Reduces litter smell
I didn't know this was in the litter robot till Amazon suggested it. The robot started to smell more often and I didn't know why. Replaced the filter after 8 months and it does help the smell. The litter robot has such low maintenance this is easy to take care of.

LR4, I double their life.
After having some issues with one my LR4 globes, I started cutting these in half. I use half in the filter cage and in the other half I place a Fresh Breeze packet. This works great! I have 2 LR4s, 6 cats, and this combo keeps the globe free for rotating and smells great as it cleans.
