normal formatting for title would start with E: 25/09 which keeps it in line with other comps posted and used to help with sorting the board, but I'm not sure whether that works or is relevant anymore with new forum

It says in the text "The activated carbon in our cartridges absorbs nasties that affect the taste, like chlorine and heavy metals, whilst the ion exchange resin reduces the hardness and limescale that build-up in your kettle."
From this, I would say the answer is Activated carbon only. It doesn't say that ion exchange resin reduces taste affecting substances, only that it reduces hardness and limescale.
