Now with an even lighter filter cartridge, the AutoFlow™ Gravity Filter is the latest evolution of backcountry hydration, combining filtration, storage and collection into a pump-free system.
- Featuring the latest hollow-fiber technology and the power of gravity, the AutoFlow filters more than 1.75 liters per minute without a single pump stoke
- Filter physically removes particles, protozoa, and bacteria down to 0.2 microns in size, including Giardia, salmonella, cryptosporidia and others
- 4-liter reservoir allows you to filter large quantities at once, making it perfect for groups
- Weighing in a mere 10.5 oz., the AutoFlow carries easily on lightweight backpacking trips
- Filter cartridge is fully field-maintainable and does not require tools for complete disassembly; can be cleaned repeatedly without disassembly for optimal flow recovery
- Filter directly into most any bottle or reservoir with included Universal Bottle Adapter
- Included shutoff clamp lets you control the water flow so you won't waste a drop of clean drinking water
