## Product: Litter-Robot 4 Carbon Filters
**Brand:** Whisker

If you're using the Litter-Robot 4 by Whisker, managing those litter box odors is pretty important. One way to do that is by regularly changing the carbon filters. According to the manufacturer's product description, these filters are designed to help keep any bad smells at bay.

Our research shows that many people notice a big difference in odor control when they keep up with replacing these filters. One person even said that despite having a bunch of cats, using these filters really helped with the smell.

As for how often to change them, the manufacturer suggests replacing the carbon filter about once a month to keep things working their best. But if your litter box is getting heavy usage, you might find you need to change them more often—or less.

Some folks have mentioned getting creative and cutting the filters in half to extend their use, which seems to work for them. Swapping out the filters is simple and doesn't need any tools, which is convenient. 

You can also use the [Whisker app](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dwhisker%2Bapp%26tag%3Dssw.ans.tx-1-20) to help align everything during a filter change.

Most people seem pretty happy with the filter quality, noting they're similar to the ones from the official website but without the extra delivery fees. Though someone did mention they felt these filters were a bit thinner than the original ones that came with their Litter-Robot, they still do a solid job at controlling odors.

So, keeping an eye on those filters and changing them regularly is key to keeping your space smelling fresh. It might seem like a small task, but it can really make a difference, especially if you've got multiple cats around.
