DIY Gas Mask To Survive Contamination

We are all living in an unpredictable and sometimes dangerous world, where bad things happen to good people all the time.

One of the “iconic” must-have items according to those in the know for a prepper’s stockpile is the gas mask.

What exactly is a gas mask, though?

Well, to put it simply, a gas mask is that thing that has the potential to save your life by filtering toxins from the air when SHTF in one of the following situations:

  • In a natural/man-made disaster, when airborne pollutants fill the air. In the aftermath of volcanic eruption for example, the dust and ash in the air can kill you by obliterating your respiratory system. The same principle applies in an office building fire.
  • In a riot eliciting a chemical attack, a gas mask will make the difference if you have one when confronted with CS gas, tear gas or whatever.

You get the picture: basically, a gas mask will help you keep your lungs clear and your nose, mouth, eyes and mucous membranes protected from harmful substances. Having a gas mask ready or knowing how to improvise an effective DIY one on the fly is crucial both for your long term survival and your physical comfort in an emergency SHTF situation.

There are lots of disaster scenarios where a gas mask will help you mitigate the contamination in the air regardless of whether it’s smoke, particulates, infectious agents, airborne diseases, chemicals or what not. Fortunately, in this day and time, decent gas masks and respirators are commercially available everywhere, both online and offline.

You can buy a military-grade gas mask from the internet, in hardware stores, in Army surplus outlets etc, but there’s a flip side to that coin too: the coin itself, meaning that they are pretty expensive to buy and to maintain.

While they perform excellently, standard gas masks/respirators require regular maintenance, as in frequent changing of the filter cartridges, proper storage and so on and so forth. All these come with a hefty price tag, especially when times are tight.

Also, and, most importantly, you can’t carry a gas mask around with you 24/7/365. That would be pretty weird and uncomfortable, because gas masks are bulky and heavy. It would be very peculiar to carry around a gas mask with you at work, don’t you think? People will label you as a terrorist or a nutcase.

Also, keep in mind that standard gas masks don’t function well if you have facial hair; any type/length of facial hair will negatively effect the crucial tight seal a gas mask has against your face.

However, you should know that there are alternatives to buying a regular gas mask. Yes, you can build yourself one using readily available materials (stuff you already have in your house) which are also dirt cheap even if you don’t already have them.

There’s a downside to a DIY respirator though: you can’t trust it with your life, especially in cases of biological or chemical attack, because it’s not anywhere near as effective as the real thing so using one in a life threatening situation is a desperate measure, the last resort..

Fair warning: A DIY gas mask / respirator is primitive when compared to a standard/military grade one and offers very limited protection especially in a chemical/biological attack; you should be aware of the fact that tear gas (for example) is no joke; it can seriously injure your respiratory system and lead to death in certain situations especially if you suffer from chronic lung disease or asthma. To put it bluntly, a homemade gas mask should be Plan B because it can never compete (efficiency wise) with a military grade mask that features special filters, fibers, vents and valves and what not.

The idea of a DIY gas mask is nothing new. It started back in the 40’s during WW2. The citizenry was instructed on the how to’s regarding DIY gas masks and the concept continued with Occupy Wall street protesters along with  many others Arab spring: Syrian, Egyptian, Maidan in Ukraine, Occupy in Hong Kong etc.) as people were trying to protect themselves against the chemical weapons used by the regime police and military forces.

How to DIY Your Own Gas Mask

Now, let’s take a look at the most popular DIY methods for gas masks, shall we?

1. The most basic DIY gas mask that can save your respiratory system (and implicitly your life) in the case of an event such as a volcanic eruption or a fire where ash and smoke fill the air. If these don’t sound probable to you, think about Pompeii and Mount St. Helens and 9/11.

In these cases, a fairly effective gas mask can be improvised under exigent circumstances from a simple cotton T-Shirt. Yes, it’s that “your T-Shirt can save your life” kind of a deal, when your ripped T-shirt will work as an efficient anti-dust/ash mask.

All you have to do is tear the T-shirt apart and use strips of fabric to cover your nostrils and your mouth (tied at the back of your neck) and voila, this is the simplest DIY gas mask project. For best results, you should get the cloth damp before using it, if possible.

2. One of the most dangerous things that can happen to you in a SHTF situation when you get gassed/trapped in a fire is loss of vision. Swim goggles will save your life if you’re caught in a stampeding mob “sprayed” with tear gas and running for their lives, soaked in panic. To stay alive in such situation, you’ll be required to see properly if you want to make it to safety. A quality pair of swim goggles is a must-have item to keep around in your “tactical” bag.

Cider vinegar can be used to protect you from the inhalation of tear gas, remember that folks. You can use a bandana soaked in cider vinegar put around your nose and mouth until you get to safety.

3. The soda bottle gas mask is my favorite DIY project because it offers a reasonable amount of protection from various contaminants, it’s very simple to manufacture and it doesn’t require huge skills or exotic materials to build it. It’s also pretty effective for a home-made gas mask and it can be built in 15 minutes tops, if you have the necessary materials and a little bit of (prior) training.

For your soda bottle gas mask project you’ll require a sharp cutting tool (razor blade, exacto knife, sharp scissors), a permanent marker, glue, a 2 liter soda bottle, rubberized foam insulation strip (at least 1” wide) and a N95 particulate mask. Total cost: maybe $5.

You’ll have to clean the 2 liter plastic bottle and remove the labels. After that, draw a U-shaped area using the marker, big enough to fit your face and yet not too big. You should start with a smaller cut and work your way up from there because you can always trim more but you can’t put it back. You’ll need a fit snug against your face for an efficient seal.

The bottom of the bottle must be cut away, along with the U-shaped section (using the template lines drawn with the marker to fit your face).

You’ll end up with a basic shape that can be further adjusted for an optimal fit until you get it right. Keep in mind that the mask should fit your face tight yet not be uncomfortable.

Next, you’ll use the rubberized foam insulation as a seal for the edges of the bottle until you end up with a secure, complete seal and you’ll also make a circle of foam insulation inside the bottle that will serve as a resting place for the filtering element (the N95 mask) 2 inches up from the spout.

The elastic bands from the N95 mask will be removed for later use, along with the metal bridge. The N95 mask’s edging must be carefully cut. Just leave enough to keep the edges sealed. After that, the N95 mask must be placed inside the neck of the bottle, with the filter pointing out and down towards the spout. The elastic bands from the N95 mask will be used to secure the gas mask firmly on your face (as in the video below).

That’s about it, just remember to keep the soda bottle gas mask stored in a well sealed plastic bag, removing as much air as possible from it, thus preventing the N95 mask (the filtering element) from getting contaminated.

Remember that all these DIY gas masks are to be used only in emergency situations when you don’t have alternatives. If you have other ideas or patterns, please share them with us in the comments section below.

    • Doesn’t let us know how to make it… -_-

  • A gas mask must never be used indoors (office) where there is a lack of oxygen. It does filter smoke from a fire, but if the fire is indoors, it also burns up oxygen. Outdoors whee there is likely plenty of oxygen, it should work just fine.

  • re: pop bottle gas mask. How do you attach the bands from the N95 filter to the soda bottle?

  • I don’t recall hearing the instruction on how to attach the two rubber bands removed from the N95 mask, and there were no shots close enough or sufficiently still for me to determine the method of attachment.

  • Thanks for the input on DIY Gas Mask. Could you go one step further and tell us which gas masks would be good to have. And what to look for when purchasing the filters for them. Thanks again.

  • Hey there folks.

    To answer your questions:

    You can attach the rubber bands to the soda bottle by perforating the bottle wall (in the respective area) with a sharp object –>I’d use a thin hot nail ,thus creating a small hole. The rubber band goes through that hole; you’ll have to make a knot at the end of the rubber band, so it doesn’t slip through the hole.

    Also, if you’re a perfectionist, you can use some sort of glue to make the hole in the plastic as sealed as humanly possible 🙂

    Generally speaking, the best gas masks are mil-spec/military grade, I’d go for a gas mask that is compatible with the NATO standard ( 40mm NATO threaded filter canisters), these are easier to find/popular and a tad cheaper.

    Here’s a pretty damn’ good choice if you have the green: it’s the one used by Israeli military

  • Hi Chris,

    I live near a surplus Army/Navy store. They sell gas masks there but I suspect they are pretty old and vintage. Would something like this work? They seem to work but I wouldn’t want to bet my life on one without more knowledge.


    • Yes they will work perfectly just buy a new filter to fit the mask and check for any cracks, rips, and tears in the mask if there are any just deal it with some silicon glue and you’ll be set. You can also make a filter using activated carbon gauze and a soda can

  • i would name it “2 liters of hope”mask.
    im going to make a few of these,,and try them ot,,ill let you know how they work for me..

  • in addition to using the n-95 mask, you can take a soda can and cut the center of the top and bottom out cut the can in half place a coffee filter in the can fill it with activated charcoal place filter on top press two halves together to form a canister and place in the bottom of 2L bottle sealed to force air to enter thru filters and charcoal or carbon

  • Can we not just use a pesticide/paint mask for about $25 off amazon? sounds like it still have a fairly good filter – activated carbon etc…
    Thank you

  • You have an advert for survival MD on your page.

    The guy is a wanker who claims his dad died because of katrina but has a secret on how to help others not go through that but charges money for the info.

    He’s either a liar or douchebag and it is beneath you to have his advert on your site.

  • Dr. Mercola found out that the common cold/flu brew inside of your ear 2-3 days before showing symptoms. When you do think something is not right – pour hydrogen peroxide in each ear and let it sizzle from 5-20 minutes – depending on how much is going on in that ear.
    Now with a question about a gas mask ….. humm …. shouldn’t the ears be protected too?

  • Wouldnt trust a homemade gas mask with anything even with cs/tear gas, just get some cheap mask offline that will accept 40mm filters. Anyone making homemade protective gear like this is asking for trouble.

  • I think it would be much easier to just make a video for the gas mask and every body would prob. find it much easier to figure out what’s what without looking it up.. thanks

  • I was able to find good info from your blog articles.

  • It’s going to be ending of mine day, but before end I am reading this
    wonderful piece of writing to increase my knowledge.
