This is my nomading travel
This is my nomading travel companion, not just my backcountry water treatment. Warding off microbiome disasters wherever I go; rural Mexico to remote Nepal, and everywhere in between (including sketchy airbnb tap water).

One of the best filters available
- Familiarity:
- I've put it through the wringer
Never have to clean or back flush. Don't have to worry about anything making you sick. I have used Sawyer styles and katadyn, this filter is in a league of its own. This will be the last filter system I ever buy.

Nice upgrade
I bought this after using MSR's regular gravit flow system for years. It's great to have the self-flusing feature, instead of having to back flush the old model. Very fast.
