Utilizes any body of water (puddles, swimming pool e.t.c).
Requires simple maintenance
Does not leave a chemical taste in the water like other water treatment methods.

Drop the pack in any source of dirty available water.
The pack works by forward osmosis(same process of plants extracting water from soil).
Water is separated from contaminants by a thin membrane within the pack.
A sports drink syrup on the clean side of the membrane acts as a draw solution.
Water diffuses across the membrane to dilute out the syrup.
The pack is fortified with salt and sugar to aid absorption of the water into the body, and flavoring for better taste.
