This premium-quality full-face respirator, in combination with a suitable gas filter or breathing apparatus, protects the face and internal organs from the harmful or even lethal effects of Chemical Warfare Agents (CWA) and other CBRN agents that come in the form of gas, vapor, aerosol, or radioactive dust-based toxins.

The facepiece is made of bromobutyl rubber with a high-level resistance against TIC/CWA penetration. The inner mask is made of a special hypoallergenic compound which ensures excellent tightness and avoids contact of the exhaled air with the visor and thereby protects it from fogging. It also reduces the CO2 content in the inner space of the mask, which together with its favorable rate of inhalation/exhalation breathing resistances decreases the physiological burden of the user.

The speech diaphragm ensures at least 95% intelligibility of speech. The mask is equipped with a five-point rubber-textile head harness.

The CM-6 mask is produced in one size. For the proper function of the mask, it is necessary that the user’s face is smooth, free of facial hair, sideboards and other hindrances in the place of the sealing gasket. The mask enables the use of dioptric glasses in a spectacle insertion fixed in the rubber slip in the upper inner part of the facepiece (above the visor). Spectacles have to be ordered separately. (They are not a standard part of the mask.)

The filter is fitted to the mask by screwing to the left or right inhalation chamber. The unused chamber (without filter) is sealed with the inhalation chamber plug. It is necessary to check whether the plug is well screwed and tightened. Inhalation chambers of the CM-6 mask are fitted with Rd 40x1/7“ thread according to the EN 148-1 standard.

Before use, the user must verify whether the filter thread (or breathing apparatus) type is compatible with the inhalation chamber thread.

Selection of a suitable filter depends on the type and concentration of the toxic agent. The CM-6 mask equipped with a TIC or CWA filter may only be used in an environment containing at least 19.5% oxygen. If the oxygen content is lower, a breathing apparatus must be used instead of a filter. The principles of filter selection and application are described in the filter user guides.

The CM-6 mask may be used in class 1 explosive environments only. The CM-6 mask meets all of the requirements for class 3 of the EN 136 standard.

The CM-6 masks must be stored in a dark, cool, and dust-free place free from sudden temperature changes. The storage room should be ventilated regularly. Temperatures may vary between 10°C and 25°C within relative humidity up to 65%. The stored products may not be exposed to radiant heat and sunshine. Fuels, solvents, lubricants, and other inflammable substances, including chemicals, must not be stored together with masks. Moreover, there may not be any electric machines or appliances that produce electric sparks and discharges during their operation (ozone creation).

Avoid any deformations of the rubber parts of the facepiece and internal mask when storing the masks.

"THANK YOU MIRA!" Our family LOVES our MIRA CM-6M GAS MASKS!!! The construction is superior, the quality of the materials is very high grade, and the workmanship is superb. We highly recommend this gas mask to all who care about their ability to breath when the air won't allow it.

Insurance for disaster - Amazon Review

This gas mask is really high quality and you get what you pay for. I started off with an Israeli mask I picked up for 40 bucks and decided to upgrade after noticing that there are small cracks in the rubber. Did some research on this, and it seems like most Israeli masks sit around for many years, and after they expire, are sold at surplus auctions for pennies on the dollar...eventually ending up on Amazon and sold at enormous markups. This is the type of thing that's likely going to sit around in my closet for many years to come, so I'd rather get something that would actually work if a true emergency happens.


Best bang for your buck CBRN mask - Amazon Review

I’m an Army combat veteran with 4 tours in Iraq, and somewhat of a gas mask collector. Within my collection, I own the following: - MIRA Safety CM-6M - Drager CDR 4500 - Drager X-plore 6300 - 4A1 Israeli Civilian Mask - Israeli Military M15 Mask - Mestel SGE 150 - Mestel SGE 400/3 I originally wrote a version of this review for a Drager mask I purchased and it got a lot of helpful votes, so I figured I’d expand on it and go into detail about the MIRA CM-6M, while giving some background about the other masks I own. Considering the many options, it’s important to know what the mask is intended for, and the level of protection it offers. Keep in mind, the focus of this comparison is for CBRN applications (chemical, biological, radiological, nuclear). Also keep in mind, that a gas mask is only one component of CBRN PPE (personal protective equipment). To minimize exposure during a true SHTF scenario, you also need coveralls, gloves, boots, and Chemtape to seal up the seams. Along with that, you would need a decontamination agent such as FAST Act for equipment, and RSDL for skin. -- MIRA Safety CM-6M: PROS *Compliant under EN 136 CL3 standards for respiratory protective devices. *Large visor with a very wide field of view. *Made from butyl rubber which meets material specifications for CBRN protection. *Comes standard with a speech diaphragm. *Comes standard with a pre-installed drinking system and external canteen. *Compatible with CamelBak water bladders. *Fits standard 40mm filter cartridges, which are widely available. *Fits up to 2 filter cartridges simultaneously, increasing the time you can go without changing filters, and making it easier to breathe under physical exertion, or for people with smaller lung capacities (kids). *Used by military in Europe and the Middle East. *Long shelf life of 20 years. CONS *Has a slight rubber smell. In all fairness, all butyl masks that I own also have some rubber smell, just figured I’d mention it just in case someone reading is very sensitive to this. *It’s not NIOSH CBRN Approved so it would limit professional use in the USA (Most government agencies require NIOSH CBRN approval for respiratory devices as part of OSHA standards if using the mask as part of your workplace PPE). Definitely great to have, but having or not having this certification does not determine quality, just means it went through and passed a certain series of tests here in the US. --- Drager CDR 4500: Fantastic all around mask that I have now designated as a preparedness backup after my CM-6M and DHS 7000. The lack of a drinking system made me seek out other options as gas masks get pretty stuffy, and taking off the mask for some water while getting out of dodge may not be an option. Drager X-plore 6300: The structure of this mask is identical to the CDR 4500, with some slight color variation. The major difference is the rubber used for this mask is not NIOSH CBRN approved. However, It does have a NIOSH rating for use against many gases, chemical agents, and particulates. This mask holds an EN 136 CL 2 certification. 4A1 Israeli Civilian Mask: Sold mostly in surplus stores and can be picked up for under $30. Visibility is poor considering the small visors, one for each eye. Many people in Israel have this mask in case of emergency, and I’m sure it’s saved lives over the years, but I would not trust it considering most are surplus and could have been sitting around for 20+ years. This mask is not rated for CBRN purposes. Also, do not use the supplied filter as most are long expired. Israeli Military M15 Mask: Similar specs to the 4A1, but with bigger visors. These do expire (20 yr life), so keep that in mind if purchasing. I’ve owned 5 M15 surplus masks over the years and 3 had damaged valves, leading to a return. These masks are resistant to certain warfare agents, but not the full gamut. I would recommend looking up the spec sheet for more detail. Mestel SGE 150: This mask looks really nice, but is not intended for CBRN purposes of any sort. There is no coating on the visor against chemical irritants, and there is no CBRN certification. Primary use for this would be against tear gas, pepper spray, and riot situations. Mestel SGE 400/3: Same as the SGE 150, but with 3 filter ports instead of one. This mask also has a few optional accessories. Retail is around $200, and can cost upwards of $400 when fully loaded with accessories (speech diaphragm, drinking module, canteen). If you want the extra accessories, you either have to buy it pre-installed, or send it back to the factory for professional installation which could take weeks. This is a great mask to block tear gas if you’re stuck in a riot, but is not intended for CBRN applications.

Great product and service

I made an order for CM-6M mask and paid for "USPS Priority Mail Express International shipping" which is 66$ which on MIRA's site and USPS site says takes 3-5 days. As 14days passed I got upset and saw on USPS tracking site that it said "First-Class Package International Service", then I emailed MIRA about my problem. They quickly replied, appologized and sent me a screenshot of their payment to USPS that was 69.61$, they also said they will try and contact USPS, since the problem was clearly on USPS, and send me a refund for shipping if they confirm their mistake. Shortly after some days they emailed me again saying USPS didn't reach back to them yet, and regardless issued a refund of 44$ back to my paypal account, which then amounts to me paying for around the price for "First-Class Package International Service". The package arrived a day later of the refund. Gotta say the mask is great, drinking system works nice, harnesses are easily adjustable, visor is sturdy, gives a great view and doesn't fog, the mask material seems high quality in my hand and fits on my face as it should despite of beard giving me a proper seal. Didn't test it with filters yet, but overall great product, I was also very pleased with the refund and their quick responses.
