Introducing the world's first and only osmotic seawater desalination kit. Intended for emergency use, the SeaPack produces a life-saving drink directly from seawater. Perfect for use on your off- shore boat, sea kayak or for use in your life raft. The filtered drink is very similar to the juice from pressed grapes and provides 480 calories from each half liter -- an important energy source during emergencies. The tight osmotic membrane rejects a full 97% of the salt. Imagine that you've had to abandon ship and don't know how long you'll have to float around in a life raft waiting to be rescued. It's hot and there's not much fresh water available. How are you going to survive in your life raft? Now imagine being able to convert sea water into a life giving drink without having to wear yourself out pumping a mechanical reverse osmosis seawater filter for hours in the scorching sun. The SeaPack passive emergency desalination system does just that. Without having to hand pump or use electrical power the SeaPack removes pure water from the sea and transforms it into a drink that is high in calories to provide you energy. Perfect for surviving in a saltwater environment. benefits... Produces 0.5 liters of drink in 5 hours at 68 F No pumping or electricity required High salt rejection – 97% specifications...
