Water filter that looks like a blue gas can. The blue is so you know it is water instead of gas.
Take up to 5 gallons of contaminated water from a source and carry this with you. The water is made potable by pumping the water out of the can. This is state of the art technology based on the Lifesaver bottle. Removes bacteria, protozoa, and viruses.
Process up to 20,000 liters. A great option for emergency water as opposed to storing water. Or if you are going into the jungle, strap this to the side of your motorcycle. Will not remove salts.
Too big for the average traveler, You might want the bottle instead.
