Hi, I tried searching for "carbon" on FC but didn't find much. Was hoping to start a thread to incite discussion on carbon filters. I have never used one, so I was really hoping for a lot of feedback. What are pros/cons? What are the main differences between having one/not (taste, aesthetics, etc.)? Was it worth the price paid? Favorite manufacturer (if any)? Science-related articles? Does it remove any of the potency of the product?
