Pet Fountain Filters, Carbon Replacement Filter for Cat and Dog Water Fountain-4 Packs

Cant tell if does much but i keep buying them

Awesome price for 8 pack

They seem to get dirty quicker than I had thought they would. For the price, however, go with an 8 pack or more.

Its a filter, it filters. It does its job which I am thankful for.

Makes clean water easy.

The filters are very easy to install, just pay attention to directions for which side faces up!

Great product I recommend it

My cat now drinks more water, change the filter once a month and dont have to worrie about a thing.

Compatible with multiple water fountains. Easy to change and food filter

I bought this because it is cheaper than the venken one, but this leaves a weird yellow residue on the fountain. I clean my fountain 1x a week and its always hard to clean because of it.
