With a two sided sticky strip, attach this LARGE charcoal desiccant to one side and the other side to the inside of the lid or into a builtin pouch. The charcoal absorbs odors that might try to escape and will absorb any odors that remain after a bag is thrown out. It is really nice when you open the PooVault and it is fresh and ready to absorb more icky smells.
Each plastic envelope comes with a sticky strip and 5 desiccants.
The larger desiccants are 3.5" long and have twice the amount of charcoal than the smaller desiccants. If odor is a concern, this is the way to increase your protection.
