A lightweight replacement cartridge for the AutoFlow Gravity Filter. Because the filter uses hollow fibres, it is slightly more brittle than ceramic filters, we recommend packing a spare cartridge on longer trips – here it is.
- Compatible with AutoFlow Gravity Filter, not compatible with the HyperFlow Microfilter
- Nominal 1500L filter life is for clear water, turbidity will reduce its useful life to 1000 to 1200L
- Do not allow the cartridge to freeze after initial use
