Pros & Cons
What We Like
- Incredibly affordable at around $20 — best value per gallon filtered
- Only 2 oz — among the lightest filters on the market
- 100,000-gallon filter life is virtually unlimited for most users
- 0.1 micron absolute filtration removes 99.99999% of bacteria
- Versatile mounting — works inline, with pouches, or on bottle threads
Watch Out For
- Noticeably slower flow rate than the Sawyer Squeeze
- Small 16 oz pouch is less durable and harder to fill than 32 oz options
- Flow rate degrades significantly without regular backflushing
- Does not remove viruses — not suitable for international travel
- Must protect from freezing or hollow fiber membrane is permanently destroyed
