Brian ★★★★★

Took this on a three-day trek and it handled silty creek water without a single clog. The pump action is smooth enough that I didn't dread refilling at camp.

Victoria U. ★★★★★

First trip out, I filled it from a muddy creek and the water came out crystal clear with zero aftertaste—that alone sold me. The pump action is smooth and didn't tire my hand even after filtering two liters, which is more than I can say for my old setup. This is the last purifier I'll need to buy fo

Claire ★★★★★

Took this on a week-long trek and it handled every stream and muddy puddle I threw at it without a hiccup. The purifier is compact enough that it barely adds weight to my pack, which is exactly what I need for solo trips.
