I'm at about 3 years and it's still going fine. When it even hints at slowing I swish it in the stream. I tend to swish it every time at the end of my evening water filtering sessions. It's used almost 100% on clear flowing high country creeks with some use on cattle tanks in AZ NM elk country. I make sure to store it wet. If they dry out they can have much reduced flow until fully wetted again which can take an overnight soak. I noticed Backpacking Light (Ryan Jordan owner/founder) has recently moved to recommending the Hydrapak. He claims better life and less slowing or clogging. When it's time to replace my BeFree I'll probably buy the Hydrapak since they are directly compatible.

Hydrapak Water Filters • In 2022, I started experimenting with Hydrapak filters. By the time my summer trips in 2023 rolled around, I've now replaced all of my Befree, Platypus Quickdraw, and Sawyer Squeeze filters with Hydrapaks. They are faster, clog less, and compatible with 42 mm bottles, which are my favorite. On our High Sierra trip, we used a combination of the
42 mm Filter Caps and the
6 L system that we used as a group gravity filter in camp. Both performed exceptionally well, even when we could see that the filter media was visibly dirty. The gravity filter has the most functional valve we've ever used, as well, with lock off and lock on functionality. Today on a day hike I used the 42 mm filter cap with the
500 mL Ultraflask and I can see this becoming my new favorite day-hiking and on-the-go water kit.
