About This ADVANCED 2-STAGE FILTRATION: Engineered with a 0.1-micron Ultrafiltration (UF) Hollow Fiber Membrane and Advanced Activated Carbon, this filter removes 99.99% of Escherichia coli, protozoa, and heavy metals (mercury, lead), ensuring your water is clear and safe to drink without the use of chemicals, iodine, or batteries. SUPERIOR TASTE REDUCTION: Unlike standard filters that only trap sediment, our integrated Carbon stage actively reduces Chlorine, Fluoride, and agricultural runoff. This significantly improves the taste and odor of water from lakes, rivers, or questionable tap sources, making hydration enjoyable rather than merely functional. HIGH CAPACITY & LONGEVITY: One filter provides up to 1,000 Liters (265 Gallons) of clean water - equivalent to replacing 2,000 single-use plastic bottles. The filter features a "Backwash" capability to flush out trapped sediment, restore flow rate, and extend the unit's lifespan. CERTIFIED SAFETY & MATERIALS: Constructed from premium food-grade, FDA-compliant polyethylene materials. The filtration performance has been rigorously tested by SGS Laboratories to meet high safety standards, ensuring you have a reliable water source for international travel, outdoor adventures, and emergency preparedness kits. WHEN TO CHANGE THE FILTER: When you notice the flow of the filter is very weak or stopped completely, even after taking care of it with regular backflushes, you'll know it's time for a replacement. Visit our store to get your filter replacement. No need to purchase a whole filtration kit.
