Thanks for the link, Garden. This is helping to clear things up a bit. I was sort of thinking about a system that you set up in your pack as you hike, but maybe that is totally unneccessary. I suppose I could stand by a nice little stream for a few minutes while gravity does its work... As I mentioned, I really love the taste of my Combi filter, do you think a carbon prefilter could be added to this model?
