Fresh Headquarters 6Pack Activated Carbon Filters – Compatible with Litter Robot 3 Cat Litter Box – Eliminates Odors & Installs Easily - Made in USA

Def not as thick as the original but they at least fit in the litter robot 3 so…

These seem to work as well as the original and are about half the price. I also found that using a 13 gal trash bag works just as well as buying the bags designed for the LR. I have five cats and empty the LR every other day

Fits perfect for my litter robot and seems to be doing the job for the smell. No complaints and have had it in for over a week now.

My old filter was not keeping any smell at bay, these fit perfect in my litter robot and has lasted a few weeks on 1. I assume I’ll have to switch out 2-3 times a year for a 1 cat household.

These really saved me with my Litter Robot 4. I was very upset I made such a big purchase, and the previous filters were not working. But these saved the day. Would highly recommend it.

I ordered these as a replacement for the filter in my Litter Robot. It was really easy to install and I immedicately noticed the control of odor. I am really glad that these came in a three pack, that will last me 6 months to a year, depending on how often I feel the need to replace them. I would definitely order these again.

Reviewed the wrong product previously. Hoping I can get back the review!!! These were fine.

Had to return them.Opened it and it shed everywhere
