Acting as a valuable improvement to a holding tank vent pipe, a Carbon Filter effectively reduces the scent of rotting sewage, as well as absorbing and converting the odours produced by the holding tank.

Please note that a Carbon Filter is not a substitute for good ventilation of the holding tank, and is instead designed to remove excess odour from a properly functioning holding tank. Holding tanks require good ventilation to ensure aerobic decomposition, which arises due to a lack of oxygen, producing H₂S and causing holding tank odour.
