Here’s what you’ll need:

You will use a cotton woven fabric that should be prewashed, thread and elastic for this. If you have the string type of elastic that will be better.

• Cut 2 pcs 6″ X 8″ fabric in the fold
• 2 pcs of 2″ X 5.5″ strips of fabric
• Fold the fabric wrong side out. Stitch the sides.
• Fold  ¼” on both sides from the center then stitch over the folded sides.

Not let’s make the seam: place the 2 pcs of 2″ X 5.5″ strip of fabric underneath the mask, roll them so both ends come in front of the mask, up and down, and then stitch them to the mask. Roll the edges from left and right to come to the center of the mask and stitch them in order to create a casing.

Cut 2 pcs of 8″ elastic. Insert each piece of elastic on the casing using a small safety pin and stitch both ends of the elastic together. If you are using elastic thread you can just tie it up. You can pull the stitch ends of the elastic to hide them inside the casing.

Other Types of Masks

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 whatnot. 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 infrequent 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 affect 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 a 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 whatnot.

The idea of a DIY gas mask is nothing new. It started back in the ’40s 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 Mask

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

2. 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.

3. One of the most dangerous things that can happen to you in an SHTF situation when you get gassed/trapped in a fire is the 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 a 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.

4. 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 an 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.

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
