Cheaper Option That Works Better Than Petlibro’s Own Filters
Incredible product and an incredible value when compared to Petlibro’s own filters. Not only are they comparable in quality, but they are far cheaper *and* they ironically fit the filter housing much better than the ones made by Petlibro. When I use to buy genuine replacements from Petlibro, it drove me up the wall that a portion of the filter did not sit correctly in the housing…not an issue with these!

Great product and a fair price
Changing the filters is so important for keeping the water in the Cat Water Fountain in optimum working order. Purchasing in bulk saves money. This product checks all the boxes.

Very Helpful and Convenient for Pet Water Fountain PETLIBRO
These replacement filters have been really helpful for my small dogs. Since using them, I don’t need to change the water as often like I used to before. The filters do a good job of keeping the water clean and fresh.They fit the PETLIBRO water fountain well and are easy to replace. Having a 20-pack is also convenient and lasts a long time. Overall, these filters make maintaining the fountain much easier and are a good value.

Perfect off-brand option
They fit perfect, last long enough between cleanings (i do 3 weeks). Definitely don’t buy the name brand ones. These are way more cost effective

Great value.
I’ve been very happy to save money with these filters. Initially I was getting an error message but resolved by soaking the filters a bit longer before inserting. Since I made this change I have no problems. Glad to not have to worry about fresh water daily for my kitty.

Better Than OEM Filters – My Cat Approved
I’ve been using these SORON replacement filters for my cat’s water fountain for about two months now, and I’m honestly kicking myself for not switching sooner. After spending way too much money on the manufacturer’s overpriced filters, these have been a game-changer.The quality is noticeably better than what came with my fountain. The water stays cleaner longer, and I swear my cat drinks more water now which was the whole point of getting the fountain in the first place. The filtration seems more effective because the water doesn’t get that slightly stale smell as quickly as it did with the original filters.My favorite thing about these each pack literally has everything you need for a complete filter change. No more hunting around for different parts or realizing you’re missing something halfway through cleaning the fountain. It’s all there: the main filter, foam pieces, whatever else needs replacing. Makes the whole maintenance routine so muchMy wallet is definitely happier, and so is my cat (she’s very particular about her
