MEWTOGO 6 Pcs Carbon Filters for Cat Litter Box Robot 4 - Thickened and Durable Replacement Filters to Absorb Unpleasant Odors Control Damp from Pets and Keep Home Fresh

So I waited a little too long to realize that the Liter Robot has a filter and that it needs to be changed every month or so. I’ve had mine for 2.5 years and never changed it! Sounds gross I know, but honestly it never smelled! So I ordered these to save a little money and honestly they seem to be the exact same thing that was provided from LR originally. They work great, same thickness and easy to install. Very pleased that you get many filters for such a great price too!

Perfect fit for the litter robot. Works great

So far so good, fits the Litter Robot 3 connect. seems thicker than the ones that came with my robot originally. At first I thought they were a bit toooooooo thick to fit under the prongs, but I got it attached just fine.

Fits perfectly does a good job at odor control. Better price than original filters. High quality, thick filter. Easy to change

This trio of MEWTOGO carbon filters fits the Litter‑Robot 4 perfectly. Crafted from activated fiber carbon, they neutralize damp and litter smells quickly and effectively. The filters are non-toxic and safe for pets. With simple drop-in replacement, it maintains freshness with minimal effort. I have never smelled a thing from this box and I have a sensitive nose.

There is a little wedge on the LitterRobot3 where the filter is supposed to fit into, it's a little large for that but I trimmed it and it works fine to help combat the litter odor.

I have two litter robots and they stunk up my basement. I never replaced the filters, and when I found out the robot had them, I ordered these. WHAT A DIFFERENCE! I can be within 10 ft of the robots and cannot smell pee or poop. So yes, these work amazing and are 100% worth changing once a month.

Compared to the original litter box ones, I feel like the ones I received in my order are worse at neutralizing odors but they still kinda work
