Review: Perfect for litter robot 4 - I purchased these carbon filters for my automatic cat litter box, and they've worked very well. The filters fit properly and were easy to install without any modifications. works for litter robot for perfectly One of the biggest improvements I noticed was the reduction in litter box odors. The activated carbon seems effective at absorbing smells, helping keep the surrounding area fresher between cleanings. With multiple cats in the house, that's a huge benefit. The filters appear to be well-made and thick enough to last as expected. Having an 8-pack provides excellent value and means I won't need to reorder for quite a while.

### ⭐⭐⭐⭐⭐ Avoid the Stink…these work!
*by P***A on June 17, 2024*

So, my beautiful tuxedo cat, Lucy, now has a a new Litter Robot, her second - living her best life, clearly. Bought these carbon filters that fit perfectly and were a steal compared to the official ones. Sorry, Litter Robot folks, you guys are great, but I'm not breaking the bank for essentially the same filters for far costlier. Lucy doesn't care as long as her bathroom is fresh, and these filters do the trick. These filters got your back (or, uh, your cat's backside). Trust me, they're the carbon heroes you and your feline friend deserves.
