"Is water supposed to have a taste?" - Review of Katadyn Vario Dual Technology MicroFilter

This water filter was awesome for the first few trips. Pumping was easier than ever. Having a pumping action similar MSR models really eases the strain of pumping. Aside from that, I really noticed little difference from my PUR Expedition, or Katydyn Explorer. The last trip we took, we noticed a distinct taste in the water filtered from the Vario, and it was awful. After talking with some people, it would seem that the carbon can house a particular algae found in the High Uintas if it does not dry completely in between trips. I have to wonder if it is mostly my fault for not running some bleach through the filter, after the second to last trip, as I had done for all the others to kill anything left in there. The trips were so close together I did not think it would matter. With a new filter, and some extra carbon packages, we will give it another chance this upcoming season, and see if the problem is user error or an issue with the design.
