About this product

Oneisall 3.5L Corded Automatic Cat Water Fountain Filter Replacement is a set of eight replacement filters designed specifically for Oneisall pet water fountains. Each filter features a five-layer filtration system including activated carbon, ion exchange resin, non-woven fabric, and silver ion ceramic balls to remove impurities and debris. The filters help maintain clean, fresh water for cats by preventing pump blockages and ensuring consistent hydration. To use, soak the filter for five minutes, rinse briefly, then insert it into the fountain. For best results, replace every two to three weeks. Hand wash only. Ideal for households with multiple pets requiring more frequent maintenance.
