Great substitute
I bought these to replace the initial filter that came with my litter robot 4. Upon comparison to the original, these actually feel a little more dense, but overall they’re extremely similar at a lower price point. They fit right into the slot perfectly too.

Glad these exist
They work well and fit perfectly. We noticed the difference right away and haven’t had to change it yet. We are happy with our purchase, thank you!

Filters are much thinner than advertised. 1/4″ not 1/2″
I ordered a 12 pack of these filters for my litter robot 4.They shipped OK and they arrived OK with no damage. I was excited to get these because being 1/2″ is basically what the actual litter robot Whisker brand filters are and there’s a lot of filters on the market that are much thinner.To my disappointment, when I got these filters they were closer to a 1/4″, half the size of what was advertised.I contacted the seller and the seller said that they were that way because they were compressed in the packaging. I left the filters out for 2 days to see if they would expand, they did not expand. They all stayed right about a 1/4″ thick.Not happy with these.If you do, in fact, buy these filters, when you get them, please measure them to see if they are truly what is advertised as .5″ (1/2″)I’ll be surprised if the ones you order are as advertised.look at the picture of the filter I received Again, you’ll see that it’s not 1/2″, and a picture of the item description showing .5″

Smaller and thinner than original filter
These filters are smaller and thinner than the original one. It doesn’t look that they will work good enough because they don’t cover the whole area they are supposed to cover.
