Abstract: Some of the present containers include a bottle defining a mouth in fluid communication with an interior volume, a cap configured to at least partially cover the mouth and defining an outlet in fluid communication with the interior volume, and a filter assembly configured to filter liquid communicated between the interior volume and the outlet, the filter assembly having a first end, a second end, and a housing extending between the first and second ends to define an interior passageway configured to contain a filter having an upper end cap defining an opening, a lower end cap, and a filter media extending between the upper and lower end caps. In some containers, the filter assembly is configured to be coupled to the cap with the opening in fluid communication with the outlet. Some containers include a straw configured to be coupled in fluid communication between the outlet and the opening.
