6 Pack Charcoal Cat Litter Odor Filter for Litter Box Carbon Replacement Filters fits Hooded Litterbox and Catbox Pan, Gray

Use them in my litter box, to obviously get rid of the smell. I usually always just toss the litter box and just get a new one every six months or so because the smell, this time I thought I’d just give a new filter a try and it’s working! Like a brand new litter box there’s no lingering odors so far!

Just got these for my cat's litter box and boy are they great. They take the cat litter odor and dissolve it. That way if I forget to clean it my house smells fresh. Then you can't believe the odor that it blocked. GREAT JOB!!!

These have worked wonders for my cats' litter box! I have two cats and the litter box is in my bathroom and I barely smell it when I go in there and I CANNOT smell it anywhere else in my apartment.

Does its job

Doesn't control odor as well as litter robot filters

Keeps the litter box odor free.

Exactly as described.

It took a month for me to receive these because they were shipped to the wrong place the first time. The customer service was very friendly though and I was given a partial refund for the mistake.Now that I've finally got the filters I'm very pleased with the quality. They're thicker than the brand that came with the litter pan and they're working great for keeping smells contained. I have kittens who would constantly take the filters out to play with them but these are too thick for them to get out of the container.
