Water treatment apparatus including an iodine resin purification bed suppported in a walled structure and mounted upstream of an active carbon filtration bed. In one disposable cartridge construction, a replacable, toroidal sediment filter surrounds the purification chamber which concentrically projects from the upstream end of a larger diameter active carbon bed. In another construction, the purification bed includes a directionally permeable, replaceable, pointed housing which insertably mounts within the carbon bed. In another construction a portable housing contains a purification bed within a surrounding carbon bed, and receives water from faucet coupling means and includes a nozzle. In still another personal construction, a purification cartridge mounts between a pressurizable collector and canteen.
