Abstract: A toilet odor removal system is described, wherein malodorous air in the bowl of the toilet is evacuated by suction through a tube and into the sink drainage system. The system may be used in the construction of new toilets, or may be easily adapted for sale as a kit to retrofit existing toilets. An intake tube may be located under the toilet seat, in connection with a suction device. The suction device may be coupled to an exhaust tube which connects to the sink drainage system below the p-trap of the sink The exhaust tube may also have a one-way check valve to prevent odors from the sewer system escaping into the ambient air of the bathroom. The odor removal system may also have an automatic means of turning on, such as a sensor or a pressure-activated switch.
