Overview
Litter Box Odors Away
The Litter-Robot 3 Carbon Filter can be easily removed and replaced when cleaning the drawer. For optimal odor absorption, we recommend changing the carbon filter every three months, 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 the filter will also absorb the litter scent. Note: The Litter-Robot 3 Carbon Filter is not necessary for the unit to function.
