Comsmart Cat Water Fountain Filter, Pet Fountain Filter 3 Triple Filtration System Replacement Filter Pack of 8

Perfect

use then in cat drinking fountain i change 1 every4-6 mths and the cats love the fresh water

These are great little filters for the Comsmart pet water fountain and I appreciate being able to easily order them from Amazon. However, even though the directions on the box indicate to change every 30 days, I find changing them every few weeks is more appropriate. If you look at them closely (on the bottom) you’ll see algae and mold growth will start to grow inside the filter. This isn’t a fault of the manufacturer it’s just a hazard that comes with a filtration device that is in contact with bacteria from pet saliva, room temperatures and recycled water. It fits the fountain perfectly, it is pretty durable given the conditions it’s in and it works great to filter the water. This does not replace the need for clean drinking water for pets. This is something to use in addition to that with many of the pet fountains on Amazon. This one specifically fits the Comsmart fountain, but I’m sure there are others it may also work with - your fountain will come with a filter and indicate when to change it and which will work to replace it.

I recently purchased the Comsmart Water Fountain Filter, and I couldn't be happier with it! This filter has been a great find at a great price for me. The water fountain ensures a constant flow of fresh, filtered water, which encourages my pet to stay hydrated throughout the day. The filter does an excellent job of removing impurities and odors, leaving the water clean and pure. It's incredibly easy to install and clean, making maintenance a breeze. It's a perfect fit for my 84oz/2.5L capacity water fountain. Overall, the Comsmart Water Fountain Filter is a fantastic investment for any such water fountain owner who wants to promote their pet's health and well-being. I highly recommend it!
