Hiya,
I'm considering adding a filter to my incoming water (fed by a well). I get
iron bacteria every now and again but would prefer not to use chlorine (I'm
on a septic) so was considering a carbon filter as this is what was
recommended to me by the well company. Anyway, it seems there are a number
of options available and I'm just not sure which one to go with.
Specifically, is something like this adequate:

or should I be looking at something a bit more "industrial" like this?:

Thanks for any advice you may have.
Cheers,
