Pros & Cons
What We Like
- True purifier — removes viruses, bacteria, protozoa, chemicals, and heavy metals
- Fastest purification: 24 oz of clean water in 8 seconds
- No sucking, squeezing, or pumping — just press
- Doubles as a durable travel bottle
- Ideal for international travel where viruses are a concern
Watch Out For
- Cartridge life is only 250 liters (65 gallons) — expensive per gallon
- 15.9 oz is heavy compared to squeeze filters
- 24 oz capacity limits volume for group use
- Press mechanism requires moderate hand strength
