Pros and cons
- Purifies a full 24 oz in about 8 seconds
- Removes viruses, bacteria and protozoa in one step
- Also filters chemicals, PFAS and heavy metals for better taste
- Cartridge rated for 65 gallons before replacement
- Pressing the cartridge down takes real arm strength
- Bulkier and heavier than straw or drop-based filters
- Can be hard to pull apart for cleaning
Performance notes
The purifier uses a press mechanism instead of a pump or gravity system: water fills the outer bottle, the inner cartridge presses down through it, and purified water collects in the inner chamber ready to drink. It removes viruses, bacteria and protozoa while the cartridge also adsorbs chemicals, VOCs, PFAS, heavy metals and odors. Because the cycle relies on body weight pressing the cartridge, it works best on solid ground rather than seated in a canoe.
