This trusty steed has been on the AT and countless back country excursions and has performed great. As the filters starts to clog you will notice the pump harder to push. It takes many liters getting to this point but is the sign to swap the filter. The prescreen works OK but I would wrap a bandana or use a pot to filter from so sediment can settle. They have a Nalgene adapter and that is sweet but overkill for bikepacking. I have put three filters in mine and just relube all the moving parts with food grade grease. She is good to rock. Occasionally I will get an air lock and it will not pump. Don’t Fear. Just unscrew the filter and get some water in there (1/3 full) put filter back on and start pumping. It’ll give it a prime and then she is running. I usually spit out the first few strokes anyways to clean the lines.
This design has been around for almost 20 years and not much has changed except the T handle pump is now a flip around handle (less obtuse for sure). Only filter I have ever had to own. Weight is sorta a penalty but it will always work when needed. No batteries required and does not taste like iodine or chlorine.
It’s not the fastest but it is very reliable and very durable. Never leave home without it.
I agree with both the above reviews. I have owned mine for 4-5 years now and it has never let me down. I dont even worry with carrying a ton of water if there are streams on my map. Great little filter I have replaced the filer in mine twice in the years I have owned it. The top cap fits directly into the top of my camelbak bottles. i never leave home without it. Simple design and easy to use. You can’t go wrong with it.
This looks exacly like a PUR that I bought 2 decades ago. I wonder if it has the same filter. I used the PUR to drink out of the Missuri with no ill affects. It seams that there are certain comforts that are worth the extra weight.
A trusty steed! And yes, this filter is the same as the PUR HIker (Katadyn bought PUR). I own the PUR model and the Katadyn filter fits and works perfectly. I have used this filter for somewhere near 20 years. I agree with wrapping a bandana around the prefilter. This captures a lot of bigger particles and your filter will last longer. This filter really is a solid performer. Its not the smallest or the lightest but its not unweildy either. I have never found a need to replace it with something else.
