The CM-7M military gas mask is the ultimate chemical, biological, radiological, and nuclear (CBRN) defense system when used in conjunction with suitable filters or a breathing apparatus.
The military-grade technology used for this full-face respirator provides comprehensive protection against the full spectrum of CBRN agents and toxic industrial chemicals in the form of gases, vapors, and aerosols.
Small: 5.19-5.51 inches
Medium: 5.51-5.82 inches
Large: 5.82-6.14 inches
To size yourself, it would require a device called a faciometer which is not very common.
Medium fits 95% of the population, so if you’re an average size person, we would suggest medium. For smaller than average people who weigh 130lb or less, with thin faces, we would suggest 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: Filters are NOT included. Please make sure to choose the appropriate size on the drop-down menu.
