This citrus-scented InSinkErator® Bio-Charge® cartridge replacement for Evolution Septic Assist® disposers is a cost-effective enzyme treatment. Bio-Charge® contains a natural microorganism that helps break down food waste and a citrus scent to help control odors from the sink and drain. Bio-Charge® is only for use with the Evolution Septic Assist disposer and will last three to four months with average use. One cartridge of Bio-Charge® equals four bottles of other septic treatments.
