    Abstract: A water filtering device includes a filter element and telescopically interconnected inner and outer cylinder units. Each of the inner and outer cylinder units has an open inner end and a closed outer end. A first space is formed in the inner cylinder unit. The filter element is disposed within the inner cylinder unit, and is adjacent to the inner end of the inner cylinder unit so as to define a second space between the filter element and the outer cylinder unit. The outer cylinder unit is movable on the inner cylinder unit, such that the outer ends of the inner and outer cylinder units are moved toward each other, thereby forcing water to flow from the second space into the first space through the filter element.
