Manufacturer's Description

Introducing the world's first osmotic desalination kit. Intended for emergency use, the SeaPack produces a potentially life-saving drink directly from seawater. 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 97% of the salt.

Because the SeaPack is passive, there is no pumping involved. This is obviously an advantage if the user has been injured and would have difficulty operating a pump-style system.

Produces 0.5 liters of drink in 5 hours at 68°F (20°C), in 3.5 hours at 95°F (35°C), and in 8 hours at 40°F (5°C) from seawater

High salt rejection – 97%, about 0.5 gram of salt is added to the 0.5-liter drink

The eight 4.5-fl-oz (135ml) syrup charges included with the SeaPack will make 4 liters of drink from seawater or up to 24 liters (typically 16 liters) of a sports drink from freshwater.

Retailers' Descriptions

Here's what other sites are saying:

In a survival situation, your ability to hydrate yourself is second to none, so be prepared to turn any available water supply into a survival drink with the SeaPack Emergency Desalinator from from Hero Water. Simply fill the bag with salt water or other questionable water sources and mix in a 4-ounce bottle of "Nutrient Syrup Charge - a forward osmosis membrane filter that attracts the pure water molecules to the electrolytes in the syrup which then pass through the pores of the membrane for filtered, desalinated water that doesn't require pumping.
