Question:
I am departing offshore next April and I would like to include in my grabbag a hand operated reverse osmosis water filter like the military use. Ihave searched the net and can find heaps of places that sell electric or gaspowered ones, I can find articles about how good the hand operated ones arebut I can't find anyone who sells them.

Answer: I thought all the cataloges sold PUR 06's.

btw, Katydyn makes filters, not reverse osmosis filters. Filter take some or alot of junk (depends on the filter) from the water, reverse osmosis units takethe salt and other disolved minerals out.

You presumably mean water maker, not water purifier?If so, the device you want is the PUR, as another has said, but the companyhas renamed itself, and is called Katadyne or something like that. Theirsmallest model can be motor or hand powered.
