This review dives into why this cartridge is a smart investment for anyone looking to prolong their disposal’s life while keeping their kitchen fresh.

Key Features

• Citrus-Scented Enzyme Treatment: Infused with a refreshing citrus scent, the cartridge contains natural microorganisms that actively break down food waste inside your septic disposal.

Comparison with Similar Products

Compared to standard septic tank treatments or enzyme additives sold separately, the InSinkErator Bio Charge cartridge offers a more integrated and maintenance-free approach.
