Yeah, I’ve read that one, several times. I have a copy on my files. Good stuff.
It seems that even that little Britta pitcher filter worked pretty well. I’m guessing a good carbon block would be better. How much chloramine is too much?
I have been using a tiny amount of Campden in my filtered water. A pinch would be enough, wouldn’t it? Something like 20 mg? I really can’t tell the difference.
I don’t know why carbon wouldn’t be a catalyst. It’s in the reaction, but not in the final product.
