Water bottles and flavor tablets for use therewith. The water bottle includes a container having a closed end, an open end, and a removable lid selectively coupleable over the open end of the container. A straw is disposed through the lid, or attached to the lid. A filter may be disposed within the straw, the filter removing impurities from water as it is drawn from the chamber through an opening within the straw, through the filter. A flavor tablet (e.g., a dissolvable solid including a flow channel disposed therein, or defined between a perimeter edge of the tablet and the straw or spout) can be placed within the straw or spout of the water bottle, downstream from (e.g., above) the filter so that water drawn through the straw passes first through the filter (if present), and then around or through the flavor tablet, flavoring the water drawn therethrough.
