The LifeStraw Peak Series Gravity Purifier Replacement Filter delivers uncompromising water safety for outdoor adventurers, emergency preppers, and families alike. Using advanced ultrafiltration, it removes viruses (including Rotavirus and Hepatitis A), bacteria (like E.coli, Salmonella), parasites (Giardia, Cryptosporidium), microplastics, sand, and dirt—ensuring clean water wherever you are. With a gravity-powered flow rate of 30L/hour and a long-lasting 18,000-liter capacity (about five years for a family of five), this filter is engineered for reliability and ease of use. Each purchase supports LifeStraw’s Give Back program, providing a year of safe water to a child in need. LifeStraw stands apart for its science-backed, independently lab-tested products, validated to the highest global standards (WHO, US EPA, NSF, WQA), and is proud to be both a certified B Corp and Climate Neutral Certified.
LifeStraw products have a history of use in some of the harshest conditions around the world, from refugee camps to natural disasters to extreme back-country, our products have to work because lives depend on them. Our testing and transparency is unparalleled and we use the most trusted performance criteria based on protocols established by the World Health Organization, the US EPA, NSF International and the Water Quality Association.

"Used this on several trips now and my interaction with customer service was stellar! I’m a life long user and am planning to buy more in the peak series. Looking forward to seeing if any small filters will also do virus removal! Thank you for being such a great company."
"I love this purifier! I would like to see an optional activated carbon filter available to be added on."
