Yeah, got one and carry it but the funny thing is I've never used it. Always seem to make it through the day and usuallyjust boil up my needs.
Usually there is at least 4 of us when we go backpacking and my pot is a single serving one. One other person might have one as well. The filter is nice to just take the bladders/bottles down to the water source and fill and go. Also nice to have when you need some water on the go and don't have time to stop and boil. Of course, boiling will save you some $$.
