Katadyn BeFree Gravity Bag

Large‑Capacity Gravity System: This model holds 6 litres of water, allowing group hydration and base station use rather than single‑user only.

Fast Flow & High‑Efficiency Filter: Features the EZ‑Clean™ hollow‑fibre membrane (0.1 µm pore size) with a flow rate of up to 2 litres per minute, making it effective for quick water provision in the field.

Foldable Bag & Hangable Design: The reservoir bag is collapsible and includes a carrying/hanging strap, so you can fill it, hang it (e.g., tree, vehicle, structure) and let gravity do the work—no pump required.

Rugged & Lightweight for Field Use: With a weight of approx. 263 g for the 6 L version, the system is lightweight and suitable for tactical, expedition or emergency readiness use.

Filter Maintenance Simplified: The filter membrane can be cleaned in the field by shaking or swishing the bag in water (no complex back‑flushing), enhancing practicality in austere environments.

High Lifetime & Reliable Output: The unit is rated to treat up to ~1,000 litres (depending on water quality) before filter replacement is recommended — making it cost‑effective for repeated field use.
