Another thread got me to thinking again - I still need a reliable water filter. I am not a hiker but had decided on the Katadyn Pocket Filter, but many knowledgeable people on here with much more experience than me seem to like the Berkley. Does anyone have a specific Berkley model they prefer? Any preferences overall? The Berkleys that filter through 5 gallon buckets would be too bulky to haul but maybe there are recommended alternatives posters have personally used. My situation: *Looking for the "Glock" of the water filter world - RELIABLE. *Looking for drinking water to support 2 adults minimum. *Must be portable for extreme reliability *Able to filter many gallons before filters exhaust themselves. *Cost is not my first concern - the cry once theory. THANKS IN ADVANCE.
