KATADYN BeFree 1.0L portable water filter for safe hydration, with a filter life of 1000L. I purchased this and performed the initial filter priming and draining, but I have never used it. Although it is practically unused, I have drained the water once, so I have listed it as "Like New". The box has a slight tear. Please note that the box will be folded for shipping. - Brand: KATADYN - Model Name: BeFree - Capacity: 1.0L - Filter Life: 1000L Thank you for looking.
