Cm-7M Military Gas Mask-Cbrn Protection Medium
The Mira Safety CM-7M Military Gas Mask in Medium is a full-face CBRN respirator engineered for comprehensive protection against chemical, biological, radiological, and nuclear threats, plus industrial toxic gases, vapors, and aerosols. Designed for users who need dependable defense in contaminated environments—whether for emergency preparedness, tactical training, or hazmat response—the CM-7M combines military-grade filtration capability with practical features that don't sacrifice usability.
This medium-sized mask accommodates most standard adult faces (fitting roughly 95% of the population) and accepts two NATO-standard 40 mm filters, giving you flexibility to choose protection levels matched to your specific threat environment. The design prioritizes both seal integrity and comfort: it features low breathing resistance, a pre-installed hydration system compatible with CamelBak Type M water bladders, sweat drainage through the exhalation chamber, and a high-quality speech diaphragm that allows clear communication with or without communication devices. A negative pressure test—blocking the inhalation valve and taking a deep breath to verify the seal—confirms proper fit before deployment.
The CM-7M's modular compatibility extends its utility: it works with the Scott 804442-01 spectacle kit (sold separately), pairs with optical devices like night-vision goggles, and integrates with helmets and breathing apparatus systems. The drinking system lets you safely hydrate while maintaining a contaminated-area seal, and the straightforward donning and doffing process keeps response times practical.

Frequently Asked Questions
Will the CM-7M fit my face, and how do I know if Medium is right for me?
Medium fits approximately 95% of the population and is the recommended size for average-sized adults. If you weigh 130 lbs or less with a thin face, consider Small; if you're over 250 lbs with a wide face, Large may be better. Confirm your fit by performing a negative pressure test: block the inhalation valve, take a deep breath, and verify that the mask seals tightly to your face without leaking.
What filters does the CM-7M use, and where do I buy them?
The CM-7M accepts two NATO-standard 40 mm filters, which are widely available from many suppliers. Filters are sold separately, allowing you to select the protection level that matches your specific threat environment.
Can I drink water while wearing the CM-7M in a contaminated area?
Yes. The mask includes a pre-installed hydration system that allows safe drinking without breaking the seal. It is also compatible with CamelBak water bladders using a Type M adapter (adapter sold separately).
Is the CM-7M compatible with night-vision goggles and other gear?
Yes. The CM-7M works with night-vision goggles, optical devices, helmets, breathing apparatus systems, and the Scott 804442-01 spectacle kit (sold separately). Its speech diaphragm supports communication devices as well.
