A fluid purification system comprising: a first filter comprising a particulate filter, and having an inlet and an outlet; a second filter comprising a reverse osmosis filter, and having an inlet and at least a first outlet; a reservoir to hold fluid , the reservoir having an inlet, and an outlet ; a first line coupled to the inlet of the first filter ; a second line coupling the outlet of the first filter to the inlet of the second filter , the fluid to flow through the second line from the outlet of the first filter into the inlet of the second filter ; a third line coupling the first outlet of the second filter to the inlet of the reservoir , the fluid to flow through the third line from the first outlet of the second filter into the inlet of the reservoir ; and an ozone source coupled to the reservoir to release ozone gas into fluid held in the reservoir , wherein fluid enters the fluid purification system via the inlet of the first filter and exits the fluid purification system via the outlet of the reservoir , characterized by the reservoir containing a baffle transecting the reservoir , the reservoir having the inlet above the baffle , and the outlet below the baffle , the ozone source being coupled to the reservoir to release the ozone gas below the baffle , the baffle having a ridge or ridges around an underside of a periphery of the baffle , the ridge or ridges extending toward downward toward a bottom surface of the reservoir to trap a portion of the ozone gas along the underside of the baffle , an opening provided between a sidewall of the reservoir and the periphery of the baffle to allow passage of fluid from an the inlet-side of the baffle to the outlet-side of the baffle . a first filter comprising a particulate filter, and having an inlet and an outlet; a second filter comprising a reverse osmosis filter, and having an inlet and at least a first outlet; a reservoir to hold fluid , the reservoir having an inlet, and an outlet ; a first line coupled to the inlet of the first filter ; a second line coupling the outlet of the first filter to the inlet of the second filter , the fluid to flow through the second line from the outlet of the first filter into the inlet of the second filter ; a third line coupling the first outlet of the second filter to the inlet of the reservoir , the fluid to flow through the third line from the first outlet of the second filter into the inlet of the reservoir ; and an ozone source coupled to the reservoir to release ozone gas into fluid held in the reservoir , wherein fluid enters the fluid purification system via the inlet of the first filter and exits the fluid purification system via the outlet of the reservoir , characterized by the reservoir containing a baffle transecting the reservoir , the reservoir having the inlet above the baffle , and the outlet below the baffle , the ozone source being coupled to the reservoir to release the ozone gas below the baffle , the baffle having a ridge or ridges around an underside of a periphery of the baffle , the ridge or ridges extending toward downward toward a bottom surface of the reservoir to trap a portion of the ozone gas along the underside of the baffle , an opening provided between a sidewall of the reservoir and the periphery of the baffle to allow passage of fluid from an the inlet-side of the baffle to the outlet-side of the baffle . <EOS>
