ONECUTE Cat Fountain Replacement Filters, 10-Pack 3.0 with Four-Layer Filtration

ONECUTE Upgraded Filter Units 3.0 are replacement filters for compatible Eversweet cat water fountains, with a four-layer filtration system and an approximately 5.5-inch (13.97 cm) outer diameter.

• Compatible with Eversweet 2S, 3, 3 Pro, Solo 2, Solo SE and PURE DRINK fountains — choose a filter for these fountain models.
• Ten filters per pack — keep replacements ready for routine fountain maintenance.
• Replace every 2 weeks in summer and every 4 weeks in winter — follow a seasonal schedule for regular filter changes.
• Soak for 10 minutes and rinse before use — help prevent activated carbon dust from entering the water.
• Reset the fountain after changing the filter — keep the device’s filter tracking up to date.

These round replacement filters are made for cat owners who want to maintain a compatible Eversweet fountain and filter its drinking water. Their layered construction addresses hair, food particles, chlorine, odors and heavy metals, while the ion exchange resin also helps improve water taste. The filter is designed for the listed fountain models rather than as a universal replacement.

Which Eversweet fountains are compatible?

ONECUTE Upgraded Filter Units 3.0 fit Eversweet 2S, 3, 3 Pro, Solo 2, Solo SE and PURE DRINK pet water fountains. Match your fountain to one of these models to choose a compatible replacement. Each pack contains 10 round filters for planned changes over time.

• The filters are replacement units for the compatible fountain models named above.
• The pack contains 10 filters.

How does the four-layer filter work?

The filter combines four layers to address different kinds of material in fountain water. High-density cotton non-woven fabric catches hair and food, while activated carbon particles remove chlorine and odors. Ion exchange resin filters heavy metals and improves taste; an ABS grid helps keep hair and larger particles from entering the fountain.

• Filtration materials: cotton non-woven fabric, activated carbon particles and ion exchange resin.
• The ABS grid blocks hair and larger particles from entering.

What size is each round replacement filter?

Each ONECUTE cat fountain filter measures about 5.5 inches (13.97 cm) across, with a hollow center about 1 inch (2.54 cm) in diameter and a thickness of about 0.4 inches (1.02 cm). Compare these measurements with the filter position in your compatible fountain when selecting a replacement.

• Shape: round, with a hollow center.
• Approximate thickness: 0.4 inches (1.02 cm).

How often should I replace and prepare the filter?

ONECUTE recommends changing the filter every 2 weeks in summer and every 4 weeks in winter. Replace it more often when multiple cats use the same fountain; the actual timing depends on filter condition, and the indicator light flashes when a change is needed. After replacing a filter, reset the fountain device.

• Before installation, soak the filter in water for 10 minutes.
• Rinse thoroughly under running water before use.

These filters suit cat owners using one of the compatible Eversweet fountains who want a round replacement with multiple filtration layers and a clear maintenance routine. Their model-specific fit, four-layer construction and preparation steps make them a practical choice for maintaining the fountain’s water filtration.
