PETLIBRO Dockstream Cat Fountain Replacement Filters, 6-Pack with Pre-Filter Sponges, 3-Month Set

PETLIBRO replacement filters are made for selected Dockstream cat fountains, with six filters and six pre-filter sponges for multi-layer water filtration.

• Six filters and six pre-filter sponges — a three-month set when filters are replaced every two weeks.
• Multi-layer filtration — designed to filter impurities and provide oxygen-enriched, better-tasting water.
• Activated carbon and ion exchange resin — target foul odors and heavy metal ions while softening water quality.
• Non-woven fabric and a built-in pump sponge — capture hair and debris to help prevent blockages and pump damage.
• Five-minute soak and 30-second rinse before use — prepares each filter for installation.
• Compatible with five PETLIBRO fountain models — fits PLWF105, PLWF115, PLWF106, PLWF116 and PLWF005.

These replacement filters are for cat owners who want to maintain filtered water in a compatible PETLIBRO fountain. The pack includes the filter and pre-filter components needed for routine replacements, with each component individually packaged. If you have multiple pets, the fountain may need more frequent cleaning and filter changes.

Which PETLIBRO fountains do these filters fit?

These filters fit only the PETLIBRO Cat Water Fountain models PLWF105, PLWF115, PLWF106, PLWF116 and PLWF005. Use official PETLIBRO filters for these fountains; off-brand filters may cause leaks or pump failure in PETLIBRO automatic water dispensers.

• Designed for the five model numbers listed above.
• Check your fountain’s model number to confirm compatibility.

What comes in the replacement filter set?

The set contains six replacement filters and six replacement pre-filter sponges. The filters and sponges are packaged separately, so you can prepare each component for use as needed.

• Six replacement filters.
• Six replacement pre-filter sponges.
• Six-filter set described as a three-month supply.

How do the filters work, and how often should I replace them?

The vertical filtration system uses several layers to filter water and capture debris. Activated carbon targets foul odors, while ion exchange resin removes heavy metal ions and softens water quality. Non-woven fabric captures cat hair and impurities; the built-in pump sponge further filters debris to help prevent blockages and damage.

• Before use, soak the filter for five minutes and rinse it for 30 seconds.
• Replace filters every two weeks to maintain filtering performance.
• With multiple pets, clean the fountain and change the filter more often.

This PETLIBRO set suits owners of the five compatible fountain models who want replacement filters and pre-filter sponges for scheduled maintenance. Its model-specific fit, six of each component and layered filtration make it a practical match for keeping a compatible fountain’s water filtered.
