Litter-Robot 4: Carbon filter installation guide

Litter-Robot 4 is equipped with a flexible carbon filter pad that is installed on the outer bottom area of the globe. This filter sits directly over the waste drawer to absorb odors. 

The carbon filter is not required for the unit to function. The OdorTrap® Packs may be used instead of the carbon filter.
