Keep your home smelling fresher with a 6-pack of pre-cut activated carbon replacement filters compatible with Litter-Robot 4. Made from high-density activated carbon, these filter sheets help absorb and neutralize unpleasant litter drawer odors while supporting cleaner airflow around the unit. The material is soft, natural, non-toxic, and odorless, so it is safe to use around pets. Replacement is quick and tool-free: remove the old filter, install the new carbon sheet in the filter cover, close the bonnet, and reset the system (use the unit controls to enter the replace-filter position if needed). Ideal for routine litter box maintenance in homes that want better odor control; for best results, replace about every 1 month, providing up to 6 months of supply depending on usage.
