I think those new rations use the water filtering technology that is referenced in the original post.

It's an interesting piece of equipment to consider for survival conditions if it works the way it's advertised. They have several different sizes, but, the one I referenced above is a 2 liter flexible container. You place it in any source of water, and it filters bacteria, viruses, cysts, etc.

There are other versions,like the one originally mentioned, which is re-usable 3 times per day for 10 days, which sounds very interesting.
The company lists several branches of the US Military as customers.

Getting back to the original question about the water purifier, has anyone actually used or have experience with these units?

As I said on previous post on this product; "[censored] on it"!

I don't know the medical aspects of this method of urine use, but my concern is possible illiness that may cost you more liquid loss from your body than you would save by hydrating the MRE with urine or contaminated water.

No experience, it just seems logical.

While drinking filtered urine sounds icky, most urine is sterile, unless you have an infection of some kind. But still, it's way down the list on my water sources..... <img src="/images/graemlins/crazy.gif" alt="" />

All's I can say is that my C.O. (commanding officer, for those militarily disinclined) wanted me to buy these for our brigade (4000+ ffolkes)...I heartily reccomended against them. Cost was a factor (dollars per liter...and it's ****** gatorade, not water), but I felt our ROWPU's (motorized filters) did a darned sight better. And cheaper.

Do such "gadgets" have their place? Yes. Can you filter urine? Yep.

Don't count on your kidneys keeping up with the urea, tho. The filters won't handle that...in simple terms, in an extended situation, your kidneys would shut down and kill you <img src="/images/graemlins/smile.gif" alt="" />

Still, a cheap, positive-pressure membrane that filters giardia/viruses would be handy. Just add water, and blow.

You do however realize if you are wrong about the sterility, URINE a lot of trouble. <img src="/images/graemlins/shocked.gif" alt="" /> <img src="/images/graemlins/grin.gif" alt="" /> <img src="/images/graemlins/shocked.gif" alt="" />

I thought urine had a lot of salt in it. Even if it's sterile, drinking it (filtered or not) would be like drinking seawater, a well-known survival no-no. Only distillation or reverse osmosis can get the salt out.

She is correct. Urine is quite sterile. More so even than blood.

Bounty !
do you really think of all those puns all by yourself, or is "Bountyhunter" a collective name for several merry individuals ?

For some strange reason I had the urge to clarify....

I do talk to myself a lot when I want an intelligent listener that will answer. Depending on the subject of the conversation, I may use different tones, talking styles and speeds. Depending on your point of view, I am either multi-faceted, multiple personality possessed, diverse, multi-dimentional, or just plain out of my mind. Although I have gained enough weight recently to actually carve several full size adults from this body, there is only me, the one and only, which so many of my friends agree is sometimes one too many. <img src="/images/graemlins/crazy.gif" alt="" /> <img src="/images/graemlins/grin.gif" alt="" /> <img src="/images/graemlins/tongue.gif" alt="" /> <img src="/images/graemlins/shocked.gif" alt="" /> <img src="/images/graemlins/smirk.gif" alt="" />
