Voted the “Best Invention of 2005″ by Time Magazine, the LifeStraw is amazing! At around $20, you can have drinking water where ever there is a water source.
It measures 9″ long and 1” in diameter and will filter up to 264 gallons of water. It filters out 99.9999% of bacteria including E.coli.
Take it with you hiking, camping or store one away so it’s ready for an emergency.
There are no replacement filters to buy. When the flowrate drastically slows down, it’s time to change it out for a new one. Always best to have a spare on hand.
