Technical Specifications:

With over 450 active nuclear reactors in the world today, it’s prudent to take precautions in case of disaster. 

Featuring cutting-edge engineering and design, the CM-6M gas mask is crafted from bromobutyl rubber with a hypoallergenic inner mask for superior comfort and function. Dual-layer construction helps prevent fogging and makes breathing easy. Equipped with a speech diaphragm ensuring 95% intelligibility of speech, you can communicate with members of your party through the mask.

The included potassium iodide tablets help prevent thyroid damage from fallout and excess radiation, which dissipates up to 200 miles downwind from a nuclear catastrophe. It is advised you take the tablets before or soon after exposure to excessive radiation levels.

The included ThyroSafe™ tablets are the only FDA-approved tablets available in the US—ideal for adults, with a cross-score to provide reduced dosing for children. A single dose of potassium iodide protects the thyroid for about 24 hours—any radioactive iodine taken into the body after dosing is rapidly flushed out. 

The MIRA Safety drop-leg pouch holds the entire kit while mounted out of the way on your leg. Featuring rugged construction designed to withstand abuse without tearing, the pouch comes with a flexible mounting system and padded back for comfort.  

NOTE: The CM-6 mask is one size only. While the 5-point harness provides a flexible fit, the user’s face must be free of facial hair with no obstructions in the way of the sealing gasket. The mask enables the use of a glasses insert (sold separately), which insert into the mask’s rubber slip.

Filters can be fitted to the left or right inhalation chamber. The unused chamber must be sealed with a filter plug. Ensure the filter plug is tightened and screwed into place. Each inhalation chamber is fitted with EN 148-1 standard 40 mmx1/7” thread. Ensure your filters are compatible. 

The effectiveness of the filter depends on the toxins in your environment. The included NBC-77 SOF filter is designed for use in environments with at least 19.5% oxygen (lower oxygen levels will necessitate a SCBA). The filter is designed to offer protection from radioactive particles, viruses, bacteria, gases, vapors and a range of noxious fumes.

  • CM-6M or CM-7M gas mask
  • (20) potassium iodide tablets (65mg)
  • MIRA Safety drop-leg gas mask pouch
  • (1) NBC-77 SOF filter 
  • Canteen

Ask a Question
  • Is this impact resistant?

    Yes, the CM-6M Survival Kit complies with all standards under EN 168 for impact protection, making this the perfect mask for riot control situations.

  • My face dimension is quite small (Forehead 5.90”, Length 7.08” and Chin 4.72”). Will CM-6M fit for me?

    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).

  • I wear prescription eyeglasses, do I have to get a different mask lens or can the mask be worn with my eyeglasses?

    Standard glasses will break the seal of any gas mask. I recommend getting yourself the MIRAVISION Spectacle Kit. It is compatible with both the CM-6M and CM-7M masks. In addition, you can choose different lens types and colors. As part of the order process, we require a current prescription. You can either upload the prescription on the spectacle kit's product page or send it to us via email at support@mirasafety.com.

  • Are these gas mask PAPR compatible?

    Yes! All of our respirators are compatible with our MB-90 PAPR.

  • Is the gas mask pouch that comes with this kit the version 1 or version 2 pouch?

    It is the second version. The first version has been phased out and is no longer in stock.

Gas Mask

Seems to be of high quality. The only real way to tell is a gas chamber, which I'm fresh out of. The fit is great. It seals real good. Easy to adjust. The canteen needs to be cleaned good because of the plastic odor and I'm sure it will have a taste. The fact that it has a drinking tube is fantastic.

Gas Mask Kit

Everything in the kit is of good quality I have only tried on and adjusted the straps hopefully I will not need to use them for their intended use. Trying it on took me back to my days in the Marine Corps. Thank you for making these products and having them available to the public.
