VANVE Cat Fountain Replacement Filters 32‑Piece (16 Filters + 16 Sponges) for 2L/2.8L/4L Fountains — Triple‑Layer Carbon & Pre‑Fil

VANVE 32-piece replacement filter kit supplies carbon filters and pre-filter sponges to keep cat and small‑dog fountains delivering cleaner, clearer water.

If you own a 67 oz (2 L), 95 oz (2.8 L) or 135 oz (4 L) automatic pet drinking fountain, maintaining fresh water depends on regular filter changes. This kit contains 16 triple-layer replacement filters plus 16 pre-filter sponges sized to those popular reservoir models so you can swap parts routinely without hunting for single items. Each filter combines a non-woven fabric, activated carbon and ion exchange resin to trap hair, reduce tastes and capture certain minerals, while the sponges catch debris before it reaches the pump.

How do these replacement filters improve fountain water quality?

The VANVE filters use a three-stage construction to remove visible particles and reduce impurities that affect flavor and clarity. Activated carbon adsorbs odors and chlorine-like tastes, the ion-exchange layer helps with certain dissolved minerals, and the fabric prevents hair and larger debris from re-entering the reservoir.

• Triple filtration: non-woven fabric + activated carbon + ion exchange resin
• Reduces odors and off-tastes for more appealing water
• Minimizes particulate matter that can clog pumps and nozzles

How often should I change filters and sponges to keep my pet’s water fresh?

Replace the carbon filters every 2–4 weeks depending on usage, water hardness and how many pets drink from the fountain. Swap pre-filter sponges more often if they visibly collect hair or debris; replacing both on a schedule helps prevent pump strain and maintains flow.

• Soak each new filter 2 minutes before first use for best performance
• Change filters every 2–4 weeks; sponges as needed or with each filter swap
• More frequent changes recommended for multiple pets or hard water

Will these cartridges fit my pet fountain model?

The kit is designed for compatibility with 67 oz (2 L), 95 oz (2.8 L) and 135 oz (4 L) pet drinking fountains, but check the physical filter dimensions to confirm fit. Each filter measures 3.9 x 3.9 x 0.4 inch and each sponge measures 1.5 x 1.1 x 1.0 inch, so you can compare with your fountain’s existing parts.

• Filter dimensions: 3.9 x 3.9 x 0.4 inch; sponge: 1.5 x 1.1 x 1.0 inch
• Includes 16 filters + 16 sponges — bulk pack for regular maintenance
• Confirm model compatibility before purchase to ensure correct fit

How does this kit help extend the fountain’s pump life?

The included sponges act as a pre-filter that traps hair and solid debris before they reach the pump, lowering the likelihood of blockages and mechanical wear. Clean, well-filtered water also reduces sediment buildup on pump components, which can prolong reliable operation.

• Pre-filter sponges prevent premature pump clogging
• Less sediment on pump parts reduces maintenance and noise
• Routine filter changes support consistent flow and longevity

Who is this for: Pet owners who want an economical way to keep fountain water clean and pumps running smoothly. The VANVE 32-piece kit suits households with one or more cats or small dogs using compatible 2 L, 2.8 L or 4 L fountains, and for anyone who prefers buying replacement filters and sponges in bulk to simplify regular maintenance. Always confirm your fountain’s filter dimensions and replace parts on a steady schedule for best results.
