The LifeStraw Go is an advanced water bottle featuring a primary filter that protects against bacteria, parasites, microplastics, and chemicals. The second stage with the activated carbon filter reduces chlorine and improves taste. The leak-proof, BPA-free bottle is perfect for hiking, camping, international travel, and emergencies. Simply fill it with water from a lake, river, or tap and filter it on the go. This means no more need for single-use plastic bottles. LifeStraw filters are rigorously tested to meet the protocols established by the US Environmental Protection Agency (EPA) and NSF International/ANSI. The easy-to-clean bottle and cap are dishwasher safe; just remove the two filters. Available in two sizes, 650 ml or 1 liter, and in various colors. Your purchase makes a difference: LifeStraw's Doing Good program provides a needy child with clean water for a year. Additionally, LifeStraw is proud to be a B Corp and climate-neutral certified brand committed to meeting the highest standards for verified social and environmental performance, transparency, and accountability.
