A venting device configured to attach to a vent and to reduce malodors emitted from a vent includes a first end, a second end, and a center portion. The second end includes two holes into which a barrier is inserted. The second end also includes a protrusion and a ball configured to rest on the protrusion. When a disruption in air pressure occurs within the venting device, the ball moves upward from the protrusion to allow air to exit the device. The barrier prevents the ball from moving upward beyond the barrier.
