Abstract
A liquid storage and dispensing device with a filter for removing minerals and a UV light source for killing pathogens existing in a liquid. A liquid is introduced into the device via the inlet. The liquid passes through the filter into a collector. The filtered liquid flows from the collector through a thru passage into a UV chamber. The UV light source emits UV rays through a UV transmissive wall into the interior portion of the UV chamber. Exposure to the UV light kills pathogens present in the filtered liquid. Substantially purified liquid can then be dispensed from an outlet.
