Delivery options:

Rocksolid guarantee

Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


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
