MSR HyperFlow Replacemnt Cartridge S19
| Availability: | In stock (6) |
A small, lightweight replacement cartridge for the HyperFlow Microfilter. Because the filter uses Hollow Fibre Technology, where fibres are somewhat more brittle than traditional filter materials, we recommend packing a spare cartridge on longer trips – here it is.
- Note: this is not compatible with the AutoFlow Gravity filter.
- Do not allow the cartridge to freeze after initial use.
