Timothy T. ★★★★★

Installed this before a week-long trip and the flow rate is noticeably better than my old clogged filter. Clean water every time, no fuss.

Sebastian O. ★★★★★

Swapped in this replacement filter before a three-day backcountry trip and the flow rate was noticeably better than the clogged one I'd been nursing along. It screws in tight with no leaks and the water tasted clean the whole time.

Edward J. ★★★★★

Replaced the old microfiber on my gravity setup before a three-day trip and the flow rate was back to feeling brand new. Threaded on tight with zero leaks, which was my main worry.
