The general term for the type of unit you are talking about is reverse osmosis. Also refered to as desalinators, one company making them is PUR (line over the U so it is pronounced as PURE), looking in my "Boat US" catalog I find; A) Manual Survivor-06 produces 1 quart per hour, 2.5x5x8" shipping weight 4 lbs. ~$500 US B) Manual Survivor-35 produces 1.2 gallon per hour, 3.5x5.5x22" shipping weight 10 lbs. ~$1400 US They also make units that run on 12VDC power and save you the pumping if you have electrical power. The water quality is excellent, as good as the best bottle water you can buy in a store. There are spare parts and maintainence considerations if you plan to use them on a repeated basis. Either you have to use them frequently or treat them properly before storage. Not a problem for a unit packed in an emergency kit. michael pjunold_at_daimi.au.dk wrote: > > Hello all > > Does anyone have any experience with water-filters for normal > sea water? > Some months ago I saw a TV program, about some capsized sailor > in the south-sea, who had this small water-generator/cleaner > device.
