Abstract
An air odor removal system with sewage or septic plumbing attachment removes odors from a stand-alone structural housing, such as a litter box or toilet bowl. The air odor removal system includes a first odor conduit assembly that is fluidly coupled, from one end, to the structural housing, and from an opposing end to an air mover device that creates a vacuum in the first odor conduit assembly. A motion sensor detects a motion event at the structural housing, and signals the air mover to power on. A second odor conduit assembly carries the odor from the air mover device to a one-way valve. A sewage plumbing conduit carries the odor from the one-way valve, and fluidly couples to a sink and a sewage storage, where the odor is finally discharged. The sewage plumbing conduit comprises a generally U-shaped pipe that restricts the odor from flowing to the sink.
