32 PCS Cat Water Fountain Filter Replacement (16 carbon filters + 16 foam sponges) for 108oz/3.2L and 67oz/2L fountains

If you run a cat water fountain, filters are one of those “small” parts that make a noticeable difference. This 32 PCS replacement pack is built for regular upkeep, with 16 carbon filters and 16 foam sponges, so you’re not constantly hunting for the right replacement.

The listing frames these filters as compatible with several fountain models and sizes (108oz/3.2L stainless steel and 67oz/2L). On paper, the goal is straightforward: cleaner water taste, less build-up from hair and food residue, and reduced odours—while keeping the system cycling through a three-layer style filter approach.

The essentials

This is a replacement filter pack for cat drinking fountains, supplied as separate sealed units in the box. It combines two filter types in equal quantity: activated carbon filters and foam sponges. That matters because fountains typically need both mechanical trapping (foam) and water conditioning/odour support (carbon).

It’s also designed around a repeating routine. The guidance provided is to rinse before first use (3–5 minutes under running water) and then switch filters frequently enough to maintain freshness.

What it’s designed to filter

The filter system is described as working through a three-layer cycle approach and including activated carbon. The stated targets are hair, food residue, odours, and softer-feeling water.

In practical terms, you can think of it like this: if your cat sheds, or you’re using the fountain in a busy household where food bits inevitably find their way into the water, you’re more likely to see the benefits of having carbon and foam replacements ready on a schedule.

That doesn’t mean it will fix every fountain issue—if there’s poor cleaning habits, unusual mould build-up, or the fountain isn’t assembled correctly, filters can only do so much. But for routine maintenance, it fits the job.

Where it makes sense (and where it might fall short)

It’s a solid value-style purchase if you want a longer run of replacements rather than buying individual filters each time. With 32 pieces total (16 + 16), it suits owners who already run their cat fountain regularly and want to stay ahead of odour and residue.

However, you should be careful about compatibility. The listing says high compatibility with “6 different models” including Wopeet, Bento and Illike, but it doesn’t list those models in full here. If your fountain isn’t one of the mentioned ones—or if your fountain size doesn’t match 108oz/3.2L or 67oz/2L—this may not fit as intended.

Also, filtration performance depends heavily on how often you replace the filters. The recommended change interval is every 2–4 weeks depending on the number of cats. If you regularly push replacements far beyond that window, you may find the “fresh water” effect fades.

Replacement routine: simple but important

The instructions are clear about two stages: rinse and replace.

Before using the filters, the guidance is to rinse thoroughly under running water for 3–5 minutes. After that, fit them into your fountain.

Then, plan on changing filters every 2–4 weeks depending on cat count. That’s fairly typical for pet fountains, but it’s worth treating as part of the product’s value—because the pack only helps if you actually use it.

Materials and pet safety angle

The foam and carbon components are described as made of BPA-free materials. That’s the main safety detail provided, and it’s worth checking against your own preferences when you’re choosing replacement filters.

Mini FAQ

How often should I change the filter?

The guidance provided is to replace the cat fountain filter every 2–4 weeks, depending on how many cats use the fountain.

Do I need to rinse the filters before putting them in?

Yes. The listing recommends rinsing under running water for 3–5 minutes before using.

What are the filters for?

They’re described as helping filter animal hair and food residue, absorb odours, and support softer water for fresher drinking.

Is it compatible with all cat water fountains?

It claims compatibility with multiple models and the specified 108oz/3.2L and 67oz/2L stainless steel fountain sizes. If your fountain model or size isn’t included, you may want to double-check before buying.

Does the pack include both carbon and foam filters?

Yes. The package includes 16 carbon filters and 16 sponge (foam) filters.

Should you buy it?

Buy it if you already use a compatible cat drinking fountain in the stated sizes and you want a replacement pack that supports regular maintenance (with carbon plus foam), ideally keeping to the 2–4 week change routine.

Skip it if your fountain model isn’t one of the listed compatible types, if your fountain size doesn’t match 108oz/3.2L or 67oz/2L, or if you’re unlikely to keep up with filter changes—filters can help, but they can’t compensate for long gaps in cleaning and replacement.
