While an Israeli Gas Mask and Filter usually runs less than $50.00 from any number of sources on the web, and a better bet than this, I thought this DIY "Gas Mask" was still pretty interesting.

The author got the idea from a several articles produced in 1942, one from Time Magazine, and another from Popular Science with illustrations and instructions from that article. The Instructables tutorial is worth reading to see the reproduction of the Popular Science article alone in my opinion.

The gas mask the author produced doesn't have eye protection, a drawback, but still...

Enjoy!

Interesting post.

I would change the procedure used to make charcoal. The process described in this post results in burnt wood, not charcoal.

Charcoal is made in an "almost anaerobic" process similar to procedure used for making char cloth.

Depending on the gas encountered, I would call that a MAJOR drawback, possibly fatal...

I can't think of a gas it wouldn't be a draw back for.

True, but if you have the respiration piece in place, you could put a plastic bag over your head and achieve as much coverage as most gas masks would. Do you think this would filter out particulates like bacteria or viruses, or just get the chemicals that adsorb to charcoal?

A truly Darwinian mask. Since the original inventor died via contamination to the eyes, the mask couldn't evolve. wink

For the shown use (urethane) Big Box home improvement stores have serviceable masks at almost no cost compared to the potential lung damage risk of a DIY mask not working. JMO

looks totally useless to me. For DIY projects, buy one from the hardware store.

for chemical warfare, it's won't help a bit. There are a few things you just shouldn't improvise. Just buy a proper one.

Hmm, $50 sounds like a helluva good deal for an Israeli gas mask because it's a quality, well proven product. However, I don't see any real use for that DIY mask other than maybe educational value.

Also, when you look at the time and stuff needed to build that DIY gizmo, it's not even that much cheaper compared to $50 for a military or industrial gas mask (depending on your needs).

A good mask is worth it's money. But 50 dollars isn't going to buy you a good mask. Surplus masks are generally outdated/expired. Also the filter generally canisters are expired or are trainings cannisters. All of them makes them less or non protective at all. Expired reactive canisters can even be harmfull for the user.

"...Surplus masks are generally outdated/expired..."

Plus it is hard to get the proper sized mask when you buy on-line, which is probably how most folks obtain such a mask. Bad fit equals worthless mask, no matter how fresh the filters. My agency used to pass out those compact USGI M-28 "Grasshopper" masks for riot duty. No fitting, just passed them, in their cute little green pouches, out like candy. If you ever actually put the thing on, chances are that it wouldn't fit (plus the filters were probably way out of date)...
