A filtering unit for drawing liquid from a container by means of suction through a standard detachable straw. A standard drinking straw is attached to my filter over a protrusion on the filter surface. Suction applied from the protrusion through a straw, draws liquid through perforations on the bottom of the filter, then passing through the filter material which may be made of bone activated charcoal, carbon, fiberous material, or any other filtering agent, up through straw and into users mouth. Perforations, gauze, cotton, or anything capable of stopping filter material from entering straw and users mouth are placed at the base of protrusion and bottom of filter, thus encasing filter material in a conceiled compartment so as not to let filter material escape from shell and yet allow liquid to pass through when suction is applied.
