Great quality and excellent price. I was tired of spending $10 or $15 every few months for new filters. These have been working very well so far. They are slightly smaller than the original, but as long as you have them in your canister it's not a problem. This is one expensive cat litter, but it really does do a great job. Highly recommend. Be sure to replace it once the bag gets full though. If not, there will be litter dust everywhere. My box still looks brand new.
Good Review
