LOL well thats not what I meant of course. The website has changed, it was a bit more sterile 6 months ago. Now it is looking a bit too glossy. I'm a bit hesitant to drop $30-$40 for one.

The more I think about it, the survival straw mentioned previously, with the "magical alloy", seems like it would be better.

There was a bit of info in the patent search I did about copper & bronze being used to purify water. Didnt' get into the details. Like I said before, someone's going to have to buy one, figure out who the manufacturer is, and basically disect it.

The "gubmint" did its filter research back in the late '90s and this particular gem wasn't included, so all bets are off re: effectiveness.

Apologies for dragging-up an old thread, but I've been interested in this product for a while. Very little info can be found, and while I'd be willing to buy one to test it out, I really don't have any equipment to do so.

I was able to find an abstract on the Science Technical Information Network of testing performed in 1984 by the Armed Forces Food Science Establishment

Evaluation of Survival Straws



Has anyone got any more info on this? It's surprising they've been around for so long without someone doing an evaluation?

i have an older one and it was very hard to draw thru.bending over with it to drink right out of the lake just about gives you a headache.i tried scooping out a cup of water and using the straw sitting down,still very hard to use.if i were to take one in a kit i would use it as part a gravity filter.

Eeewwww, Iodine. No thank you.

The PreMac Model SWP is virtually the same size as the straw type filters.

Yuk, again Iodine, you would be better off getting a Millbank bag, a titanium Mug, a Bic Lighter and a bag of Earl Grey or Lapsang souchong.

I like the survival, or filter, straw concept. Small, light, and cheap enough to have several on you, and keep one handy in a shirt pocket for instant use, they seem ideal. Unlike chemical treatments there is no need to wait, nothing to mix or measure, no delicate electronics or battery to fail.

I bought a few of the Frontier straws,a few yrs.ago,& Stupidly didn't pay attention to the instructions,I had read prior to using one.I got a Huge mouthful of charcoal,gritty funk upon my 1st sip from one of these,& then it tapered off gradually,thereafter.They worked well for me,After my Hazing of stupidity,lol!
