I have a pump filter...worked good....but SLOW! It is the katadyn hiker before katadyn bought the company. I recently got the Camelbak All Clear (a deal too hard to pass up). I just used it on a quick trip and it did great. I used it right next to the steripen my BIL owns and both did well. I probably did 7 gallons of water and the battery didn't really take a hit. Showed 3/4 after a long spell of using it, but then showed 4 bars on the one bottle I sterilized on the trip out. I personally won't go back to the pump. My FIL has a sawyer of some type and it does fine. Me I'll have some coffee filters on hand if there's lots of sediment. This last trip was a clear stream and no pre-filtering was done. I was very pleased with how it worked.
