DIANU 9-Pack Replacement Filters & Pre-Filter Sponges for 3.2L Stainless Steel Cat Fountain

Designed for your DIANU fountain family

Keep your pet’s fountain running smoothly with a 9-pack of replacement carbon filters and pre-filter sponges crafted for the DIANU stainless steel cat fountain (3.2L/108oz). This official set provides ready replacements to help maintain a clear, inviting water supply between refills.

Multi-stage filtration for fresher water

The filtration system blends activated carbon with ion-exchange resin and a pre-filter sponge. Activated carbon helps reduce odors and can enhance the perceived taste, while the resin can soften water. The sponge layer captures hair, dirt, and food particles before water reaches your pet’s bowl, contributing to a cleaner drinking experience.

• Activated carbon targets odors and improves palatability
• Ion-exchange resin softens water and supports clearer drinking water
• Pre-filter sponge traps hair and debris for a cleaner fountain

Simple care for ongoing freshness

To keep performance steady, replace the filter and sponge regularly. Replacement frequency depends on how often your pet drinks and how many pets use the fountain. A practical guideline is every 1-2 weeks.

• Soak the filter in clean water for 5 minutes
• Rinse for about 30 seconds before use
• Check the sponge for clogs and replace when needed
