Great for hiking, camping, or any outdoor adventure, the LifeStraw Steel Personal Water Filter helps you turn any water source into drinking water. A 2-stage filtration process cleans water to keep you hydrated: a replaceable, activated carbon capsule reduces bad taste, organic chemical matter, and chlorine, and advanced hollow fiber membrane technology filters to 0.2 microns, removing over 99% of waterborne bacteria and protozoa. The sturdy, stable 9” design is constructed from food-grade stainless steel, so it meets US Food and Drug Administration regulations and standards. To keep from any unpleasant aftertaste, the filter uses no iodine or iodinated resin chemicals. BPA free and meets US EPA drinking water standards. Weight: 5.6 oz.
