Katadyn BeFree 1.0L Water Filter, Fast Flow, 0.1 Micron EZ Clean Membrane for Endurance Sports, Camping and Backpacking, One Size, 8018006

The Katadyn BeFree Water Filter System has received generally positive reviews from customers who have used it for camping, hiking and backpacking. One customer who used it on a 600-mile hike said it held up great, while another used it on the Appalachian Trail and Pacific Crest Trail and found it easy to use and efficient. However, one customer reported that it leaked, rendering it useless on the trail. In terms of specifications, customers have reported that the filter is easy to set up and use, and that it is quicker than pump-type filters that can sometimes suffer from plugging pumps and loose hoses. The water filter system folds down to about the size of a wide-rim double shot glass and comes with a very resistant bladder. In terms of maintenance, users are advised to replace the O-ring frequently and to rinse the flask and filter with clean water after each use. Additionally, they should let the components fully air dry between uses to prevent mold and fungi from forming.
