Product Reviews

Quick and ready pump
A sure choice for clean backcountry water filtration.

I've had one of these for years, and it's an out of the box winner and a champ even after years in the pack and on the trail.

It's a simple design (tube and pump) isn't exactly comfortable to handle when filling an outing's bottles and bladders, but I've never had an issue with the water quality (zero sediment and coloration, plus a clean taste). And that's what's important. If it ain't broke, don't fix it. I hope this filter stays in the line for many more years to come.

Admittedly, I used this longer than was recommended without cleaning the filter, but even then, I noticed nothing that would indicate a deterioration or its ability or of the quality of water produced. Clean from day one, and after years.

The breakdown and pack up design isn't completely intuitive, but easily understood, and once discovered, even appreciate for its simplicity (minimal moving parts and junctures). Review by Polycamperous
