The present invention generally relates to a ventilation system for a toilet to discharge odorous air from a toilet cavity of the toilet through an exit before the odorous air escapes from the toilet cavity. More particularly, the present invention relates to a toilet ventilation system for collecting the odorous air from the toilet cavity, transporting such through air pathways thereof, and discharging such to the exit. The present invention also relates to a toilet ventilation system for collecting the odorous air from the toilet cavity, removing at least a portion of odorous substances contained therein, and returning or recirculating a substantially odor-free air into a space in which the toilet is placed. Such a ventilation system of the present invention may be incorporated into various toilets in various embodiments such that, e.g., at least a portion or an entire portion of such a ventilation system may be embedded into the toilet or its parts, movably coupled to the toilet or its parts, detachably coupled to the toilets or its parts, or fixedly coupled to the toilet or its parts. Accordingly, the ventilation system of the present invention may be incorporated into a new toilet during its manufacture and/or may be arranged to be retrofit into an existing toilet. In addition, the toilet ventilation system of this invention may be arranged to ventilate a single toilet or to ventilate multiple toilets.
