These replacement filters are by far the best ones I’ve tried for my 3.2L/108oz cat water fountain. They fit perfectly and do a great job keeping the water clear and fresh for my cats. The combination of the main filter and the pre-filter sponges helps trap hair, debris, and other particles so the pump doesn’t get clogged and the water stays clean longer. One important tip—make sure you presoak the filters before using them. This helps the charcoal activate properly and prevents the filter from floating when you first put it in. Once installed, the water runs smoothly and the fountain is much quieter. I also like that the pack comes with both filters and sponges, so you’re fully stocked for multiple changes. It’s a great value for the quality and peace of mind knowing my cats are drinking cleaner water. Highly recommended for pet owners. Read more

We have purchased these several times to replace the filters in our cats’ water fountain. Cats are often drawn to water drinking fountains because the flowing water is more appealing to them than stagnant water in a bowl. The movement and aeration can make the water taste fresher and stimulate their natural instinct to drink from moving sources, which in the wild would be safer. Changing the filters frequently is crucial for several reasons. Firstly, filters remove impurities, hair, and debris, ensuring the water remains clean and palatable. The constant circulation also keeps the water oxygenated and tasting better, which can entice even picky drinkers. Secondly, a clogged or old filter can become a breeding ground for bacteria and mold, contaminating the water and potentially making your cat sick with issues such as UTIs. Regular filter changes ensure your cat always has access to fresh, clean water, which is vital for their hydration and overall health. Don’t forget than when changing out the filters, you should also wash all surfaces of the interior of the fountain with hot soapy water to remove any potential biofilm. Read more

Bought this pack of filters for our animals water bowl. Each filter lasts about 2-3 weeks, they filter out all the nasty particles floating in the water and were cheap! They fit perfect and function just as well as the name brand ones, for a quarter of the price. Just make sure to let them soak for 10-15 min in water before installing for best performance Read more
