8 Things You Should Know Before Buying a Gas Mask

The driving plot behind some of our best-selling post-apocalyptic fiction novels in America is a looming reality for many people and nations in the world. As droves of Israeli citizens line up at the post office in Israel to pick up their government-issued gas masks, many of us can’t help but ask the depressing question, “Should I buy a gas mask?”

In this article I’ll do my best to clear up many of the questions and myths that surround one of the most iconic symbols of the survivalist movement – the gas mask.

To make an educated decision about whether or not to go on a gas-mask buying spree, you should first consider the following:

 

Surplus does not necessarily mean ‘good deal’

At one point or another, all of us have seen the military “surplus” gas masks advertised online, in catalogs or in Army/Navy retail stores. These masks are “surplus” for a reason. They’re either outdated and have been replaced by more effective models or they are defective. Many of the older surplus masks are famous for being incredibly difficult to deploy and also very ill-fitting even when strapped on correctly. You’ll never find a guarantee of performance on these domestic or imported surplus masks. There’s a reason for that, too. Many of them also ship with filters that are also long expired. I’ll get into that in a later heading. The price of surplus gas masks is enticing, I’ll admit, but the risk is not worth the savings. A good current gas mask that’s up to spec is going to cost at least $125, and more for many models. And that doesn’t include a stock of $40-$50 replacement filters. Surplus gas masks do make great novelties for the man cave, however.

 

Not all gas masks are created equal

Shocker, right? There are certain criteria you need to look for when buying a gas mask. First, make sure the mask and filter is rated for chemical blowing and riot control agents, designated by the CBA/RCA rating, and nuclear, biological and chemical agents, carrying the NBC rating.

Some gas masks on the market are nothing more than glorified surgical masks. While this may be sufficient for most biological threats, it’s also important that any mask and accompanying filter you purchase is certified to protect against nuclear and chemical threats as well. Be sure to discuss this with any supplier before ordering. Third party testing is preferred.

I prefer a mask with filter connections on both sides versus just one side or just in the front. This not only offers more flexibility (i.e. positioning the filter opposite where a gun stock may interfere), but also allows the user to positively attach a replacement filter on the opposite port before removing an expired one.

Field of view is a common frustration with many masks on the market. It’s important to have an unobstructed view during times that warrant the use of a gas mask. Many older surplus masks have small goggle-type eye holes, which virtually eliminate all peripheral vision. How about prescription glasses? It’s important to make sure the mask in consideration accommodates spectacles.

 

You’ll probably need a few spare filters

Not only do filters have a shelf life, but they also don’t last as long while in use as you might imagine. Most need to be replaced after just several hours of use depending on the environment and gas concentrations. Even if breathing in “uninfected air,” they last less than 24 hours. What does this mean? First, it’s not hard to imagine the need for several filters per person depending on exposure times. Second, it’s important to keep track of the expiration date for any filters on hand. At $40-$50 a pop, the cost of replacement filters can add up quick. I would suggest purchasing a mask that accepts 40mm NATO threaded filter canisters. These tend to be the most readily available and popular.

 

Too late is almost always too late

Unless a gas mask is securely deployed before attacks are made, it’s often already too late. Especially in the case of biological and chemical agents, even momentary exposure can be fatal. This begs the question about where you should keep a gas mask. Should it be kept in the home? At work? In the car? Or, should there be one in each location? It’s impossible to predict the time and place that a potential threat may take place. Even if you own a gas mask, a sudden and unexpected attack may not give enough warning to deploy it in time before you have to take your next breath.

Most gas masks don’t play well with facial hair, and I’m not just talking about Duck Dynasty-sized beards either. The 1-week lazy man can be affected. I even have a few female relatives that might have an issue. Any type of facial hair can degrade a critically tight seal against the user’s face. If you’re serious about buying a gas mask, you should also be serious about a clean shave each morning.  NOTE:  Hooded versions of gas masks are manufactured that can be used with beards.

 

You were not born with innate knowledge on using a gas mask

Deploying and strapping on a gas mask isn’t as easy as they make it look in the movies. In fact, many have died by either putting it on incorrectly or not being able to put it on at all while under stress and panic. There are even accounts of people suffocating to death by not removing the plastic seal before screwing on a new filter. I even did this when I installed my first new filter. It’s an easy mistake to make. There is a reason the military conducts gas-mask training exercises. Properly fitting and using a gas mask requires practice. Hands-on training by a professional is preferred. Prior practice at home is an absolute minimum.

 

The United States is a big place

It would be very difficult to cover the entire U.S. with nuclear, biological and chemical agents. Most agree that it is those in the large cities who are in the red zones. A farmer in the middle of Kansas is much less likely to need a gas mask than someone who works in Washington, D.C. This should be considered when making preparedness expenditures. There may be better things to spend a preparedness budget on besides gas masks if you live in areas unlikely to be targeted with nuclear, biological or chemical threats.

 

Gas masks are a means to an end, not the end themselves

You can’t live in a gas mask. They are meant to be a temporary defense for escaping the “green cloud.” If the threat doesn’t stop (i.e. NBC attacks keep coming) and you don’t have a permanent protected place in which to retreat (like an NBC-filtered bunker or safe room), that’s bad news indeed. Even though some gas masks are fitted with drinking straws, it’s just not practical to wear a gas mask for an extended period of time. Gas masks are a short-term solution to hopefully what will be a short-term problem.

Hopefully these insights have helped to “clear the fog” around this somewhat confusing topic. Some reading this article might decide the “surplus” gas mask in the closet purchased online after 9/11 is probably better used as a Halloween costume than a life-saving survival tool. I wouldn’t hold your breath for U.S. government-issued gas masks any time soon. I don’t see that happening in the near future. If you want one, you’re going to have to buy it.

Do you own a gas mask?  Why or why not?

Remember, it’s not if, but when.

Comments

  1. You can test the fit of your mask with smelling salts from a first aid kit.

  2. if your mask won't seal cause of beard growth ad some petroleum jelly. I never had issues with it not sealing but it is gonna pull some whiskers.

  3. Joel Hoffman says:

    rubber and petroleum jelly are a bad idea

  4. Joel Hoffman says:

    good info i have a few of those isreali surplus masks bought after 9/11 andwas just thinking of getting newer NBC masks .perfect timing

  5. Creek Stewart says:

    great tip kevin

  6. Twana says:

    Ironic that this article just popped up on Facebook, as I had just left the Amazon site shopping for gas masks…so this was not only timely, but great guide lines..so good to know..

  7. Can you recommend a specific gas mask?

  8. Tolik says:

    Depends on what you want it for . I have a Soviet GP-5 , the mask is cheap , EASY to deploy and gives you full head protection . I got rid of the Russian canister and replaced it with a modern industrial one . The only thing I want a gas mask for is to make me immune to OC and tear gas ( civil unrest areas ) ………the Soviet mask will do that job , and its cheap . I have a buddy that was a prison guard and deputy marshal after that , he told me that it would indeed be more than enough protection from both those things . Again , depends on what you want it for .

  9. Joel Hoffman yes they are but the newer mask are not 100 % rubber and you should clean it after each use I used the same mask for years only had to replace a couple cracked things on it from abuse on the job. Butt always it worked great

  10. Robert Brooks says:

    I got familiar with the US/GI type gas masks. Glasses are another hassle. Glasses, beards, fogging… Would a hood with full face be more practical for civilians? I suddenly feel really stupid. I don't know squat….

  11. Shepherd says:

    A 3M or Sperian full-face respirator with organic/ acid cartridge and a P100 filter will exceed military standard.[but they won’t explicitly SAY that] McMaster-Carr has the 5541T38 if you want one quick.

  12. Nathaniel Grim says:

    or cover the filter with your hand and inhale, if it suctions to your face, its got a good seal

  13. Elise says:

    Spare filters. Yeah. Don’t know why, but I wouldn’t have thought of that.

  14. I would add that proper fit is crucial. In fact, you should be properly fit-tested annually in any respirator. Trust me, you will regret a bad fit. I had a bad fit once with CS and nearly puked in my mask…not good. If it had been something harmful, like chlorine, sarin or some of the other nasty nerve agents, I would not be writing this now.

  15. Maple says:

    I always emailed this website post page to all my friends,
    because if like to read it afterward my links will too.

  16. Tabitha Martin says:

    I have my Navy MCU2P mask with 1 new filter. Wish i had more filters, but they are a bitch to find…

  17. Tommy Russ says:

    Can you provide any info or advice on smoke protection? I’ve been looking for a mask to double as a smoke hood/protection for the office, plus OC/tear gas/biological/chemical. Thanks, great article!

  18. Suzette says:

    Thanks, great article. The down side is now I need a new mask…lol :o)

  19. Leo Bushnell says:

    Filters don't degrade much if you leave them in their airtight plastic packaging, and it doesn't matter what gas mask you use if it has a good filter and good seal. The filter and the seal are the only variables that affect your lifespan. Some older surplus NBC protection is better than NO protection period.

  20. Survival Pro says:

    I don’t own one. Gas masks are not one-size-fits-all. Depending on make and model, some work better against certain agents than others. Even then, consider the ever-changing nature of biological and chemical weapons. Yes, there are certain standbys, such as anthrax. But just as the flu changes from year-to-year, so can the technology behind these weapons. Government officials may know about the latest strains, but how much does the average prepper know about these things? Yes, some models come with replaceable filters. But compared with other items in a survival kit, these filters have a relatively short shelf life.

    can you recommend masks that will fit kids? i have grandbabies 4,6 and 8. thanks
