A water dispenser supports a bottle having a neck closed with a holder accommodating a water filter. The cap member has an inwardly converging sleeve complementary to and engageable with the outer surface of the filter to retain the filter on the bottle neck. An air bleed hole in the bottle is located at a selected height relative to the exit openings of the filter to control maximum flow rate of fluid through the filter.

1. A bottle and a filter for storing a liquid usable with a liquid dispenser wherein the bottle is inverted on the dispenser to provide the dispenser with a supply of filtered liquid comprising: a bottle having a side wall with a first end and a second end, a bottom wall joined to the first end of the side wall, a top wall joined to the second end of the side wall, the side wall, bottom wall, and top wall surrounding a chamber for storing liquid, a neck joined to the top wall having a passage open to the chamber and the dispenser, a filter for removing contaminants from the liquid, said filter including an inlet opening located in the chamber to allow liquid to flow from the chamber into the filter, an outlet opening located below the inlet opening to allow liquid to flow from the chamber into the dispenser, and filtering material located between the inlet and outlet openings for removing contaminants from liquid flowing through the filtering material, said filtering material having an internal resistance to the flow of liquid through the filtering material, a holder releasably mounted on the neck for retaining the filter and positioning the filter in the passage of the neck operable to remove contaminants from liquid flowing from the chamber through the filtering material into the dispenser, and hole means in the top wall of the bottle exposed to external air for allowing air to flow into the chamber of the bottle during the flow of liquid from the chamber through the filtering material into the dispenser and preventing liquid from leaking from the chamber of the bottle through the hole means due to the internal resistance to the flow of liquid through the filtering material.
