Comsmart Pet Fountain Filter Set, 3 Triple Filtration System Replacement Cat Water Fountain Filters for Round 81oz/2.4L Automatic Pet Fountain Cat Water Fountain (Pack of 8)

These are great little filters for the Comsmart pet water fountain and I appreciate being able to easily order them from Amazon. However, even though the directions on the box indicate to change every 30 days, I find changing them every few weeks is more appropriate. If you look at them closely (on the bottom) you’ll see algae and mold growth will start to grow inside the filter. This isn’t a fault of the manufacturer it’s just a hazard that comes with a filtration device that is in contact with bacteria from pet saliva, room temperatures and recycled water. It fits the fountain perfectly, it is pretty durable given the conditions it’s in and it works great to filter the water. This does not replace the need for clean drinking water for pets. This is something to use in addition to that with many of the pet fountains on Amazon. This one specifically fits the Comsmart fountain, but I’m sure there are others it may also work with - your fountain will come with a filter and indicate when to change it and which will work to replace it.

I recently purchased the Comsmart Water Fountain Filter, and I couldn't be happier with it! This filter has been a great find at a great price for me. The water fountain ensures a constant flow of fresh, filtered water, which encourages my pet to stay hydrated throughout the day. The filter does an excellent job of removing impurities and odors, leaving the water clean and pure. It's incredibly easy to install and clean, making maintenance a breeze. It's a perfect fit for my 84oz/2.5L capacity water fountain. Overall, the Comsmart Water Fountain Filter is a fantastic investment for any such water fountain owner who wants to promote their pet's health and well-being. I highly recommend it!

The whole water bubbler with filters is great. It has a built in light. But this review should only be about the filters as that’s the picture being shown. Plus I did a review of the full product before. These are much better filters and worth the cost. I have gotten cheaper versions and my dogs seem to be able to tell the difference. I also can see the difference in the capturing of the food crumbs, dirt, and other things that my dogs might get on their chins and mouths -then they drink the water and it lands in the water bowls. I also highly highly recommend using a filtering water system if you have a white dog. White dogs get an orange color around their muzzles and any place they might lick on their bodies. If they drink filtered water this doesn’t happen. If your current white dog has any orange on them from licking, infection, or whatever-switch to a filtered watering system, or bottled water. Wait for the hair that’s discolored to grow out and once it does you will have a gleaming white dog better then ANY whitening products on the market. Better then Angle Eyes or others and thus is 100% safe for your pet. I promise if you try this method for a Westie, a Poodle, or any other dog or cat-it works. If you switch back to unfiltered water, then your pet will just go back to having orange around mouth, ears and any place else they lick.

Compared to the filters I bought for about the same price a year or so ago, these have at most half as much resin. It remains to be seen how well they keep the fountain water fresh. I will update this review after the first one has been in use for a few weeks. Update: after 4 weeks of use, the first filter is performing satisfactorily. The fountain water doesn't get slimy even if I don't put in fresh for a couple days (unlike some similar filters I had purchased elsewhere in the past). 4 Stars.

Works great for our cat fountain

I have the isYoung cat water filter and these fit perfectly. Work great at keeping the water good.

Since I want my cat to have a clean source of water, maintaining a cat water fountain is necessary as well as will be a regular purchase. So I want filters that are effective cleaning the water as well as economical. These fit my bill. I have read other reviews about filters in general that have become moldy, etc. So far these filters have been excellent. I regularly wash the fountain each week and replace the filter every two weeks. I also check the fountain everyday for water volume as well as cleanliness. Did any dirt or small bugs get into the fountain? I will update this review in a few weeks. We are getting into the heart of the summer heat. (Winter is coming)

Works fine just a little bit big, wish there was more granules for the money.

Perfect

use then in cat drinking fountain i change 1 every4-6 mths and the cats love the fresh water

.

The product was only a tiny bigger than my fountain but good enough, just stuff it in, somehow it'll work lol

Don’t waste your money. I’m now going to have to buy catit after buying this waste of money product.
