No integrate that into a water system is not as easy as to filter a bottle of water, especially if you want it to flaw in a quick pace. In this case also you better use glass instead of wood to see what is happening inside the filter, to change something if needed, like the cotton. Also consider using stones in that case. But i believe you can come up with something. Still i think producing real active carbon is more difficult, at least for me.
