper seal due to facial hair and unfortunately I am going to have to shave all that off :( . A big thanks to the mira team on the expedited shipping ( volunteering with first responders to pass out food on memorial day) as it got here before my trip. Their support staff was very responsive and helped me through this a lot, in particular Max he was very professional and responded quickly even with all the backlog and regulations that they were dealing with.
I purchased the CM-7M for myself & CM-6M for my wife. Expectations were exceeded on masks & filters. We both work in hospital emergency healthcare setting. We never leave the house without our masks. Perfect fit, excellent seal, extremely comfortable & hydration system works great after a few minutes of getting familiar with it. My true reason for purchasing such a high end product isn't Covid-19, although I did purchase both the P3 virus & the NBC-77 filters. Rather it's to be prepared for any possible civil unrest related issues that might result in a smoke, biological or gas event. My wife is very pleased with the full face on the 6M & the 7M works great when I have my AR or 9mm and need the scope or sights. If you want true piece-of-mind MIRA is the way to go. The web site clearly states that you need to purchase filters & storage bag separately. If you don't understand why, you probably should go to Home Depot and get a paint mask.
Seems to be a good mask. Fits secure. Straps are not as good as they should be for the rebranded version with extra cost. Should have came with a storage bag.
I haven’t received the filters yet and it has been months. I want the filters!!!!!!!!!!!!!!!!!!!!!!! Very bad experience so far
