  • How often should I replace the Litter-Robot 4 Carbon Filter?

    For optimal odor absorption, we recommend changing the carbon filter every month. Replacement frequency is up to you and your cats' usage patterns. To eliminate litter box odors, consider replacing the carbon filter with OdorTrap® Packs, which use plant-based oils to attract, attach to, and destroy odor molecules with natural chemistry.
