Questions & Answers

8 Customer Questions

What size are these?
Answer by ChewySep 24, 2022
These replacement filters measure 2.1 inches x 2.1 inches and fit all Petmate Replendish or Mason style waterers regardless of the gallon size.

Do you take off what looks like a little plastic cover on filter first?
Answer by ChewyFeb 28, 2021
Thoroughly rinse out filter with running water before inserting in to the fountain. Although completely harmless, doing this will cleanse the filter of any charcoal dust that may have become loose. After rinsing, insert the filter in your pet fountain and secure it with the black strap provided. It is recommended the filter be replaced every 2 to 4 weeks and more frequently if multiple pets are using the fountain.

Will this Prevent algae growth in pet water?
Answer by ChewyOct 06, 2021
The filters remove toxins, particles, bad taste and odor. It is recommended the filter be replaced every 2 to 4 weeks and more frequently if multiple pets are using the fountain. To help prevent any algae growth it is recommended to clean your cat fountain effectively once a week and change the water at least once every other day.

Will these work with the stainless steel replendish waterer?
Answer by ChewyMar 04, 2023
The filters are compatible with the PetMate Replendish and Petmate Mason.

Works great

Much needed, especially with multiple cats drinking from one fountain.

These are useless

I bought two packages of these, and even after thoroughly rinsing them, they turn the water bowl brown in a day. They are useless, and I ended up throwing them away and going elsewhere to but a better quality product. This is likely to be my last purchase through

If they're ever in stock again

I've been using these water filters in my waterers for a few years now, ever since I got my cats. And my snobby kitties that love cold sink water prefers water out of the waterer when I have a new filter on standby! Please restock so I can buy more!

Fresh Water = Happy Cat

So glad to have found these charcoal filters for my cat's water dispenser, and in bulk as well! I change it on a monthly basis and am happy that my cat will be set for the year with this order. She loves her water, and she is very happy to have fresh water as well!

Good Price

Good price and delivered very next day. Would highly recommend to anyone who has the automatic water feeder. This gives several months supply and you don't have to keep buying them every 30 days.

Wrong Size!

I ordered these filters because it was listed as the recommended filters alongside the dog waterer that I purchased. Imagine my unpleasant surprise when it turns out that the filter was way too small!

They're filters

These filters are good replacements for the Petmate self-refilling water bowl. They were reasonably priced and arrived quickly.
