I would like to know if there is any screen to use as a pre-filter so the media does not clog as quickly. I was thinking of possibly using a 3M face dust mask. I was also thinking that if you would fill a pot and let it sit for an hour to let the bigger particles settle, then fill the Basecamp, would that allow the media to last longer? |

quote Scout64: "My conversion is done! Thanks. Seems to work well. " In case you are interested in installing a carbon/charcoal filter, I've been able to find two that will work on the gravity systems: Platypus Gravity Works Carbon Filter Katadyn Carbon Filter Both are around $20 I think. The platypus filter gets thrown away and the Katadyn unscrews and can be recharged with new carbon media. I also found a MSR Sweetwater Siltstopper pre-filter that looks interesting. It can be backflushed like the Sawyer filters and purifiers. At $20, it might be worth installing one if it increases the life of the Sawyer |

Carbon/charcoal filters remove some chemicals that the filters/purifiers do not and are known (from what I've read) to improve the taste of the water. I suppose they can also remove some larger particles of stuff if they were installed in front of the filter/purifier, but that's not what I have one in my setup for. |

quote SaganagaJoe: "OK - I bought the replacement kit Katadyn offers - $64.99. That's not that much less than I paid for the bag but I digress. I'll be trying it out and holding them to their one-year anti-clog promise. I just don't feel ambitious enough to try the conversion. We'll see how they do and I'll report back. " Update: I installed the replacement kit on my Basecamp bag and it fit perfectly and flowed well for the test. We'll see how she likes a little water from Saganaga in August. A tad expensive for my liking but I didn't feel comfortable enough doing the conversion. |

I blasted water into the filter and watched a big green stream come shooting out of the inlet hole. Worked like new after that. I'm sold on the mini. |

Just make your own from scratch. It was a really fun project. |

Here is my rig. I got tired of trying to find flat rocks to build a rise for my Nalgene bottle. I bought a Nalgene canteen for my solo trip and rigged it to hang from a branch down to the spout. Problem solved. |

Sometimes, I want the ability to pump the water rather than wait for gravity. I know there are bags that you can squeeze. But I already owned the hiker and the hiker will provide unlimited water without having to refill a bag... |

Thanks for the confirmation. Since I also own and use a pump unit I will be able to use the siltstopper so its not a total waste of money. |

The only water restriction you will ever have now will be the Sawyer filter itself. Instead of this: You are left with this: |

quote OldFingers57: "I talked with a Katadyn sales rep at Midwest Moutaineerings Spring Expo last year and he said the new ones won't clog but failed to explain to me what they changed to prevent it. " I'm happy to hear that but skeptical. I did have good service from Katydyn. I made them replace several of the failed filters. I explained that is was completely unacceptable for a piece of survival equipment to fail this way. I was filtering very clear, clean water. But the filters still failed after a day or so. If it truly was a survival situation, I would have been in trouble. Katydyn did relent and did replace the filters. But they were very adamant that they were just replacing out of the goodness of their hearts. They were clear to note that it was NOT a warrantee issue. I'm not sure of the significance of that but they wanted to be very clear. I still have Katydyn Hiker that I like. I would love to have more reliable filters for it. |

If you already have put out the $ for the Katadyn Base Camp and don't want to trash the entire system and start over with something entirely new, you have to do the Katadyn filter mod pictured above, to continue using the bag. The bag on the Katadyn Base Camp will only work if you have a Katadyn filter or modified filter. It is the largest and easiest to fill of any gravity system bags that I've seen. Well worth the trouble to do the mod. You only have to do it once with an old used filter. After the mod, you only have to do maintenance on whatever brand of inline filter you add to the modified system. I like the Sawyer Point Zero Two Purifier, but there are others. I also add an inline charcoal filter to improve the taste. |

If it needs pressure from a pump unit like my Katadyn Pro-Hiker I'll use it in that application. My fingers are crossed that it will work with my gravity-fed setup. |

quote OldFingers57: "Just go and buy an MSR, Sawyer or Platypus gravity filter instead and not have to mess with all of the conversion stuff. Those brandss don't have the problems like the Katadyn does. " I don't know much about the other filters. But their bags look much smaller. It also looks like their bags are hard to fill. The base camp has a huge bag that is very easy to fill. Am I misunderstanding that? |

I was very disappointed and called Katydyn. They are replacing both of my bad filter cartridges. I can use them in Alaska or maybe the BW in the spring. But... Now, I don't have a used filter to cut up to convert my basecamp. Does anyone have a used filter? I'd be happy to by it from you. |

Which kit do they offer? Is it just the same as a replacement filter? I see that the new Base Camps have a quick disconnect at the discharge of the filter. I have a couple replacement filters on hand now so I am set for a couple trips, or am I? Thanks and keep us Katadyn users poster. |

Here is a link for the 10L filter. The description at Rutabaga has this interesting comment: "One-Year AntiClog™ Guarantee on the filter element. Katadyn warrants your Ultra Flow Filter™ Element to be free from defects that cause the filter to clog. " They also sell a kit to convert the old style 6L basecamp filters to the new filter. Filter |

But i will use the bag and convert the filter as others describe in this thread. The idea of a base camp bag filter is great. The actual filter on the Katydyn filter is the problem... |

I used it this spring and the Katydyn worked well. I took it again last week. I brought my Sawyer along just in case. Sure enough. After about a few days, the katydyn slowed to a drip. I did a field conversion to the katydyn bag with the Sawyer filter. System worked great for the rest of the trip. |
