AONBOY Cat Fountain Filters, 16-Pack for S3-SC with Carbon & Sponge

AONBOY Cat Water Fountain Filters are replacement filters for the Stainless Steel Cat Water Fountain (108oz/3.2L S3-SC), with 8 carbon filters and 8 sponge filters for ongoing water filtration.

• Fits the 108oz/3.2L S3-SC Stainless Steel Cat Water Fountain — choose filters matched to your fountain model.
• 16 filters: 8 carbon and 8 sponge — gives you both filter types for replacement.
• Four-part filtration system — combines a sponge pre-filter with cotton, activated carbon and ion exchange resin.
• Soak and rinse for 5 minutes before use — prepares each filter before installation.
• Recommended replacement every 2 weeks — provides a clear filter-change interval.

These replacement filters are made for cat owners who use the compatible AONBOY stainless steel fountain and want to maintain its filtration routine. Cats need adequate hydration to support metabolism, and proper hydration can reduce the risk of urinary tract infections. The filters support the fountain’s water-filtration setup; they are not a substitute for providing your cat with access to drinking water.

What does the AONBOY filter system remove or change?

The AONBOY Cat Water Fountain Filters use a sponge pre-filter and a deeper filter made with cotton, activated carbon and ion exchange resin. The sponge catches larger impurities, including hair and food particles, before water passes through the deeper filter. The other materials work to reduce odors and soften the water.

• The sponge targets visible, larger debris such as hair and food particles.
• Activated carbon and ion exchange resin are part of the deeper filtration stage.

Which cat fountain do these replacement filters fit?

These AONBOY Cat Water Fountain Filters are compatible with the Stainless Steel Cat Water Fountain (108oz/3.2L S3-SC). Match the model name to your fountain before choosing this filter set, since compatibility is specified for that fountain model.
