Abstract
The point-of-use water treatment system for treating water to be dispensed from a container includes a filter media positioned adjacent a water input opening of the container, through which water is filtered into the container. The filter media includes a water soluble disinfectant positioned thereon or therein, with the preferred disinfectant tetraglycine hydroperiodide, chloramine-T, or calcium hypochlorite. The disinfectant dissolves in the water as it passes through the filter, and reduces the biological activity of microbiological agents in the water. A point-of-use method of the present invention which reduces microbiological contamination in a predetermined volume of water to be dispensed from a container which utilizes a filter media containing a water soluble disinfectant impregnated thereon is also disclosed. The method includes the steps of positioning the filter media adjacent the opening of the container, filtering water through the filter media, dissolving the disinfectant in the water as it passes through the filter media, allowing the disinfectant to contact and deactivate microbiological agents in the water, and disposing of the filter media.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
