A filter basket and filtration media for an inverted bottle type water dispenser which is disposed below the inverted bottle, depending from the collar of the water reservoir into the water reservoir and receiving the neck of the bottle, so that all the water discharged from the bottle passes through the filter basket in a downward direction. The filter basket has an inverted conical upper section which funnels all the water which is drained from the bottle to a filtration compartment at its lower section. The filtration compartment remains submerged in water. The filtration compartment contains the filtration media and discharges the filtered water therefrom directly into the water reservoir. Air released in the spigot when it is opened rises upwardly through the filtration media to be received in the bottle. The filtration media comprises an aluminosilicate gel with pore sizes in the range of sixty to two hundred and fifty Angstroms which provides for rapid flow of water and air therethrough. Other filtration media may be used in combination, such as activated carbon. The filter basket and filtration media is composed entirely from microwave-safe material for sterilization in a conventional microwave oven. |
