Claim was that 98.4% of the "salt" content was removed. It's pretty pricey at $500, and its yield of 2 pints per hour sounds about equal to the perspiration that would be needed generate the 800lb/sq inch force needed to force intake water through the membrane. Anyone have experience with such a unit? >> Rich, I don't have any experience with water makers, but I did do some research on them for a trip I am planning. My conclusion was that the water maker you mentioned was too slow to use for anything but survival purposes, which is how it is marketed. Paddlewise's Cajun Gulf of Mexico crosser, Arthur Hebert <A HREF="http://homepages.gs.net/seacajun">Arthur Hebert's Sea Kayak Page</A> , sent me an email in the past saying that the higher capacity manual water maker he used on the crossing felt too slow and that if he had to do it again, he would get an even higher capacity model. Do a search for the Pur website, and you can see these higher capacity models, which I think ran in the $1000-2000 or even more range.
