Katadyn Gravity BeFree 3.0L Water Filter — Fast Flow, 0.1 Micron EZ-Clean Membrane

Effortless hydration for serious adventures

The Katadyn Gravity BeFree 3.0L Water Filtration System combines a compact, collapsible soft bottle with a high-performance 0.1 micron filter. Designed for solo travelers and small groups, it makes clean water accessible wherever your path leads. Fill, hang, and let gravity do the rest while you focus on the moment – from sunrise breakfasts to trail-side breaks.

How it works

A durable 0.1 micron hollow fiber filter targets fine particles and microorganisms, delivering water that’s ready to drink on the move. The EZ-Clean Membrane makes maintenance simple: shake or swish to remove debris, with no backflushing or tools required. If needed, you can swish the membrane directly in a lake, river, or stream and keep moving.

The system is designed to be practical in real-world conditions. Water quality varies, but the BeFree model can handle cloudy water and still provide a steady flow without chemicals.
