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.

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.

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. 

To size yourself, it would require a device called a faciometer which is not very common. The CM-6M only comes in one universal size (medium) that fits 95% of the adult population. If you're an average size person, then a CM-6M or a size 2 (medium) CM-7M is fine. For smaller than average people who weigh 130lb or less, with thin faces, we would suggest size 1 (small) of the CM-7M mask. For users over 250 lbs and wide faces, go with size 3 (large).

If you're an average size person, then a size 2 (medium) CM-7M is fine. For smaller than average people who weigh 130 lbs or less, with thin faces, we would suggest size 1 (small) of the CM-7M mask. For users over 250 lbs and wide faces, go with size 3 (large).

Below is a sizing table of the CM-7M, based on the measurements of a faciometer.

Size No. Size in inches
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)

Yes, you'll definitely need a large-sized CM-7M.

There should be a number on the mask that will indicate its size (1 for small, 2 for medium, and 3 for large).

Yes, it is. That is the same setup someone on our team is running.

The standard speech diaphragm is just a vibrating piece of material that makes sound more audible for the people around you. This is not a microphone or and electronic device. We've just released our very own Microphone (click here for the product page) that works with the CM-6M, CM-7M, Half-Face Respirator (TAPR), and CM-8M (not yet released). This microphone is configured for use with Peltor headsets, and you can connect a Baofeng radio to the Peltor as well.

The CM-7M lens is impact resistant to Czech Military standards, and they did their own testing on it which is not public. During the development of the mask, they requested silicate glass of a certain thickness, and with internal testing, it was approved for their needs.

We do not have a VPU available at this time, but we are working on a solution. The mask does, however, have a built-in speech diaphragm to make communication easier. Stay tuned.

In order to connect this mask, you would need a CamelBak type M adapter and a bladder that is compatible with this adapter. For CBRN applications, we would suggest the CamelBak Chem-Bio Reservoir 4.0. For non-CBRN environments, we suggest the CamelBak Antidote Reservoir. We will make a video in the future to illustrate this.

Yes, each mask comes with 1 filter port cap straight out of the box.

Considering the straps are elastic, they are designed to fit hair. The mask should fit just fine.

This product listing does not include a pouch. We have the NBC Kit available with the MIRA Safety gas mask pouch included, or you can purchase it separately. In general, you can use any gas mask pouch on the market for storage and safekeeping.

We suggest using one at a time, but you have the option of using one or two.

This mask is not compatible with SCBA systems, but it is compatible with PAPR's.

No, it does not. Filters are sold separately.

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.

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.

Glasses cannot be worn with this mask as it would break the seal at the temples. We recommend our MIRAVISION Spectacle Kit instead. You'll have the option of choosing from different lens types and colors. As part of the order process, we require a current prescription. You can either upload the prescription on the product page or send it to us via email at support@mirasafety.com.

I'm afraid we don't have masks that are built to fit people with facial hair as most respirator masks rely on a tight facepiece seal to achieve maximum protection. Facial hair is also a common reason that someone cannot be fit tested. To ensure proper functioning, the user’s face must be smooth, free of facial hair, sideburns, and other hindrances at the points of contact.

For emergency situations where most individuals aren't clean-shaven, we recommend keeping a beard trimmer in your kit. That way, you'll be able to quickly get rid of any facial hair in case something unexpected happens. It is also worth noting that the only thing that works for people with beards are hooded respirators which typically run on a PAPR (Powered Air-Purifying Respirator) setup.

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.

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

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.

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.

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

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.

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.

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

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.

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 MD-1 Large (click here for the product page).

Yes, it can as long as you purchase it with the MIRAVISION Spectacle Kit. You have the option of choosing from different lens types and colors. As part of the order process, we require a current prescription. You can either upload the prescription on the product page or send it to us via email at support@mirasafety.com.

Thank you so much for those kind words! We appreciate your feedback and are excited that you found MIRA Safety.
