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

These work fine for the LR
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

Works for my litter robot!
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.

Works
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.

Best investment ever
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.

Works as expected
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.

These work just as well as the litter robot filters but they are both to expensive for what they are imo.These were still cheaper than the name brand though and seem to do the same job.

They are not very good filters. They do not block odours at all, in my litter robot.

I went to change my filter for the first time after buying this as a set offered by Amazon. It does not match the slot. Litter robot for takes a crescent shape filter not a rectangular one.
Client d’Amazon –
These are not compatible what a lie!!!!
