Abstract: An exhaust hood system can include an intake located within a building, an output, a duct positioned between the intake and the output, the duct fluidly connecting the intake and the output together, a filter positioned within the duct, the filter emitting a liquid within a portion of the duct, a drain in fluid communication with the filter, and a chamber comprising a photosynthetic agent or a fungal agent. The chamber can be in fluid communication with the drain.
