## Description

desertcart.com: QUEARN 8 Pack Carbon Filters Compatible with Model 4, Cat Litter Box Filters Replacement to Absorb Odors Control Damp from Pets and Keep Home Fresh : Pet Supplies

Review: 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
Review: 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.

### ⭐⭐⭐⭐⭐ Worth the price!

### ⭐⭐⭐⭐⭐ Thick replacements compared to original product
*by L***T on June 2, 2025*

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!!
