US 2013/0277290 A1 · PORTABLE WATER FILTER

Abstract

A portable water filter is disclosed. A portable water filter may filter water that enters through a first opening disposed toward a first end of the filter, where the water may pass through a filter element and exit the filter through a second opening disposed at or toward the first end of the filter. The first opening may be defined in a surface of the filter that is free of openings toward a second end of the filter. As such, when the filter is inserted into an opening or outlet of a bottle, more of the water in the bottle may be filtered and drained with reduced aeration as the first opening in the filter is disposed toward the opening or outlet in the bottle. The portable water filter may enable the flow of water through the filter element to be more uniform across the length of the filter element.
