Abstract: An improvement for toilet assemblies wherein an odor extractor device is connected to the overflow tube of the toilet assembly. The water supplied through a conduit to the overflow tube is discharged on a tubular member that is connected to an opening on the lateral wall of the overflow tube. A flexible sheet is mounted over the opening, on the internal surface of the lateral wall of the lateral wall of the overflow tube. The flexible sheet maximizes the suction applied to the bowl rather than the tubular member so that the gases typically associated with these excretory functions are extracted through the conventional drain apertures found in bowls.
