Litter-Robot 4 Carbon Filters by Whisker, 12 Pack, Custom Fit Carbon Filter Pads for Litter-Robot 4, Absorbs and Reduces Litter Box Odors for Cleaner Smelling Home

These are So easy to use and they work well. Our LitterRobot 4 Never has an odor! They fit perfectly. These are a tremendous value!

Great filters to help keep the stink away in the litter robot. They fit perfectly, and easy to use and install.

We change our filter every time we change the litter and they come out moldy sometimes. This is every 3 to 4 weeks. They help hold the smell pretty well.

Switching these out made abig difference in smell. I will be doing that more often.

Produce was delivered as advertised and on a timely basis.

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.

I sort of set and forget my Litter Robot. About a year after purchasing it, I remembered… Hey! There’s a filter in this thing. It was disgusting. Do yourself a favor and order some spares to keep on hand.

I was needing to replace original litter robot 3 filters. These worked perfectly. They fit snug and keeps the odor down between box cleaning. Would recommend.
