These filters need to be changed once a month.

I've only used one, because they are a pain to install

I love my Litter Robot, but it's such a pain to open and install the filters that I've only used one out of this package that I bought months ago. I forgot I bought

I love my Litter Robot, but it's such a pain to open and install the filters that I've only used one out of this package that I bought months ago. I forgot I bought them! Litter Robot needs to rethink their filter system.

Fit perfectly

I had purchased my own carbon filters in the past and cut them to size. While cheaper, it was difficult to cut them to an exact size match (doesn’t cut smoothly)

I had purchased my own carbon filters in the past and cut them to size. While cheaper, it was difficult to cut them to an exact size match (doesn’t cut smoothly). These make it a lot easier. Just open the bonnet of the LitterRobot and swap the old one out with the new one. These also seem to be better quality than the carbon filter I previously bought and cut.

How small and thin

Keeps any smell away for a little over a month and I like that as it's in my BR
