Learn about HTI's one-time use emergency desalination filter pouch, the SeaPack Crew™. It removes 97% of salt from sea water while producing one half liter of a clean flavored survival drink that provides both hydration and energy. The SeaPack Crew relies on forward osmosis to pull water across a very tight membrane filter, the same way plants draw water into their roots. The purity and salt rejection is comparable to expensive reverse osmosis equipment. Don't get caught in a disaster or survival situation at sea without an adequate supply of HTI's SeaPack Crew desalinators. Visit our website to learn more www.HTIwater.com
