Carbon Filter holding tank

A Carbon Filter acts as a valuable improvement to a holding tank vent pipe, effectively reducing the scent of rotting sewage. The activated carbon in the filter absorbs and converts the odors produced by your holding tank

Note: The Carbon Filter is not a substitute for good ventilation of the holding tank. It is designed to remove excess odour from a properly functioning holding tank. Holding tanks require good ventilation to ensure aerobic decomposition. Anaerobic decomposition due to lack of oxygen is the major cause of holding tank odour through H₂S production (rotten egg smell).
