A portable fluid ozonation apparatus includes a container for treating and storing fluid, a filter that attaches to the container and an ozone generator. In use, a fluid is dispensed into the container and optionally passed through the filter. At this point, power is supplied to the ozone generator which operates for a period of time necessary for disinfecting the fluid. Additives and post filters can be utilized in conjunction with the ozonation apparatus in order to obtain sufficient purified fluid within a short time frame.
