Kastty 8 Pack Replacement Filters and Pump Filters for Battery Operated Cat Water Fountain, Made of Activated Carbon and PP Cotton, Food Grade

Perfect fit. For some reason replacement filters were difficult to find

Awesome product! Before I bought this, I asked my vet if it's worth it and as it turns out, vets recommend these type of devices as it tends to make cats drink more water. She couldn't really explain why, but I found with some research, it mostly has to do with their whiskers not being constricted by a "bowl". I bought, charged, added filters like instructed and I can honestly say, my cats drink more water now then I ever saw them drink before. I charge it every Sunday for the full day while cleaning/doing laundry & it will last till the next Sunday with no issues. The fact that it has different settings is also great. I keep on the setting that turns it on when they approach and turns off after a few minutes. It has a good range, so turns on a lot by us just walking around kitchen, but again, turns off within 2 minutes so not a big deal. One of my cats is all black and some people stated that these devices don't "see" them. This one has no issues there either. It's truly great!

Easy and intuitive to assemble, I like that it charges with a standard Type C USB charger. Much better than having another propriety charger lying around.My only issue is the long distance that the IR sensor activates from. My kitchen is 10ft deep and the unit will activate if I barely step into the room. This doesn't present a problem necessarily, except it affect battery longevity. I expected to only have a 1-2ft range and only activate as an animal the height of a cat approached it, versus a 6ft human from 10ft away.Otherwise, easy to replace the filter, easy to operate and hopefully it continues to operate well. Time will tell.

I have several water fountains similar to this one in my house. I needed a larger one for my two frenchies. This is great, my dogs and cats love it. The only thing that would make this perfect, would be if it was cordless. I gave four stars only because it was not cordless.

My cats love it

The big filter is just fine easy to replace. But the smaller white sponge when you order new ones you get a different style. I changed my filters using these filters and I could not get the change filter light to go off. Talking through Amazon I was able to get another fountain in 2 days. Now we will see how it goes. Let me say I do love this fountain I was able to go away for 4 days and my cat had the water to drink that he needed. I love how easy it is to take apart and wash the parts you need to wash. But on their video's it shows your suppose to check to see if the light comes on. BUT there is no button on this motor to check the light. So we will see how it goes.

They fit the water tower perfectly! Will keep buying them. Thank you

Easy to use in pet water fountain. Last quite awhile. Great filters!
