Is it compatible with the LitterHopper attached?

The LitterHopper does not interfere with the carbon filters. The carbon filters go on the outside of the globe and is covered by the bonnet. The LitterHopper attaches to the back of the robot.

How often do these need to be changed?

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.

Good value

Works as expected - we love our litter robot. Seems expensive at first but one filter should last a month, so a pack of these is a 6 month supply
