UMOCUOY S17-12PCS Cat Fountain Filters, Carbon and Sponge, 12 Each

Some cat owners want replacement filters that match a specific fountain, others need a simple way to keep up with routine filter changes. The UMOCUOY S17-12PCS set is designed for compatible stainless steel cat fountains in the listed capacities.

It pairs carbon filters with separate sponge filters, giving you both parts needed for a regular replacement.

Is your fountain one of the compatible models? Check the fit before choosing a refill so the filters are matched to your setup.

Strengths

The carbon filter combines activated carbon and ion exchange resin, while the sponge layer helps catch hair and fine debris. Together, these materials support filtration and water purification, with the stated aim of improving water taste. For a cat fountain used indoors, that makes this set a practical way to refresh the filtration without replacing the dispenser.

The pack contains 12 carbon filters and 12 sponge filters. Each piece is individually sealed, helping keep replacement parts protected until you are ready to use them. Buyers often highlight ease of use, filtration, and fit, feedback on filter size is mixed, so matching the refill to the fountain is an important part of choosing the right set.

The essentials

These replacement filters are listed for UMOCUOY, GIOTOHUN, HOOISE, ATMZIQXR, and IHOUONE stainless steel cat fountains with 74 oz, 88 oz, or 108 oz capacities. The product details also identify a 2.6-liter fountain match. Before ordering, compare your fountain’s brand and capacity with those compatibility details to select the appropriate refill.

The set includes 12 carbon filters and 12 sponge filters. Rather than replacing a working fountain, this approach lets you refresh its filter components as part of regular upkeep. It is intended for cat water fountains, so the useful distinction is compatibility with the listed stainless steel models—not a universal fit for every dispenser.

How to take care of it

Before installation, soak a filter in water for 5 minutes to remove dust. The use guidance recommends changing the filter every 2–4 weeks to help keep fountain water clean. This gives you a straightforward routine: prepare a fresh filter before fitting it, then replace it on the recommended schedule. Keeping the refill set on hand can make those routine changes easier to plan.

When it makes sense

This set makes sense if you already use one of the listed compatible fountains and want carbon and sponge replacement components in one purchase. The two filter types serve different parts of the filtration process, while the individual packaging lets you open replacements as needed. For a household where a cat’s fountain is part of its everyday drinking setup, routine filter changes offer a simple way to maintain the fountain’s filtration without changing the dispenser itself. Confirming the model and capacity first helps you choose a refill that suits your existing fountain.
