Picture of Red(neck) Ops Gas Mask
This a tutorial on how to make a Redneck Special Ops gas mask. It has changeable filters, and you can change the type filter for your operation.

Step 1: Materials

you will need 2 bottles, a knife, duct tape, hose/tubing, respirator, and rubber bands.

There are many sizes of bottles. You will want to pick a bottle with little grooves and little bumps, to minimize distortion. Perhaps a 1.5 liter or bigger, but not too big!

Step 4: Breathing Tube

Now for the breathing tube. This part is so that when you look down you don't suffocate. That is the only flaw of my design for using small bottles. hey, at least I'm honest.
First, you will need to get a decent sized tube, and drill a hole the same size as the tube in 2 caps.
Next, tape it until it is sealed around the sides.

Step 5: Filter

This is pretty simple.
First, take a bottle and cut off the top, and put a filter on the top.
Next, tape it down.
Make more if you will be using it often.

Step 6: Put It Together

Now tighten the caps on really tight, and even tape it.
And you want it hands free, add rubber bands.
I'm missing the part of where you put the filter and what it made from...

ok so it's a cool project.
B+ for effort D for safety and project follow through.
In fact i challenge you, you have the right idea, just redo it,
take your time, tape slowly use electrical tape it stretches and will seal better.
look up where Kleenex comes from I guarantee it will give you some ideas.
so yeah, step up, improve it. figure out a way to seal it to your face well.

I don't understand this, neither do I consider it to be a viable safe air system.

what do you not understand?

Well, I don't see how this is supposed to protect the user from anything. In the intro it says that it "can be used for anything from tear gas to west nile virus."

Tear gas effects the skin and eyes. This does not cover your eyes, therefore, it would not work. I would say that this might give you about one extra second of protection from inhaling tear gas.

As far as West Nile, there is a reason why biohazard workers wear full body suits.

Your design is not sealed, your filtration system appears to be a dust mask taped over the end of the bottle, there is no exhalation system, and it simply does not seem effective.

I am aware of the "Be Nice" Policy, but this is inherently ineffective, dangerous, and if anyone takes you seriously enough to treat this as a viable means of protection, they will come to harm. I rarely say things like this, but safety gear that is unsafe is one of my biggest pet peeves.

the gas mask is made up of a bottle that is LONG enough to cover your Whole face, now unless your face( eyes and mouth) is like a horse's face, it should cover your face, second, if you seal the mask up enough, it should be air tight when it is pushed/ pulled up against it, and when you use a surgical mask, like one made to protect you from the west Nile virus, you exhale through the mask, like my design, also if you don't have the thing super tight, the exhalation system is air escaping the mask, but when you aren't exhaling, it is stuck air tight against your face, so did i miss any thing?

To clear things up, maybe you should add a picture of yourself wearing the mask, to demonstrate how it fits.

sorry, my parents say no. trust me, i would, but i can't, i hope you under stand.
ilpug Bonar982 years ago
I think I understand your parent's point of view...

I'm with ilpug
very few circumstances would warrant the usage of this
over the usage of a real production breathing system.
there is a reason they spent millions building and testing
all sorts of breathing apparatuses.
first off, your using duct tape....
a single miss taped unwell sealed seam (look like you've got about 30)
where the tape doubles up on itself and creates a leak, would render this
USELESS!!! another problem, this mask doesn't seal to your face well enough.
production models have gaskets.

yeah me too.
