The LifeStraw Peak Series Gravity Purifier Replacement Filter is built for those who refuse to compromise on water safety—whether you’re navigating remote wilderness, preparing for emergencies, or safeguarding your family’s daily hydration. This advanced ultrafilter membrane removes viruses (including Rotavirus and Hepatitis A), bacteria (such as E.coli and Salmonella), parasites (like Giardia and Cryptosporidium), as well as microplastics, sand, dirt, and cloudiness. With a gravity-powered high flow rate of 30 liters per hour, it delivers clean water quickly—no pumping or electricity needed.
Engineered for durability, each filter delivers up to 18,000 liters of safe water (enough for about five years for a family of five) and comes with a 1.2m hose and adapter for direct bottle filling. Every purchase supports LifeStraw’s Give Back program, providing a year of safe water for a child in need. LifeStraw stands out for its science-backed approach: products are validated to World Health Organization, US EPA, NSF International, and Water Quality Association standards, and the company is both a certified B Corp and Climate Neutral Certified—reflecting a deep commitment to people and planet.
