Ordered the Penthouse Paws water fountain replacement for my cat’s water fountain. Monthly I change the filters and it’s extremely easy. My fur babies love their water fountain. I would definitely recommend picking up extra to anyone who uses the Penthouse Paws smart water system

These are amazing! I tried taking a picture of my cat drinking, but only got a dark picture of the fountain. The water is super clean and refreshing now! My cat used to not drink as much water and now she loves it. The water looks super clean and it does not stop the flow of water wither. Amazing add-on and needed for your kitty.

Great value! These automatic rechargeable pet water fountain are a game changer for me. The fountain recirculates the water, pushing it thru the filter. The filter catches loose pet hair and ensures they have clean drinking water. Awesome!

This is great because it comes in with 6 packs and also 6 of the foam you put in the dispenser and with a scrubber. Glad I purchased these because I was running low on my replacements. Keeps the water fountain fresh for the kitties.

These filters are great! I am impressed at how clean my dog's water is. It traps hair, dust any impurities in the water! There is six replacements and six carbon filters for the pump! The filters really are worth every penny for my pampered pooch!

The filters are necessary if you dont want your water fountain getting clogged with cat hair all the time and slowing the water flow down. This replacement back is decently priced and comes with 6 filters of each, plus an extra little scrub brush for the fountain tube for cleaning. It’s recommended to change every 2 weeks but with 4 cats I can get it to last for about 3.

Nice replacement filters for our cat's water fountain. We have a cat that is very picky as far as his drinking water is concerned. So, it is nice that we can have a fountain and the replacement filters to keep things tasting fresh for him. We haven't heard any kitty complaints so they must be doing their job! I recommend these!

They came exactly as purchased. They fit perfectly into the smart water water fountain. Of course you have to let it soak for 5 minutes before you insert into the water fountain. I suggest purchasing this product.

I have a water fountain for cats, yes I know the fountain is supposed to be for indoor use only but it is perfect for the feral cats that love a safe place to get a drink of clean water. Since I use my fountain outdoors, I need replacement filters to keep it clean. These fit perfectly and they came with the small sponge filters for the pump!

Box came slightly damaged, but the filters were OK. They kind of so their job, but it feels like the water can flow around it, so Im not sure how effective the filter is. It also comes with the smaller foam filters that go into the pump.
