"good filter" - Review of Katadyn Exstream Purifier Bottle

A nice filter inside a bottle. I only had one problem with it. The first was that the bottle itself was filled with paper, kind of like when you buy shoes. So I just took out the paper, but the problem was the actual filter had two pieces, one of them was inside the paper, and I did not realize it until I read the outside of the bottle when I was miles away from civilization. So half of the filter did not come on my trip, though the other half worked great and I did not get sick. What a great thing that you could lose half of it and it still works perfectly fine.
