An enhancement water system to produce a serving of enhanced filtered water is described. The present system describes a faucet mount water enhancement system that includes a housing with an inlet and an outlet, a source of water at the inlet, and a filter component within the housing. Source water is converted into treated water as it flows through the filter component under the influence of pressure. The housing further includes an outlet for outflow of treated water. A first enhancement module is disposed outside the housing adjacent the outlet and the first enhancement module is effective to dispense a desired amount of a first enhancement for use in combining with treated water dispensed from the outlet.
