Price

I love the fountain these fit. They are reasonably priced and last longer than other filters making them very cost effective.

The black ring filter discharged small black pieces of material into the water, negating the purpose of the filter. Please avoid this inferior product. The water filter is the most important part of the water fountain, maintaining the clarity of the water and the health of the pet. These filters pose a hazard to the pet. Deserves a zero....

I like the idea of a free standing base to recharge. I did not like the plastic water holder. I thought I ordered one with the steel container. At least what the picture showed. The water container had to be rinsed every other day because a white film would appear on the sides. Not using it anymore.

Get a year’s supply when you order the Petlibro fountain

Got a year’s supply when we ordered the fountain. You’ll want to do the same as both the filter and pump “ring” need to be changed monthly.

The prefilters drew my attention to this item. I needed the filters & the sponge that wraps around the filter had broken so when I saw this I had to get it. Both items fit perfectly & the price was way better than just getting a package of filters. I will definitely repurchase.

ok

Decent apparently quality for the filter packs; poor quality on the round foam prefilters. They are not cut straight and are not wide enough as a result.

Helpful item for our pups

We have three dogs and they are drinking clean, clear water like crazy! They love it and so do I! Clean it once a week, fill it with a pitcher of water when needed
