I used before a mini Katadyn filter and since I sold it because this model is really perfect. it has advantages over its predecessor: -Many Smaller and much lighter. -The filtration is becoming more easily and quickly (with Katadyn it really kept the chore!) -The Announced longevity is enormous. -The Price is really mini compared to the filters of the Swiss manufacturer. -L'entretien Is very easy. I used it during a mountain hike and I have drunk only water torrent or cast snow without feeling any trouble. I really had the chance to sell my old Katadyn filter that was used can at a good price because I think of this article make deprecated ..!
