  • How often should I replace Litter-Robot carbon filters?

    For optimal odor absorption, we recommend changing the carbon filter every month, but replacement frequency is up to you and your cats' usage patterns. If you use scented litter, we recommend changing the filter more often as it will also absorb the litter scent.
