Abstract
A water treatment unit includes a base and a disposable, plug-in cartridge. The cartridge contains a pair of hollow cylindrical, porous, solid water treatment elements designed to treat water flowing radially through their walls. The cylindrical elements are mounted so as to act in parallel, thereby achieving the advantages of a long, thin-walled element in a compact configuration.
