Hydration Technologies X-Pack: According to the manufacturer, "provides up to 32 liters of clean drinking water from a surface water source over a ten day period. Use nearly any water source to generate clear drink. Purity levels are comparable to reverse osmosis systems, and the filter meets or surpasses reductions for bacteria, viruses and cysts as specified by the EPA for water purifiers".
Hydration Technologies SeaPack: According to the manufacturer, "the SeaPack produces a potentially life-saving drink directly from seawater in a reusable bladder. The filtered drink is very similar to the juice from pressed grapes and provides important calories that will be a source of energy boosting nutrients during an emergency survival situation. The tight osmotic membrane rejects 97% of the salt".
