Portable purification in an ultra-small package - 0.01 micron pore fiber filaments make this filter effective against 99.99% of bacteria and parasites without the use of iodine or any other chemicals! It can filter up to 1000 liters and docks with beverage bottles, plus it's equipped with an attached rope for a hands-free carry - all weighing less than 3 ounces (75g). Incredible!
