About This

[PERFECT COMPATIBILITY] Designed specifically compatible with Petlibro Water Fountains (Models: PLWF005, PLWF115, PLWF105, PLWF106, PLWF305). OEM-grade sizing ensures a secure fit with no floating or gaps, so water is fully filtered every cycle.
[SUPER VALUE 1-YEAR SUPPLY] Includes 25 High-Density filters and 25 Sponges. Based on a 2–3 week replacement cycle, this kit provides a full year of use with no monthly reorders. Fewer purchases, lower yearly cost.
[1.5X MATERIAL FOR MULTI-CAT HOMES] Packed with 50% more ion-exchange resin and activated carbon than standard cat water fountain filter replacement pads. This heavy-duty pet water filter system effectively removes chlorine, heavy metals, and odors while handling the saliva and "slime" buildup from multiple pets. The quad-filtration water fountain filters deliver crisp, fresh-tasting water that actively entices picky cats to drink more, supporting better hydration and urinary health.
[QUICK START & PUMP PROTECTION] To activate the carbon in these cat water fountain filters and sponges, please soak for 5 minutes and rinse for 30 seconds before use. Don't forget the pre-filter sponge! Changing it with every filter blocks hair from the Water fountain pump, extending the motor's life and keeping the automatic cat fountain quiet.
[FOOD-GRADE SAFETY TIPS] Made with strictly food-grade coconut shell carbon and safe non-woven fabric, making them ideal pet safe water fountain filters. If you notice carbon dust in the package, it is residue from shipping—simply rinse this cat water filter with clean water. Safe, odorless, and reliable for drinking water fountains for cats.
