A gas mask is something I have been meaning to add to my preps for quite some time. To be honest, I was at a loss what mask to trust because the price range for a good gas mask is vast.

Would you trust a $50 gas mask from a major online retailer when some mask systems cost as much as $1,000? I concluded that if I was going to invest in something like a gas mask, it would be good to have one that was moderately priced and well designed. Like any piece of gear, my philosophy is that while you don’t want to buy the cheapest one on the market, buying in the high-end range is probably not the best idea either. With most gear and tools you get into diminishing returns for the extra amount you are spending.

Around the time I was thinking about a gas mask, the founder of MIRA Safety approached me about his products. I was lucky enough to get to try out a gas mask they make that has a ton of features I had not considered. My big concern was temporarily being able to breathe during a chemical spill, nuclear incident, or biological attack. While it may sound silly, I had never considered just how important it would be to have the ability to drink water while wearing a gas mask for example.

Gas masks are not just for nuclear incidents. There are many other situations where a gas mask may come in handy. Industrial accidents near your home or business are another example.

The Mira Safety CM-6M mask 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. It is rated to withstand 30 hours of exposure to mustard gas. Let’s hope none of us are ever in that situation.

MIRA Safety CM-6M Tactical Gas Mask – Full-Face Respirator for CBRN Defense

You can actually talk to others when using this mask!

Have you ever wore a civilian respirator or any type of mask?

Do you remember how hard it was for others to understand you?

Matt and I wear respirators more than the average person due to the farm activities we have to do and it is very hard to hear each other speak. The Mira gas mask is designed with a speech diaphragm that makes it a lot easier to hear and understand others. Consider how important this may be during a real emergency.

Since MIRA Safety masks are designed to professional standards, you can enjoy easy communication.

While someone at a distance might not hear what you are saying those that are working with you or within normal conversational distance will understand you without you having to speak up to the point of yelling or anything like that.

You get a canteen and tube for drinking through.

If you prefer a hydration bladder, you can buy an adaptor so you can have a lot of water on hand if desired. The canteen is a decent size but might not be as convenient as a hydration bladder for some applications.

There is not a straw inside of the included canteen so you do have to hold it up and suck a bit to get any water. Inside the mask is a drinking straw that you can use your tongue to get in your mouth when needed.

Since the canteen is smaller, in a real situation you would either want a lot of canteens on hand or a large hydration bladder because chances are you are going to be sweating a lot and that means you will want to make sure to drink a lot of water.

The facepiece is made of bromobutyl rubber

The entire facepiece is made of bromobutyl rubber so you get a very high resistance to a variety of toxic industrial chemicals and chemical warfare agents.

For those that have sensitive skin, you will be pleased to hear that the inner mask is made of a hypo-allergenic material that keeps the mask tight to your face. Since this seals the visor off from exhaled air, you don’t have to worry about your mask fogging up.

I was really happy to see this feature because I have a lot of experience wearing respirators and goggles while spraying crops or doing carpentry work and it is extremely difficult to find a setup that doesn’t eventually fog up. I am so glad that it lived up to the claim.

Filters are not included but you get a discount when purchased with a mask

If you choose to order a gas mask from Mira, make sure to add the filters at the same time you add the mask. With the current pricing structure, this will save you about $20 per filter.

There are different filters available and your mask has space for up to two. The advantage of having two filters is that your mask will be easier to breathe through and it will last longer under a high level of contamination.

You can just use a single filter too and the mask will provide a high level of protection. Having just a single filter allows you to choose what side to put it on which will make it easier to use rifle sights.

The mask and cartridges are effective against the following:

Solid and liquid aerosols, smoke-producing substances, radioactive fallout, bacteria, viruses, vapors of organic and inorganic acids, hydroxides, organic solvents with a boiling point less than 65 degrees Celsius, inorganic acids, hydroxides, ammonia, amines, acid gases, mercury vapors, agricultural chemical combustion products, tear-producing, irritant, choking, blister, and nerve agents e.g. bromoacetone, OC, CR, CS substances, organic compounds of arsenic, phosgene, hydrogen cyanide, cyanogen chloride, mustard gas, organophosphates e.g. sarn, soman, IVA, VX, and other toxic substances e.g benzene, toluene, vinyl chloride, fluorine, hydrogen fluoride, sulfur oxide, phosgene, phosphoric acid and its organic derivatives, chloroacetic acid, nitric acid, nitrogen dioxide, aldehydes, and mixtures of organic and inorganic substances.

The 5-point head harness is super comfortable.

I have long hair and that can cause complications when wearing any headgear. This mask is made so you can take it on and off with ease and it has a built-in hairnet in the back so you don’t pull your hair out or get it ridiculously tangled. During an emergency, it is best to minimize any aggravations like that.

A large and clear viewing area makes this mask stand out.

I am not a big fan of peeping through small eyeholes. I often wear glasses as well so a mask that cannot accommodate glasses is a bit of a problem. I am happy to say that you have a really big viewing area that doesn’t fog up. The large viewing space makes this mask more versatile since any adult can use it.

It can be used in an atmosphere that is at least 19.5% oxygen when used with a filter.

It is important that those that are new to gas masks realize that they have some limitations. They don’t allow you to safely breathe in very low oxygen environments. If you are in a situation where oxygen displacement is a concern, a breathing apparatus must be used. Chlorine gas is one example of a chemical agent that will displace all the oxygen in an area. How long this type of displacement lasts depends on a lot of factors such as wind and how enclosed space is.

The Smoke Bomb Test

We have an old metal tool shed that measures about 8 feet by 10 feet. Recently we cleaned it out because it is getting a bit worn. We have moved this shed several times. In fact, it was the first building we put together up here back in 2008. I bought some smoke bombs and had Matt splice them together and light them while I was in the building.

I could see through the mask and breathe just fine. I am really glad to report that it did not fog up, and I was able to talk to him. The Mira mask costs substantially more than my old 3M respirator unfortunately but that is to be expected for something that offers this level of protection.

If it was comparable in price, I would be very tempted to wear it when spraying grapes because it is exponentially more comfortable and I would not have to worry about a separate set of goggles that are guaranteed to eventually fog up.

The interior is really soft on the skin and there are no unpleasant rubber smells whatsoever.

Save the caps to your filters for storage.

Each filter comes with a screw cap and a fitted protector for the part the air comes in through. I advise keeping these on hand so you can store your mask in a way that keeps debris and such out. Since I opened this just for a test, I definitely took off the filter after testing and replaced the protective caps.

I might go as far as lightly vacuum sealing the filter to offer it further protection until I feel the need to use it again. At $80 per filter, I want to take care of this mask and filter set and not screw it up in storage.

Other masks from Mira Safety

Mira makes several other mask styles and they make gas masks and systems for infants and children so you can have something on hand for everyone in the family in case of a nuclear, biological, or chemical attack. Remember that it is important for a gas mask to fit correctly if it is going to actually protect someone well. An adult gas mask will not work for a child.

MIRA Safety CM-2M Child Gas Mask – Full-Face Protective Respirator for CBRN Defense

The children’s gas masks fit kids from 1.5 -15 years old. You will need to choose between two sizes. A size 1 kid’s gas mask is suitable for children 1.5-6 years old while the size 2 is suitable for those 6-15 years old. Any child under 1.5 years old will need a baby gas mask system.

KZD-6 Protective Enclosure / Infant Gas Mask for Small Children & Pets

The baby and infant system is costly and only offers protection for so long but if you want protection for a child under 18 months or for a small pet, this is what you are going to need. Mira also says it can be used for pets up to 30 lbs or up to two cats.

If a kid is smaller or larger for their age, that may affect what size mask you need to buy. If you happen to get the wrong size, you can return and exchange the mask at no cost.

You can return your mask within 30 days of purchase if you are not comfortable with it but I think you will like the quality and comfort. I just like to let folks know when a company stands behind their products because survival gear is not a small investment. Mira also offers a 5-year warranty on all their products and excellent customer service.

MIRA Safety CM-7M Military Gas Mask – CBRN Protection Military Special Forces, Police Squads, and Rescue Teams

This mask is constructed similarly to the mask I tested, but it is made to be more easily used with optics such as night vision goggles. If you plan on using any type of advanced optics, you may want to consider getting this version. Personally, I prefer the mask design I tested because I like a big viewing window.

At the same time, I know that using binoculars and such would be more challenging. There is a minuscule price difference between the two masks so cost should not be a factor in your decision as to what style to buy.

If you have a gas mask, practice with it and know how to use all of its features.

This is the first gas mask I have ever worn and after testing it out I would advise anyone that adds a gas mask to their preps to thoroughly review how to use it, the specs, and the limitations. It took me a while to get the mask adjusted to my head and face. I also had to learn how to use the drinking straw. Getting a good seal on your mask is critical and you will need to be able to do that fast if you are every in a real chemical or nuclear situation. You do not want to be fumbling around.

Final Thoughts

I am impressed with the comfort and quality of Mira products. If you are looking for a well-made gas mask, then I advise giving them a try. I stand by what I said before about not trusting gas masks with too good to be true pricing. While something may work briefly or provide some protection, do you really want to trust cheap gas mask manufacturers with your life and your long-term health? What about the health of your family?

  1. Goodmorning everyone
    we are a group of Italian preppers
    do you have a reference where you can buy fitri in europe?
    Thanks Alpha5819

  2. May be good quality, way over priced. No one does NBC better than the Israeli’s. Look for New or surplus masks on Amazon, ebay, or internet sources. Filters are military grade for a low cost. Best way to go.

  3. Excellent review! Thank you for being so thorough. If anyone reading has questions about MIRA Safety product, feel free to reply to this message. Being the founder, I know a thing or two about the product lineup 🙂

  4. i wore masks for many years as an industrial painter, spraying some real nasty stuff. if you google the content of air you find out that air contains only 20.95 % oxygen , so if the air you choose to breathe has to contain “at least 19.5% oxygen” it would be completely worthless in say a smoke filled room where a smoke grenade had been introduced, you also listed several items that the filters will filter out multiple times, repeating yourself in the list of items more than 1 time.
    even the cheep Israeli surplus gas masks come with a drinking tube that has a straw to be inserted into your drink holder, having to turn a cheep plastic canteen upside down in order to get a drink is crazy! the price of filters are more expensive than brand new usa government filters and current issue surplus filters too. many other items in your article make me believe that you received a value of $ greater than 1 mask and say 10 new filters to advertise their product to your audience! the whole article stinks of paid advertising in my opinion, and im now 61 years old and remember way back around 1972 when i bought my first “survival book” feasting free on wild edibles by bradford angier. i even a staph A infection when brought into emergency room in a comma during a blizzard while my doctor didnt even think i would live threw the night! and also survived 10 years in american prisons where i was a MAN 24/7/365!!
    so to be even 1/2 way credible you need to divulge to your readers if you have received compensation from the maker/ seller of any item you review in the future.

  5. I wear and fight regularly in a mask. The wide field of view is a real good thing.
    Make sure you shoot in it. You may have to tilt the rifle.
    Exercise with it on to test the seal and your cardio. Know limitations.
    Go into a chemical environment expose yourself then put it on, clear it and start breathing. That way if your exposed first you know how and don’t panic.
    I use mine for skunk removal too.

  6. Having worn SCBA gear in the fire service I am a bit familiar with the concepts behind masks. I found some Czechoslovakian surplus masks that I use for quite a few tasks that require them, but NOT for fire service use! These masks have two filters that fit in the cheeks, inside the mask which eliminates the bulky filter on the outside. These also come with drinking tubes, and at around $13 ea. don’t kill the budget. Extra filters can be obtained for them too. Granted, they are not the fanciest or best on the market, but for those on a tight budget they are better than nothing.

    • Yes, a kind of Soviet era copy of the Vietnam war gas mask, M17. Cheek filters are obsolete and difficult to change (you have to remove the mask, others not). Filters are expired and could have asbestos (to be confirmed), and at the most are useful against some nasty odors or dust. Good for reenactment, steampunk, fancy, fetish or gothic or apocalyptic shots. On low budget, better to get some Chinese high duty masks (not the cheap ones you find on the bay etc.). they have pretty good ones, since they have firefighters equipment needed, and very toxic industrial environment in industry. They have a copy of GP5, nut with the universal thread, and a good military grade gasmask, masks with twin or three filters etc. The other high grade gas mask, expensive, is the new Draeger military mask. Forget Mestel, clone of a full face diving mask, too expensive. 3M does make a pretty good panoramic respirator, but very expensive; other full face and half face are of lower quality than the masks they did 20 years ago …
      And for bugging out, quite different that the firefighters, rescue, industrial field, think how much bulky the modern designs can be in your bag (panoramic, hemispheric visors etc.) I understand Samantha loves the Mira design. A good 2 visors foldable mask gets into a pouch, a little bag, in your car, etc. and yes the Mira/czech masks get twin filters, heavier but longer filtration allowed (they have a 7 filters systems with the NBC suit in the Czech products line).

  7. Great article on MIRA masks, but how much do they cost and where can we find them. I live out in the sticks and my nearest Cabelas is 60 miles away. Thanks.

    • You can find MIRA masks by clicking the links above, Dan. MIRA Safety offers free shipping anywhere in the U.S.

  8. Congratulations! One of the most (and so rare) review about using a gas mask, with all the + and minus, and hings you dont think of ! A comprehensive review. Just two points. three rather.
    1) a suit or protective gear is a most in some situations, not speaking or nerve gas, but as for volcanic ash, fall out, or any pesticide or chemical spill or leakage. and mask goes under the hooded suit. the brand make (but it is professional rated and rather expensive) one of the best hazmat suit sold in the world.
    2) Practice and training, yes, and be able to stand the mask for hours or in a messy stressing environment. there is a video on YT , Norway, where girls and guys train running / climbing in woods and hills, with S10 masks. Exhausted.
    3) Mira makes NOTHING. It is just for US a reseller of the Czech made gear, And yes, they are well known and used in East Europe, the brand has a long long experience of masks before WWII, during the cold war, and today. Check their site (but I think they does not sell directly to Northern America, why Mira)
    Congratulations again Samantha and please keep in touch !

    • Thanks for the comment, Anita. MIRA Safety is actually the retail arm of GuZu. We work side by side with GuZu to release military-grade products to the North, Central, and South American civil defense markets. Just FYI…we have a new mask coming out in the next few months that will be a wide-visor version of the CM-7M. Stay tuned!
