CatitDesign Senses Replacement Water Filtering Cartridge, 2-Pack (4-Pack)

These filters, OEM work as they should. They're a good value for their money, though the other brand work too. my cats enjoy drinking the water from their fountain, which is good enough for me. Easy to use and change out. Rinse off before placing in the fountain and you're good to go. Ours last us about three to four months before changing out, but we use filtered water in our fountains plus this on top. Highly recommend.

Seems to be filtering well. I clean the Catit Water Fountain weekly and change the filter monthly.

These are great. I tried some of the generic filters and was so disgusted with them that I will never stray from the name brand again. The generic filters let the water drain fast enough back into the container. They seem to filter okay but I lived in expectation of coming in and finding a huge puddle on the floor. Also, my cats didn't seem to like the slow draining water in their way either.

These filters are easy to use. I use mine twice and that is it. You get a little more bang for your buck that way.

Catit is an amazing water fountain for cats. My cat had not previously been interested in fountains of any sort before, but I decided to try Catit brand again since my previous cat was a big fan. My cat, Eli, took to it immediately without any coaxing. However, be aware of which filters to purchase for replacement. The ones without the white plastic part around the ring do not fit in the fountain. Although those filterless ones still work, they leave a ton of carbon at the bottom of the fountain, so for the newer Catit fountain, buy these ones.

I love the Catit water filter for my 8 cats. Realize that the motor will probably die in about a year and you'll have to buy a replacement through Amazon. It's not a problem to just disconnect the old pump and connect the new one. Also, don't forget to clean all the parts from time to time. Cat hair gets into the fountain as does residue from the charcoal filter. It's well worth the minimal effort for your babies.

You still have to change the water every five days, if not the cats quit drinking and go to the camode.

It's hard to say exactly how good these are without anything to compare them to, but I must say they are doing the job just fine. I change the water in the fountain weekly and add some water during the week. I left the filter in over a month since I lost track of time and honestly I use Brita water in the fountain anyway. The water has stayed clean and fresh.
