Katadyn Hiker PRO Replacement Cartridge

Easy replacement...comes with replacement O-rings and silicone lubricant too. Well worth the price--you probably will want to stock up on a few of these, both for your regular outdoor uses and "just-in-case." Want an interesting internet search??? Go to your favorite search engine and input "municipal water supply contamination" and see what you get. Definitely worth your while to buy a good water filter (I use and recommend Katadyn) PLUS some spare filters.

I have the old PUR brand hiker pro and this filter the replacement for it. It is used in both Katadyn and older PUR Hiker models.

Overall, I think the quality of Katadyn filter is better than the older PUR brand, but neither of them lasted long. If you do extended backcountry trips, expect it to last about 2 weeks with 4 people using it. I do not trust the durability of ceramic filters so I stick with my trusty old PUR/KATADYN hiker which is easy to repair and rebuild with the kit provided.
