SORON Cat Fountain Replacement Filters, 20-Pack with Pre-Filter Sponges for PETLIBRO Models

SORON cat fountain filters are replacement filters for compatible PETLIBRO fountains, supplied as 20 filters and 20 pump pre-filter sponges for routine water filtration.

• Fits PETLIBRO models PLWF005, PLWF105, PLWF115, PLWF106, PLWF116 and PLWF305 — choose replacements for these fountain models.
• Four-stage filtration — addresses odors, heavy metals, water hardness, pet hair, debris and particles.
• BPA-free filter material — provides a BPA-free filter option for your pet’s fountain.
• 20 individually wrapped filters and 20 pre-filter sponges — keep replacement components separately packaged.
• Recommended filter replacement every 2 weeks, or more often if needed — follow a regular refresh routine based on fountain use.

These replacement parts are made for households using a compatible PETLIBRO cat water fountain and wanting to refresh its filtration components. The filter stages address common water and fountain concerns, while a pump sponge helps catch particles before they reach the pump. Use the included preparation steps before installing a new filter and sponge.

Which PETLIBRO fountains do these filters fit?

SORON filters are compatible with PETLIBRO fountain models PLWF005, PLWF105, PLWF115, PLWF106, PLWF116 and PLWF305. The filter measures 3.8 × 2 inches (9.65 × 5.08 cm), and the included sponge measures 1.5 × 1.18 inches (3.81 × 3 cm). Compare these model numbers with your fountain to choose a compatible replacement.

• Filter size: 3.8 × 2 inches (9.65 × 5.08 cm).
• Sponge size: 1.5 × 1.18 inches (3.81 × 3 cm).

How does the four-stage filtration work?

SORON cat fountain filters combine four filtration stages to address different types of unwanted material. Activated carbon helps eliminate foul odors, while ion exchange resin removes heavy metals and softens water. Fiber cotton traps pet hair and debris, and the pump sponge filters particles to help protect the fountain pump from damage.

• Activated carbon targets odors.
• Ion exchange resin acts on heavy metals and water hardness.
• Fiber cotton and the pump sponge catch hair, debris and particles.

What is included, and how do I prepare a replacement?

Each SORON set contains 20 filters and 20 pre-filter sponges, with every piece individually wrapped. Before use, soak a filter and sponge in water for at least 3 minutes, then rinse them for 30 seconds. Replace the filter every 2 weeks as a general recommendation, or more frequently depending on your pet’s drinking habits and how many pets use the fountain.

• Both the filter and sponge require soaking and rinsing before use.
• Filter changes are recommended every 2 weeks, with more frequent changes if needed.
• The filters and sponges are designed to be easy to remove and replace.

SORON filters suit cat owners with one of the compatible PETLIBRO fountains who want a supply of individually wrapped replacement filters and pump sponges. The multi-stage design is intended to help keep fountain water fresh and oxygen-rich around the clock, while the replaceable components support a regular filtration routine. They are made for the listed PETLIBRO fountain models and their specified filter and sponge sizes.
