LIFESTRAW LifeStraw Peak Gravity Water Purifier System

The LifeStraw Peak Gravity Water Purifier System is a rugged, high-capacity portable water purification solution designed for emergency preparedness, camping, and travel. This advanced system delivers up to 8 liters of filtration capacity and boasts an ultrafilter membrane that removes 99.99% of viruses, 99.999999% of bacteria, and 99.999% of parasites—including E. coli, Salmonella, Rotavirus, Hepatitis A, Giardia, and Cryptosporidium. The 0.02-micron membrane also eliminates microplastics, sand, dirt, and cloudiness from your water, ensuring it is safe and clean to drink.

With a rapid gravity-driven flow rate of 30 liters per hour, the LifeStraw Peak Gravity System requires no batteries, pumping, or external energy source. Simply fill the reservoir with untreated water, hang the bag, and let gravity do the work. The system comes complete with an 8-liter gravity bag, a 1.2-meter hose, ultrafilter membrane, adapter for direct bottle filling, prefilter basket, leakproof cap, and a custom backwash syringe for easy maintenance.

This purifier meets rigorous US EPA and NSF P231 standards for virus, bacteria, and parasite removal. Its premium, BPA-free materials and robust design are ideal for basecamp, survival situations, or RV and van life. The membrane lasts for up to 18,000 liters—about five years of safe drinking water for a family of five—making it a cost-effective, reliable choice for groups or solo adventurers seeking peace of mind in the wild.
