An ozone supply module for supplying ozonated water to an appliance that typically includes: an appliance module housing having a water inlet; a water outlet; and an electrical connection for receiving electrical power; a proton exchange membrane cell positioned within the housing; and a water conveying system within the module housing and operably connected to both the water inlet and water outlet. The water conveying system is typically configured to allow water to flow through the deionizing resin and into contact with the proton exchange membrane cell. The module and the proton exchange membrane cell receive electrical power from a home appliance when the module is operably connected to the appliance. The module produces water that contains (dissolved) ozone to be delivered to a chamber within the appliance when the module is in the engaged position with the appliance. The appliance is typically a residential appliance.
