The Best Cat Water Fountain Filters
Many of us turn to water fountains to keep our pets happy and healthy. They produce a steady flow of refreshing, filtered water. But, over time, the filter within your cat's fountain will get dirty and full of debris. That's when it's time to change it. And to help you do that, we've done some digging to bring you high-quality options for the most popular models.
What to Look For
Your cat’s water fountain keeps them hydrated while helping you avoid the expensive vet bills associated with urinary issues, which is a common problem for felines. However, to keep that fountain running smoothly, you’ll need to change the filter regularly. By choosing a properly fitting filter with high-quality materials, you can keep your pet healthier and your fountain running at its best. Take the PetSafe Drinkwell filters, for example. They fit a wide variety of fountains and clear your tap water thoroughly. But if you need a rounded option, consider the Catit Triple Action filters. Check out the list below for more details on these and the rest of our top picks.
Catit Triple Action Fountain Filters

These filters from Noodoky can help. Four thick layers of carbon, ion exchange, and cotton fibers remove impurities and additives that can lead to those odors for better hydration.

PetSafe Drinkwell Replacement Filters
Completely clean
Many round filters allow microscopic sediment to pass through to the water, making it taste funny to your furry overlords. That won’t be a problem if you use these Drinkwell replacement filters from PetSafe. Each one is separated into six sections, and they boast twice the carbon of the average filters. As a bonus, they fit a variety of fountains, so your options aren’t too limited.

NPET Pet Fountain Filters

Like the NPET models, some cat fountains use smaller filters than most. That’s when we recommend the NPET fountain filters. High-density materials remove pet hair, minerals, and other contaminants to keep your pet’s water smelling and tasting fresher than ever. Best of all, you only need to replace them every two to three weeks.
Pros:
- Changing the filters is pretty effortless; it should only take a few seconds.
- Many cats who’d refuse water using other filters will drink water that filters through these.

Cons:
- You may need to change this filter more often if you have multiple cats.
Frequently Asked Questions
Why should I get my cat a fountain?
Cats, in general, don’t like standing water. There are several theories as to why, but most experts agree that they instinctively know that standing water often holds more contaminants. Plus, they have a powerful sense of smell, allowing them to know if there’s anything dangerous in it.
What does carbon do, and why do most filters have them?
Carbon absorbs impurities and contaminants that can cause bad tastes and odors in drinking water. It’s often in water filters for refrigerators, taps, pitchers, and pet fountains. Your cat is more likely to stay safely hydrated by removing those odors and tastes.
