Best Survival Gas Masks (& Filters) On The Market

By Will Brendza | Last Updated: March 1, 2023

Gas Mask And Several FiltersOh, the iconic gas mask.

The piece of survival gear that’s always associated with chaos, war, terror, and mass destruction.

Its image conjures up thoughts and feelings of spine-chilling events.

Disasters where the very air we breathe is not safe.

Where the air is poison.

And that’s exactly why you need one. Because the United States and Russia are NOT on a peaceful trajectory. 

But that’s not all gas masks are for…

They are also necessary for many DIY projects. They can protect from paint fumes, chemical vapors, demolition debris, etc.

You should always avoid breathing toxins, which is another great reason to keep a gas mask handy.

But gas masks are expensive. Some cost several hundred dollars just for the mask – filters are sold separately!

That’s why I’ve made it my mission to find the most affordable, high-quality gas masks on the market today.

Proven ones that won’t break the bank.

So today, we’ll be focusing on the following topics:

Gas Masks For Kids

When it comes to fitting your children, your options are extremely limited.

However, over the past few years, there has been a renewed focus on protecting children.

A couple of new gas masks for kids have recently been brought to the market.

Your first choice (and best choice IMO) is the:

CM-2M KIDS Tactical Gas Mask

The CM-2M KIDS Tactical Gas Mask is one of the only full-faced CBRN rating defense gas masks for kids.

It fits kids from 1.5 years to 15 years old - after that, they usually fit adult-sized gas masks.

The CM-2M Children’s Mask is available in 2 sizes:

  • Size 1: Kids 1.5 to 6 years-old
  • Size 2: Kids 6 to 15 years-old

It even comes with a standard speech diaphragm and is made for CBRN defense and emergency preparedness.

CM-3M CBRN Child Escape Respirator

Here we have the CM-3M CBRN Child Escape Respirator.

This expandable hood respirator deploys in a matter of seconds and can provide hours of protection for some of the youngest members of your family.

Most modern gas masks are designed for military use. But the CM-3M Child Escape Respirator is designed for small children and young teenagers.

Because children have substantially less lung capacity than adults due to their smaller size. Meaning they can struggle to draw enough air through the complex filters in today’s gas masks.

So instead of wrestling with ill-fitting kids' face masks and straps, this unit can simply be expanded and placed over the child’s head.

Once the blower is activated, the mask will overpressurize—simultaneously ensuring the child can breathe easily and providing a natural protective barrier to keep out aerosols and dangerous threats like mustard gas.

The solution is as simple as it is robust: powered by household CR123 batteries and using standard 40 mm NATO filter cartridges.

We earn a commission if you make a purchase, at no additional cost to you.
KZD6 Enclosure / Infant Gas Mask

This KZD6 Enclosure / Infant Gas Mask is the only solution I know of for children too young for a child’s gas mask (under 18 months) or small pets.

This protective enclosure seals hermetically. Thus it provides life-saving protection from toxic contaminants, bacterial agents, and dangerous radioactive exposures.

The KZD6 is the only protective solution of its kind and is designed to protect babies and small animals:

  • Children – Up to 18 months
  • Pets – Less than 30 lb

Why Everyone Should Own A Gas Mask

In my opinion, too many survival articles begin by pointing out that water is the number one survival priority but it’s not.

I’m NOT saying that clean water isn’t essential for survival (it is), but it’s secondary to air.

Access to clean, abundant, breathable air trumps water every single time.

Why? Because while it’s a well-established fact you can only survive 3 days without water (less time in intense heat), you can only survive a few MINUTES without oxygen (and you’ll go unconscious well before that).

Most of us take clean breathable air for granted…which can be a deadly mistake.

But you might argue that “air won’t just vanish” and you’d be right. Our entire atmosphere won’t instantly vanish.

However, just because air is breathable doesn’t mean it’s not deadly.

It’s possible to breathe highly toxic chemically infused air. The sort of air where even a few small gulps and you’re headed for an early grave.

Of course, this all depends upon the actual toxin involved and its intensity, but for the worst-case scenarios, your ultimate fate will be set in stone.

What really sucks in this situation is knowingly being forced to breathe the toxins in. Because you can only hold your breath for so long.

But at the same time, each breath brings you closer to your premature demise.

In other words “damned if you do, damned if you don’t”.

So if the thought of this horrible scenario frightens you (it does for me), you should be highly motivated to invest in a high-quality gas mask.

There are reasons why the military, police departments, and firefighters all have them.

They prepare and practice rushing headlong into the worst disasters to assist their communities; even if it’s a chemical or nuclear attack.

They’re equipped to survive even if the air is deadly breath.

So if you’re like me, and you’re serious about preparing, then you must invest in a gas mask for survival.

How Gas Masks Work

CM-7M MILITARY GAS MASKA gas mask is simply a small, portable, personal air-purifying device.

It’s an invention with one exceptionally important task – providing detoxified “clean” air.

Similar in concept to a portable water filter that cleans water prior to drinking.

The key difference being you can avoid drinking water for longer than 3 minutes!

And they’ve been around a lot longer than you realize.

The ancient Greeks made the first known gas masks. They were crude versions using sponges.

A few centuries later, a pair of Iraqi brothers produced a rough prototype of a 19th-century version.

Ever since, soldiers have used them, miners, doctors, and civilians under wildly different circumstances, but always to achieve the same end goal: clean air.

But these were very primitive. They didn’t work well, at least not enough to ensure survival. But to be fair, chemical and nuclear warfare was still yet to be invented.

The first practical gas mask with real survival potential was created by a Brit named Edward Harrison in 1916, shortly after the invention of chemical warfare during WWI.

Since then, it has morphed into a symbol of the apocalyptic.

But as menacing as they may look, they save lives.

That is why you should add one to your survival gear in your home or in your bug-out bag.

But they do require research, preparation, and upkeep. And a little bit of know-how to buy the right one.

Gas Mask Half Vs Full

2 Types Of Gas Masks | Pros & Cons

The first steps to making a purchase are to determine which style of mask is right for you. And you do this by deciding what level of personal protection you desire.

Let’s start with the style first; you have 2 options:

1. Air Purifying Respirator

You could buy an air-purifying respirator if you want a down-n-dirty, quick-n-easy, cheap solution.

But take note, these respirators only cover your nose and your mouth.

While they technically purify the air, they expose your eyes.

And yes, eyeballs are extremely vulnerable to chemical damage and biological infection.

And to be blunt, you need your eyesight if you want any chance to survive a real chemical attack.

Stumbling around in the dark during an attack is a recipe for failure.

2. Full Face Mask Mask

The second option is a full-face mask. As you probably already guessed, this version includes eye protection. 

You normally think of these when someone utters the word “gas mask.”

They include a large filter attached below the mouth area and cover the entire face.

Your eyes are inside this mask, and you can see out of glass or plastic plates.

My advice? You really only have one option.

Go with the full-face gas mask.

Here’s a video showing you these different levels of respiratory protection:

↓ Levels Of Respirator Protection↓

Important Full-Face Gas Mask Options

The next most important decision to make is what type of respirator you want with your full-face gas mask.

Here we have 2 basic options to choose from:

1. Air Purifying Respirator

The first option is called an “air-purifying respirator.”

These are the most affordable and simple full-face options. The filter canisters on these units are replaceable and screwed directly into the mask.

It uses the power of your lungs to pull and push air through the filter.

This setup works fairly well as long as you get can get and keep a good seal.

You see, air pressure always takes the path of least resistance. As you pull air in and push air out with your lungs, YOU are creating this air pressure.

Now, if you have a good seal around the outside, then the path of least resistance is the filter itself. Which is what you want.

However, if the seal breaks or fails for any reason, the path of least resistance is no longer through the filter; it’s through the breach.

The breach route will have less resistance than the filtered route (hence the term “path of least resistance).

And that’s the one big disadvantage to this type of gas mask: any prolonged leak makes it 100% ineffective.

If there is a gap between your chin and the mask, outside air will bypass the filter and enter through the leak. And you may die.

So make sure that seal is airtight, and you’ll be fine.

Two notes of caution here:

1) If you have a beard, you’re going to have to shave it off because facial hair makes these masks difficult to seal.

Or, you can try what this guy in the video below did with his beard. He uses Vaseline to create a seal without saving off his beard.

↓ Beard Versus…Gask Mask!!! ↓

2) Be careful what tasks you perform while in the mask. You don’t want to run into anything that could break the air seal accidentally.

So try not to be clumsy or perform unnecessary acrobatics.

The bottom line is even if you initially establish a good seal, you still need to be diligent enough to KEEP a good seal.

2. SCBA Masks

The second variety of masks is by far the most effective and the heaviest. It is the type of mask that firefighters use to breathe in smoke-filled rooms.

It is called the “self-contained breathing apparatus system” (SCBA).

These masks require you to carry around a tank full of air (usually strapped to your back). But they provide the highest level of protection and security of any respirators on the market.

The tanks contain air and keep pumping it into the mask at a constant rate. This design keeps a positive pressure in the mask at all times, which essentially eliminates the need for a perfect seal.

Why? Because of physics. Air moves in one direction only. From high pressure to low pressure.

One simple way to understand this concept is by thinking about a flat tire. An inflated tire contains pressurized air.

Or another way to explain it; it has more pressure in the tire than the surrounding atmosphere.

Hence, when you get a flat tire, the air moves from its higher-pressure environment (in the tire) to the lower-pressure atmosphere (out of the tire), never the other way around.

So a gas mask filled with pressurized air will leak out, never in. As long as it maintains a relatively higher air pressure than the surrounding atmosphere, a leak is not dangerous.

Ok, enough science for one day…

But the SCBA setup is not without its trade-offs: for one, it’s bulky, heavy, and unwieldy in all circumstances. SCBA equipment is also a challenge to store in small spaces.

It takes up serious square footage in a regular-sized closet.

Also, most tanks only contain about 30-60 minutes of fresh oxygen anyway, and you can only refill them using special equipment.

So as you can see, there are upsides and downsides to each of your options.

It is totally up to you to determine what kind of chemical or biological threat you plan to face, how much you are willing to spend, and how protected you want to be.

Bottom line:

Not all gas mask setups are equal.

Some are glorified surgical masks, while others are only used by serious professionals in the most dangerous circumstances.

Now at this point, I could cop out and leave it at “just do your own research,” but that’s why you’re here, looking for advice. So here’s my advice.

Invest in a full-face air-purifying respirator, practice putting it on, and get a good seal.

And if you have a large and gnarly beard and refuse to part ways with it, good luck with that…

Here’s a short video covering the basics of using a full-faced gas mask.

Ok, before you pull the trigger on a purchase, we still have some more technical groundwork to cover. So stay with me…

How A Gas Mask Filters Work

The common full-face air-purifying respirator uses filter canisters to keep the air you breathe poison and disease-free.

There are three general types of filter designs:

  1. Particle Filtration
  2. Chemical absorption
  3. A chemical reaction to neutralize other chemicals

Particle Filtration

Particle filtration is the most common and the simplest of these three options (and it’s also the oldest). Like the ancient Greeks who held sponges up to their faces, particle filters block foreign substances from entering your lungs.

Recall a time when you’ve pulled your shirt over your nose in an attempt to block the smell of a particularly repulsive fart.

You were employing a crude version of particle filtration.

Very fine particulate filters are helpful against biological threats like anthrax. However, these filters have a limited life.

They can only hold so much particulate matter before they clog, so you have to replace them after every 20-24 hours of use (always verify these numbers on any gas mask filter you intend to purchase).

If you are trying to prepare for a chemical threat, then you will have to take a different approach.

While particle filtration is an effective system, it does little to purify the air of chemical agents.

For that, you will need to use an activated charcoal system for chemical absorption.

Most deadly chemical warfare agents come in the form of gaseous vapors (not particulates) and will slip straight through your particle filtration filter system and kill you.

Whether you are trying not to breathe household chemicals or a neurotoxin, your best bet is activated charcoal.

Activated Charcoal

Charcoal is a highly porous form of carbon. So porous, in fact, that it chemically attracts gaseous or liquid substances strongly enough to trap harmful organic vapors.

But it doesn’t catch everything.

Certain chemical agents aren’t chemically attracted to carbon and will pass straight through (such as sodium and nitrates).

This is to say that activated charcoal absorbs some chemical agents while ignoring others. Chemicals that could be as equally dangerous.

The final type of filter option uses chemical reactions to neutralize. This is a very effective way of defending against one specific chemical agent or another.

Still, you have to know exactly what you are up against so that the respirator is loaded with the right counteractive chemical.

For instance, in WWI, during chlorine attacks, soldiers would be fitted with masks containing sodium thiosulfate, which would react with and neutralize the chlorine in the air.

When you buy these filters, they are color-coded to indicate which type of gas or acid they work to diffuse.

Unfortunately, this type of mask is ineffective for most people because it’s impossible to predict what kind of chemical will be present in any attack.

No matter what type of filter you choose, you will have to invest regular time and money to maintain them.

No filter lasts forever; most only last about 20-24 hours of use.

CBRN GAS MASK FILTER NBC-77So every time you use your mask, you will probably have to replace the filter afterward.

Filters usually cost about $80 each, and it is highly advised that you keep several on hand for each mask you own at all times.

They also have a limited shelf life, so you will have to check up on them every so often and replace them once they expire (even if you did not get the chance to use them yet).

To avoid any immediate shelf-life concerns – these high-quality MIRA Filters have a 20-year shelf life!

↓ How Long Do Gas Mask Filters Last? ↓

A final note of caution:

Don’t use any filters that were made during WWII or early. Back then, asbestos was considered the ideal filter medium.

Now we all know that breathing asbestos is highly dangerous and will lead to asbestosis and lung cancer. You’ve been warned.

Final Thoughts

Here’s the rub: when it comes to any gas mask, a little late can be too late

Even the most expensive, advanced, top-of-the-line ones won’t save you if you can’t deploy them fast.

If you put your mask on after you realize there’s a life-threatening chemical in the air, you’re probably already dead.

Real life doesn’t happen like in the movies. Every second of respiratory exposure, be it biological or chemical, is a second closer to death.

It’s also impossible to tell when or where you’ll need it.

Sure, soldiers and police often get a heads-up. That way, they can deploy their masks quickly.

Civilians don’t get such notice.

We are at work, in our cars, or hanging out with friends most of the time.

And should word of a chemical/biological attack reach you while you’re away from home, you’re going to wish you’d taken it with you.

The best way to avoid this is to buy several and a set of filters for each one. Then store them in various places where you often spend time.

Keep one in your car, one at the office, one at the house, one in your get-home bag, and one in your bug-out bag.

If there is a place you spend a lot of time, stash a gas mask nearby.

You may also want to invest in some protective clothing, such as a hazmat suit.

Not only does this provide peace of mind, but it also increases your chances of surviving a nuclear or chemical attack tenfold.
