The chemical composition features advanced odor-eliminating technology that promises to control unwanted smells for up to 7 days, which is quite effective for longer trips. The orange scent adds a refreshing touch, replacing unpleasant odors with a pleasant citrus fragrance.

When it comes to waste breakdown efficiency, these drop-ins excel at breaking down waste and toilet paper, which can help prevent clogs and improve sensor performance in your tank.
