When access to clean and safe drinking water is not going to be a reliable option when traveling, camping, hiking, hunting, or just surviving, then bring along one of these cool new LifeStraws. These innovative personal water filters are shaped and used like a regular straw to suck up and effectively filter up to 1000 L of dirty, contaminated water. It's designed to remove a minimum of 99.9999% of waterborne bacteria, a minimum of 99.9% of waterborne protozoan parasites, and reduce water turbidity by filtering particles of approximately 0.2 microns. It contains no chemicals, no batteries, no BPA, and no moving parts to wear out and has a 5 year shelf life. A great lightweight and relatively inexpensive solution to have around when you just can't trust the water. Check out the video demo below to see it in action.
