This is one of the neatest products I have seen in awhile for water purification, mainly because of its ability for re-use and being very lightweight.
Now with many methods of water purification on the go, or in a bug out situation, they are either heavy, bulky, require batteries or make your water taste funny.
I have different methods of purifying water in my bug out bag, redundancy is the key. It all comes down to time and weight, how much time do you have and how much weight can you carry. Carbon filterer items work well, however they are bulky and take up weight, small iodine tabs work great and last a long time, however they will leave a unpleasant taste in your water, not a game changer, but it is still not pleasant.
The Solar Bag offers you the ability to not have to deal with weight, bulk OR taste.
The beauty of this is that empty it weighs less than a pound, thin and will fit easily in any pack and plus its reusable hundreds of times, and only requires sunlight to work!
-Tested by the University of Arizona, proven to filter out Viruses, Bacteria and Protozoa
-Up to 9 Liters of Water a day
-Can be Re-Used Hundreds of Times
-Will Work even with cloudy Skies
How it works is very simple.
1) Take water from a freshwater course, pour into the Solar Bag through the attached cloth filter
2) Lay Solar Bag flat in the Sun
3) Wait 2-3 Hours on a Sunny Day, 4-6 hours on a Cloudy Day (or if water is tea-colored)
4) Re-use as needed
The magic happens in the bag itself, inside is a nano polymer mesh inside the Solar Bag, under sunlight it activates the photochemical processes that destroys the contaminants in the water.
The Solar Bag may seem a little pricey coming in around $76 on Amazon, however you will not be using this on a daily basis, it is something that you will just set in your Bug Out Bag and leave it for a rainy day. If you ever need it you wont have to worry about it having gone bad, as long as its daytime you can get water.
