Considerations & Trade-offs
- Gravity filtration is convenient, but it still depends on having a place to hang or support the reservoir while water runs through the system.
- The 1-gallon bladder offers useful capacity, though it adds bulk compared with smaller, more minimalist filter setups.
- The included MINI filter is dual-threaded for versatility, but some use cases may still require the included hoses, hardware, or cleaning accessories to get the full benefit.
- Backwashing and sanitizing after outings are recommended, so this is a reusable system that asks for a bit of routine maintenance.
