The CM-7M® military gas 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 side of the military gas mask to make it easier to aim a gun whether right- or left-handed.
The material of the facepiece (bromobutyl rubber) on this CM-7M® military gas mask provides extraordinary protection against all known chemical warfare agents, along with biological, nuclear, radiological, and industrial chemical agents.
This tactical military gas mask is designed to withstand long-term use in any weather conditions. The inner mask features a 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 full face respirator’s 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 professional-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® CBRN gas 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 iron sights or in combat.
The CM-7M® military standard 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.

MIRA Safety CM-7M® Gas Mask Size Chart
| Size No. | Facial height (nose bridge – chin) | Width of the face (bizygomatic width) |
|---|---|---|
| Size 1 | 108 – 120 mm | 125 – 140 mm |
| Size 2 | 120 – 128 mm | 140 – 148 mm |
| Size 3 | 128 – 138 mm | 148 – 156 mm |
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.
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: Gas mask Filters are NOT included. Please make sure to choose the appropriate size on the drop-down menu.
