These filters fit my LR4 perfectly. They are every bit as good as the expensive name brand. I will definitely buy again.

These seem to be slightly thicker than the LR4 brand, but they fit fine. Seem to work the same (honestly I'm not sure these do much, but I always change them as instructed anyway). These work at least as well as the original though.

These fit perfectly and even feel a bit thicker than the original filters. Hard to say how effective they’ll be until the odor begins, but for now they seem like an excellent replacement. They feel spongy and durable, so I’d imagine they will hold up to light rinsing every once in a while also. Good replacement option.

The filter is very similar in length and shape to the original name brand filter. I have an LR4, filter is a bit thicker than the original brand. I just replaced my filter and not seeing that it makes a difference using this brand. So far so good.

At first I thought they were a bit too small in the shape, but then looking back at the originals, they are the same way. It's not like the filter on an air purifier where you need it to entirely cover the opening, so it doesn't matter either way. Also, these are thicker, almost twice as thick. As far as I know this type of charcoal filter is all the same, so thicker is just better. I was amazed at how dirty the original one was after just a few months, and now I realize that you should change these every month. Being way cheaper than the original ones, I will be getting more of these when I run out. 5/5

Fits perfectly in my LR4. I didn't realize until deep cleaning that this filter existed, and it was nasty by the time I found it. Glad to have a nice replacement option for a way better value than ordering from LR.

I previously bought replacement filters on Amazon from a company called QEARN or something like that. Texture, color, etc is similar, but these are much thicker than the other off brand option - see pics.It does seem to reduce smell, but I can’t speak to how the smell reduction compares to the original filters bought from the Litter Robot company (because I’ve never been willing to pay the brand-name prices haha). That said. I would definitely buy from this company again over the other knockoff option since the thickness is so much better.
