The ultralight Katadyn BeFree water filtration system is a lightweight, filtration system that can go with you on any adventure. It's as easy as filling the flexible reservoir with water and immediately drinking clean water at a rate of up to 2 liters per minute. The BeFree will output 1000L of water (depending on quality). The Katadyn BeFree removes bacteria, cysts and sediment with its pore size of 0.1 micron. 100% PVC and BPA Free.
The Katadyn 3.0 Liter can be used as a gravity system with a little bit of twine or paracord.
To clean the EZ-Clean Membrane, simply shake or swish the filter, no back-flushing required.
