As with most great chal­lenges, the win­ner is the one most suited for the fight. Both media types are highly effi­cient at remov­ing chlo­rine, but even this gets com­pli­cated. Also, there are dif­fer­ent types of KDF and car­bon fil­ters, which makes it even more chal­leng­ing to choose the cor­rect fil­ter. I will try to shed some light on this some­times con­fus­ing and even heated dis­cus­sion. (Yes, water folks can actu­ally get uptight about this issue so fire away in the com­ments sec­tion.) I will walk through the most com­mon uses of each media type and offer some guid­ance on which wins each challenge.
