The MSR Miniworks Water Filter
This is without a doubt the best filter for anyone planning on attacking a major hiking trip. The bottom screws onto my MSR Drommlite bag and my Nalgene bottle. It is long lasting and easy to clean if you ever get to that point.You only have to clean the outside of the filter, and only use clean water to do so. Soap is a cloggy substance and will be unforgiving to the carbon granules inside the element.
