Pros & Cons
What We Like
- 50,000-liter ceramic filter life is the longest of any portable pump filter
- Silver-impregnated 0.2 micron ceramic element inhibits bacterial growth
- Swiss-made with a 20-year manufacturer warranty — built to last a lifetime
- Ceramic element is field-cleanable to restore flow rate indefinitely
- Proven expedition-grade reliability trusted by military and humanitarian organizations
Watch Out For
- $370 price point is the most expensive portable filter on the market
- 20 oz is heavy for ultralight backpacking
- 80 pump strokes per liter requires significant physical effort
- Does not remove viruses — ceramic pore size is 0.2 micron, not 0.02
- 1 L/min flow rate is slower than modern hollow fiber filters
