Food and water are not the only things you need to prepare for your survival. If you really want to be prepared, you need to invest in the best gas mask in case, you know, someone starts a war or there’s a chemical attack in your area.
But here’s the problem:
Buying a gas mask isn’t easy. Not a lot of people have a clear idea of what to look for so it’s easy to make mistakes.
If you are one of those people, here’s an in-depth guide you can use to find the best gas mask for you.
A Brief History
Believe it or not, gas masks aren’t considered a type of modern device. Their history goes back several centuries ago.
History suggests that the ancient Greeks used some form of gas mask back then. In particular, they used sea sponges to filter noxious air and harmful dust.
There was nothing complicated about them. In fact, they were just plain sponges.
In the 9th century, the first well-documented use of gas masks was recorded. It happened in Persia where people who were working on polluted wells wore gas masks to protect themselves.
In over 900 years, there was no update or stories about gas masks. It was only in the late 1700s that they got an upgrade. Jean-François Pilâtre, a French inventor, created the first respirator.
From there, gas masks continued to change and evolve. By 1828, John and Charles Deane created a smoke-protecting apparatus. Designed for firefighters, it worked by pumping air into a helmet, allowing the wearer to enter burning stables and rescue horses and other animals.
In 1847, charcoal was added to gas masks. It’s highly absorbent which means that molecules, ions, and atoms from other substances adhere to its surface. It’s different from absorption where a type of fluid gets dissolved by a liquid or solid.
The most important changes in gas masks probably happened during World War I. There, people used different industrial technology to cause harm to others. That included the use of poisonous gas.
The use of such a method required both sides to create reliable gas masks to protect themselves. And because of such need, gas masks improved dramatically in terms of reliability, quality, and durability.
Believe it or not, these approved gas masks aren’t just needed to survive the end of the world.
It’s one of those things you wouldn’t want to be without in case something happens and you’re unable to breathe because there are chemicals in the air. Obviously, if you can’t breathe, there’s a good chance you could die.
Apart from that, you should also consider having a gas mask for the following reasons:
- To Protect Your Lungs
The chemicals used in chemical warfare don’t just create problems for the skin and eyes. Their actual power is in their ability to stop humans from breathing.
With reliable and approved gas masks, you’ll be able to have respiratory protection. It’ll stop the gasses from reaching your system and causing problems.
Approved gas masks are also helpful when there are wildfires. They can produce huge amounts of smoke and exposure to them can cause a wide range of respiratory issues.
- To Protect Your Eyes
In chemical warfare, your lungs aren’t the only organ that’s at risk. Exposure to harmful chemicals can also leave permanent damages to your eyes.
And when you’re caught in the middle of chemical warfare, you’d want to keep your vision intact. Without the ability to see, you’ll have problems getting yourself to safety.
- To Protect Against Illnesses
In the middle of a pandemic, you’d want to have a gas mask on hand as protective equipment. It can help guard your lungs and eyes by preventing bacteria and other microorganisms from entering your body.
But here’s the thing:
A gas mask can only offer respiratory protection to a certain extent. It has no way of killing viruses.
- To Protect Yourself Against Smoke Inhalation
There’s nothing wrong with focusing and preparing for large-scale disasters. However, if you really want to be prepared, you also have to consider common emergencies like a house fire.
If you were caught in that kind of emergency, you’d find it easier to escape if you had a gas mask, right? It’ll make it easy for you to breathe as you move to a safer location.
- To Protect Yourself During a Nuclear Fallout
This one’s a bit extreme. However, to be fully prepared, you need to consider all emergencies and that includes a nuclear explosion.
With a gas mask, you’ll be able to avoid breathing in the fallout. It will help keep you safe from the detrimental effects of poisoning.
- To Protect Yourself During Civil Unrest
Peaceful protests are quite common these days. However, no matter how hard protesters try to keep them peaceful, there’s still a good chance that they can turn violent. They may even trigger conflicts with the local authorities which can put your safety at risk.
How Do Gas Masks Work?
In general, approved gas masks offer protection against noxious contaminants. The way they do it can vary but their basic purpose is to filter out harmful particles and substances while letting clean, breathable air in.
Depending on the design, gas masks may also protect the eyes and other vulnerable tissues on the face.
Although gas masks are a big help during warfare and riot control, it’s not always effective.
For one, they are not capable of providing protection against chemical agents that can get into your system through the skin. Examples of these agents include mustard gas and sarin.
They can’t offer protection in a fire, too. The only thing they can help you with is in filtering out soot and keeping smoke out of your lungs and eyes.
Now, let’s talk about filters.
Air filters that are used with approved gas masks work by using any one or a combination of the three different air purifying techniques:
- Chemical reaction to neutralize chemicals
- Particle filtration
- Chemical absorption
Out of the three air purifying techniques, particle filtration is the simplest. When you place a cloth over your mouth to prevent dust from getting into your lungs, you’re using this technique.
In the event that you have to deal with a potential biological threat, you’ll need a fine particulate filter.
Think about this:
Anthrax bacteria have a minimum size of about one micron.
Considering that, you need a filter that can remove bacteria of that size. Fortunately, the majority of today’s biological particulate filters can remove particle sizes that are as small as 0.3 microns.
There are chemicals that can’t be removed by particle filtration. This includes chemicals that come as vapors and mists.
For these kinds of chemicals, chemical adsorption or absorption is the best technique to use.
For organic chemicals like paint fumes, activated charcoal is the most ideal agent. It works really well at trapping organic chemicals or carbon-based impurities.
For the third technique, consider the gas attacks that happened during World War I. Back then, armies used masks designed with chemicals that are known to neutralize chlorine.
In modern times, you have the option to pick from different filters based on the chemicals you wouldn’t want to be exposed to. The NIOSH or the National Institute for Occupational Safety & Health color code filters for chemicals.
For example, if you want protection against radioactive materials, you’ll need to find a purple or magenta filter. For protection from smoke coming from burning buildings and wildfires, consider getting a filter that works against particulate matter.
Understanding the Parts of A Gas Mask
For you to have a better understanding of approved gas masks, you need to take a good look at their parts. That way, you’ll be able to know why each piece is critical to a mask’s purpose.
The Face Cover
Considered the biggest piece of a gas mask, the face cover generally holds all the different pieces together. It’s typically made of silicon rubber.
The said material is highly resistant to high temperatures. Plus, it’s really flexible, too.
For them to filter air, different filters are used. The most common of them is the activated carbon.
Their main purpose is to keep the mask in place. They can keep it stable even in the event of sudden movement.
In addition to vision, the eyepieces also provide protection from gases, debris, and heat which can be very damaging to the delicate organ.
Usually, eyepieces are made with polycarbonate plastic. This material is waterproof and resistant to high temperatures. They also offer a certain level of shade to minimize flashes.
How to Wear A Gas Mask
Your gas mask won’t be able to protect you if it doesn’t fit properly. In wearing one, you have to remember that you need it to create a vacuum seal with your face.
How do you do that?
- Complete loosen the straps and pull them to the front of your maks. By doing this, you’re getting them out of the way.
- Next, put your chin in the chin cup and carefully roll the mask on your face. As you wear it, ensure that your nose is in the mask’s nose cup, too.
- Hold the mask in place and pull the straps to the back of your head.
- Once you’re sure you have a nice fit, you can start tightening each strap. Make sure that the mask is secure before working on the middle and bottom straps.
- With your hands, cover the filters and inhale deep and fast. This is to check the seal of your mask. If you feel that it’s tightening around your face and there’s no air getting inside, then your fit is good. Otherwise, you’ll need to repeat the process until you’re able to create a vacuum seal.
When putting on your mask, you have to remember that if it doesn’t fit properly or if you don’t know the right way to put it on, there’s a good chance that it can’t offer protection. This is why it’s a good idea to practice donning and doffing a couple of times until you get the process right.
Note: Don’t wait for an emergency before trying on putting the mask on and taking it off.
Consider getting several filters, too. When it comes to gas masks, there’s no such thing as too many filters. Be sure to keep a selection of them based on the emergencies you’re preparing for.
Common Mistakes When Buying Gas Masks
If you’re new to buying gas masks, it’s easy to make mistakes. However, since these masks are critical to your safety and survival, you need to find a way to make sure you get your hands only on the right mask for you.
Below is a list of the common mistakes people make when buying gas masks and how to avoid them:
1. Purchasing Obsolete Masks
Like with any product, the shelf life of gas masks is limited. They deteriorate when they get old, making them ineffective in protecting you.
So how do you spot obsolete masks?
If they are sold at an incredibly low price, there’s a good chance that their quality is questionable. Also, if you see cracking, tears, and changes to its appearance, they probably offer little to no protection.
To give you an idea, take a look at some of the masks you’d find in the surplus condition below:
Serbian M1 Gas Mask
This was widely used by the Iraq army during the Gulf War. Designed after the old M9 American gas mask, you may even find chromium in its filter. Extended exposure to this can increase the likelihood of getting contract cancer.
Canadian C-3 Protective Mask
This one is considered the predecessor of the Canadian C-4 mask. It’s been out of production in the last 30 years but you can still find it on several military websites. It comes with 60mm threaded filters which is a huge challenge to find in good and new condition.
GP-5 Gas Mask
This Russian gas mask is totally outdated. In fact, its production ended sometime in 1990.
Czech M-10-M Protective Mask
You won’t find this mask useful for CBRN protection. It’s outdated and if you find one, you won’t be sure if it’ll still work.
M17 Gas Mask
2. Buying Improper Filters
Like obsolete gas masks, expired filters offer zero protection. Even if you change them frequently, they probably won’t be able to ensure your safety from contaminants and other noxious substances.
If you are going to buy a gas mask, make sure that you have enough supply of proper replacement filters. And most importantly, keep them in a place where they won’t be exposed to air, sunlight, and humidity.
3. Buying a Badly Fitted Mask
One of the most common reasons for a bad fit is buying an incorrect mask size. You see, there’s no such thing as a one-size-fits-all mask.
In general, masks come in three sizes: small, medium, and large. Picking the right size for you can be quite tricky.
Here’s a rule you can follow:
In finding the right size of gas mask, consider the one that’ll allow you to put it on fast and comfortably.
Gas mask sizes aren’t really that different from the sizes of your other headgears such as your hats. You can use them as a reference or you can just refer to the size variations manufacturers offer with the masks they make.
If you’re a big guy, consider buying a large-sized gas mask. This will allow you to put it on your head without any pressing sensation. Apart from that, a big size will also help you see better since it has a wider viewing area.
Medium-sized masks are a bit tricky. They can be bigger or smaller depending on the sizing metrics manufacturers use.
For those who are below the average height and weight, it’s good to go for small-sized gas masks. They shouldn’t be too tight that they press hard against your head, ear, or neck.
Things to Consider When Looking for The Best Gas Masks
Having the right gas mask is critical for survival, particularly when you’re exposed to seriously deadly airborne contaminants. Because of this, you have to be extra careful when buying your mask for the first time. You need to make sure that it offers maximum protection.
With that, here are some of the most important things you should look out for:
1. The Right Fit
As mentioned earlier, a gas mask will only be able to protect you if it fits securely to your face. One way to ensure a good fit is to buy a mask with adjustable straps. This way, you can loosen or tighten them to get a really airtight fit.
You may also want to look for a gas mask that comes with a comfortable seal. This is helpful when you’re doing physical activities like shooting or running.
There are also masks designed with filter connection points on both sides. These masks are good because they offer more flexibility. They let wearers attach new filters before taking out the used ones.
2. Proper Rating
Find a mask and filter that have a nuclear, biological, and chemical rating. It’s also a good idea to invest in a mast that’s rated for chemical blowing and riot control agents.
Once you have them, make sure to get enough replacement filters, too. Keep them in a cool, dry place that’s away from humidity and sunlight exposure.
3. Up-to-Date Masks
When buying gas masks, you have to be careful about some military surplus models. Some people sell them at a really low price, making them look like a great deal.
Unfortunately, some of them are defective and outdated. They may have been kept in storage for several years so there’s a chance that they’re way over their expiration date.
Buying these masks isn’t safe. Remember, a gas mask’s materials can degrade over time. This can make them permeable to toxic materials and particles.
4. Additional Features
If you wear glasses, it’s a good idea to buy a mask with corrective vision compatibility.
There are also masks with hydration ports that let the wearer connect tubes to a compatible water bladder. This feature is helpful in staying hydrated without the need to remove the mask.
How to Store Gas Masks
Ideally, you need to keep your mask and filter in a cool, dry place. It should be clean and not exposed to extreme temperatures. It’s also a good idea to store your mask in an air-tight container.
What if you’ve already used your gas mask?
You have about 24 hours to use it before you need to change its filter canister. Take note that if the air is too saturated with particles and chemicals, you shouldn’t wait for 24 hours before replacing it.
How Are Gas Masks Rated?
Government agencies set up rating systems to make sure that gas mask manufacturers are able to keep comply with the standards. The most important ratings you need to know are the following:
This symbol stands for Conformité Européenne (European Conformity). Every product in the EEA or European Economic Area must have this mark.
This indicates that a certain product meets all environmental, health, and safety protection requirements.
Masks marked with this meet the requirements that allow it to be used as a part of respiratory protective devices in systems with negative pressure.
As mentioned, the NIOSH or National Institute for Occupational Safety and Health sets the standards for gas masks for US professionals. Having the approval means that masks have met the standards for protection against CBRN agents and other contaminants you may be exposed to in the field.
Gas Masks vs Respirators: How Are They Different?
Gas masks and respirators are basically not the same things.
Gas masks are considered protective masks. They cover a person’s face and protect it against hazardous and poisonous chemicals and gases.
They usually use activated carbon as their main filtering technology. Although it’s effective, its use is quite limited as it can only remove certain chemicals.
And here’s an important thing to remember:
Once the charcoal is full, it has this tendency to release its captured chemicals.
With this, it’s safe to say that gas masks can only be effective if the correct filter or cartridge is used. Plus, they require frequent replacements to remain effective.
Respirators, on the other hand, are particularly designed to filter out particles in the air as you breathe. Basically, it’s effective in dealing with just particles and not vapors, gases, and chemicals.
There are two main types of respirators:
These respirators offer protection by cleaning and filtering contaminants from the air. One of its common examples is the particulate respirator.
This kind is inexpensive since it’s simple. Its main purpose is to protect you from airborne particles like a surgical face mask.
Another good example is the full-face gas mask respirator. This one uses a filter cartridge to filter chemical gases and particulates in the air. As you inhale, the filter cleans the air that goes in.
They have a separate source of uncontaminated air which they supply to the wearer.
Its most common example is the SCBA or the self-contained breathing apparatus. It has its own supply of compressed clean air so there’s no need to use filters.
Another one is the air-supplied respirator which utilizes an airline hose to provide clean air. Usually, it’s used by workers who need to work in a dangerous location for an extended period of time.
Now, which one do you need?
The answer to that question will depend on you and your purpose in getting a gas mask.
Choose based on your location and exposure. You should also pick based on your appearance and style.
For example, if you have a beard, you may want to get a hood-style gas mask. With it, you won’t have to shave to get an effective seal.
Where to Buy A Gas Mask
However, if you do a bit more research, you’ll be able to find more shops that sell a wide variety of gas masks. You can even find some of them in your area.
Before you buy gas masks, you need to know the exact model you need. You can determine this by identifying your purpose.
This extra step is useful when buying gas masks online. With so many varieties, you may end up feeling overwhelmed and confused.
Understanding Gas Mask Filters
Respiratory filters are marked with a standard color coding. This is widely used in Europe as required by the EN 14387 standard.
With color codes, you should be able to recognize what kind of protection a certain filter provides.
For example, a filter marked with “K” and a green color code offers protection against organic ammonia derivatives. An ABEK filter that’s color-coded with brown-grey-yellow-green, meanwhile, offers protection against vapors and gases of both organic and inorganic compounds. It can also protect you from hydrogen chloride, sulfur dioxide, and organic ammonia derivatives.
A gas mask filter’s shelf life can range anywhere between 5 to 10 years. However, high-end models can last longer. With proper storage, they can last for 25 years or even longer.

Frequently Asked Questions
How Long Can A Gas Mask Protect You Once You Have It On?
Can A Gas Mask Help You Breathe When There’s Not Enough Oxygen Around?
The answer is NO. A gas mask only helps filter contaminants and particles in the air. They don’t provide oxygen unless you have an SCBA system. Without enough oxygen, you may suffocate.
Are Gas Masks For Everyone?
Technically, the answer is yes. However, some people may have a hard time breathing with a gas mask on. This commonly happens with people diagnosed with breathing problems and those who have existing lung diseases.
