Carson wrote a review of Katadyn Micropur Purification Tablets - 30 pack on August 23, 2011
I used these tablets everyday while on a 3 month expedition through the Congo River Basin. Some days the only water I had to drink was rancid swamp water. But thanks to these tablets I never got sick once, even my Baka Pygmy porters fell sick on occasion and they've lived in the forest since birth. I still ran my water through a pump so dirt wouldn't get in my teeth. And always plan in advance, because 4 hours is a long, long time to wait when you're out of clean drinking water!
