Works great
It fits the litter robot and is cheaper than the manufacturer’s. Works like it’s supposed to considering it’s just a carbon filter.

Great fit
I grit this to go with my whisker robot litter 4. Fits perfectly. Keeps smell down. Reminds me to do a good box cleaning. Best litterbox I have ever purchased and these are great to help it run smoothly

Thick replacements compared to original product
These replacement filters fit my Littter Robot 4, but they are much thicker than the originals. Keeping that in mind, I haven't had any issues with them popping out from under the frame, nor causing any issues. I do replace the filter in 2 robots every month, a 12 pack will last me 6 months. Yes - these filters make a big difference in smell and dust so do change them monthly!!

Great buy for the price
These fit my LR4 perfectly, however I don’t feel like they last as long as the OEM version so you have to replace them more frequently.

Worth the price!
I was skeptical in buying these because of the mixed reviews but so far I have not had any issues. At first, I thought it was not helping with the smell but after a day, I noticed that the smell was gone and that it actually was working. The filters are not thick but they do the job, which is why I must say they will need to be replaced more often than the originals. They were easy to install and the size was perfect for our litter robot 4. I would say the quality is obviously not like the original brands but you’re getting a pack of 8, so I’d say it’s worth it.

Works as intended
Fits the litter robot perfectly, and much cheaper than the official product. I think it definitely reduces odors.

Affordable and Effective Carbon Filters
The QUEARN 8 Pack Carbon Filters are a great, budget-friendly alternative to the more expensive litter robot filters. They fit well and do an excellent job absorbing odors from the cat litter box. If you want quality odor control without breaking the bank, these are a solid choice!

Thin, but using 2 works fine.
Significantly thinner than the brand version, so not a direct replacement. I used two at once, which works well, and probably still cheaper overall.
