Love these filters! Def noticed a difference.
Honestly, the price is what was holding me back on purchasing these but I am so glad that I finally got them. They are well-built, not an eyesore, great for those cats that urinate so high it seeps onto the floor, and super easy to clean. I bought the charcoal air filters and there is noticeable litter box odor. I also saw in some other reviews where people mentioned the liners eventually leaking so I purchased charcoal puppy pads and placed one underneath each liner just in case. My cats immediately took to using these boxes. I have one in my living room in a corner that nobody even notices that it is there. I definitely recommend trying this litter box.
