Key Benefits — How this solves real problems
- Removes common bacteria and protozoa: 0.1 micron hollow fiber membrane blocks pathogens that cause illness in backcountry and travel scenarios.
- Better taste and odor control: Carbon fiber improves flavor and removes unpleasant odors so water is drinkable immediately.
