Abstract: A drinking utensil having a longitudinal axis has an elongate body having a first end and an opposing second end spaced from the first end along the longitudinal axis. The elongate body defines a lumen therethrough from the first end to the second end. A filter body can be coupled to the first end of the elongate body. The filter body has a housing defining at least one side opening and a top opening that is in communication with the lumen of the elongate body. The filter body has a filter (e.g., a mesh filter) extending across and covering the at least one side opening of the housing.
