As far as I know, the only reason they aren't used today is good ol' capitist enginuity figured out a way to make them disposable. But I bet there isn't quite the technology invested in the old canister filters as in the new disposables. Have you tried searching for information on Wicks, Perolator, Fram and some of the other suppliers' web sites? You'll probably find some info there I would think.
