Looking for Input on your favorite filtration system for 2-3 people?. Currently I have a Msr mini works ex? (Or similar... its 15 years old now) and a katadyn hiker pro. I also often pack a life straw. Usualy the areas i pack into finding water is simple and plentiful so I try to carry only 2 liters in a hydration bag and a nalgene bottle and replentish as needed. This saves pack/ carrying weight, the old Msr, even with new ceramic filter seems to take a while to push a few liters through so I picked up the katadyn. Just wondering if there's a faster more effective lighter method for water purification ( no tablets....cant stand the taste) ? Thanks
