Falling ill is always a bummer no matter which part of the world you're at. Sometimes when we head out backpacking or travel on our honeymoon, we tend to take drinking water for granted - and that could come back and haunt us should we fall sick while consuming local tap water or ice cubes. The iStraw prevents such a scenario as it comes with a special membrane, featuring micro-filtration technology that cleans your water, resulting in protection against water borne bacteria and protozoa that are present in the drinking water and ice of many countries. It claims to reduce up to 99.99999% of all waterborne bacteria, including Giardia and Cryptosporidium. Each iStraw can filter up to 500 litres of water when used properly. Take no chance today and pick up the iStraw for $39.99. If only it came with a volume counter - then you'd know when to change the iStraw.
