A Must-Have for Litter-Robot Owners!
I recently purchased the Biodefensor 8 Pack True Carbon Filters for my Litter-Robot 3, and I am beyond impressed with the results! These filters are a game-changer. The upgraded thicker charcoal does an exceptional job of trapping odors, which means my home stays fresh much longer than before. I also appreciate that they are made in the USA, non-toxic, and safe for my pets. Installation was a breeze, and I noticed an immediate difference in how well these filters control moisture, keeping everything dry and odor-free. If you own a Litter-Robot 3, these filters are a must-have. Highly recommended!

Good as expensive brand
They're fine. They work just as well as the expensive brand. I still have to empty the poop every time my cats use the litter robot since I think it always smells. Save money, but this cheaper option.

Not very thick
I had ordered filters from the company Litter Robot for our litter box. Those filters were thicker than these, so I have to replace the thinner ones frequently. These are much cheaper than Litter Robot and they are okay if you are in desperate need, otherwise I would order the thicker filters.

Smells are at 60% reduced
I have the original WIFI litter robot and bought these to get a little more longevity from the unit. It’s not emptying quit as well as it used to and the tray just seems to hold less in volume and smell . These helped a lot to filter the smell that was becoming burdensome. The original filter isn’t quite as thick as these replacements.
