MIRA Safety CM-7M Military Gas Mask CBRN Protection Military Special Forces, Police Squads, and Rescue Teams

Q: Would it be possible to get sunlight lenses or outserts for the CM-7M?

A: 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.

Q: Can the CM-7M size small fit a 10-year-old face?

A: 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.

Q: How would you know if a gas mask fits your face?

A: 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.

Q: What are the major differences between the CM-6M and CM-7M?

A: 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.

Q: How do I determine the correct size for the CM-7M?

A: 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.

Q: Can glasses be worn with this mask and still create a tight seal? Also would a beard have to be shaved off?

A: 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.

Q: Could you use this for Airsoft without damaging the filter system? I have asthma and the smoke Grenades make it hard to breathe.

A: 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.

Q: Do you have any masks with HEPA filters?

A: All of our filters have a P3 filters built-in, which uses high-grade HEPA/ULPA filtration paper.

Q: Will this mask need to be stored in a special temperature? Also, will it protect me from a biological agent that is very contagious?

A: 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.

Q: Can you change the filter while in a contaminated area, without compromising the mask?

A: 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.

Q: Would this mask protect me from the Coronavirus?

A: Coupled with the appropriate filter, other personal protective equipment to cover your skin, and proper decontamination measures, yes it will protect form coronavirus.

Q: Is the plastic insert supposed to be removed when using the mask, if so how do you remove it carefully without damaging the mask?

A: 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.

Q: Do the CM-7M lenses have some sort of Ballistic protection capability?

A: 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.

Q: Are there any outserts available for the CM-7M such as a UV filter (sunglasses)?

A: We are not aware of any compatible outsets, but there may be aftermarket options.

Q: I purchased a CM-7M mask not too 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?

A: 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.

Q: On the CM-7M, can it accept prescription inserts or only the CM-M6 is capable of doing so?

A: 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.
