Cat Water Fountain Replacement Filters PF1/PF1L

These replacement filters use eight-layer filtration to remove pet hair, odors, and common contaminants from your cat's drinking water. The system combines activated carbon for odor removal, ion exchange resin to soften water quality, and KDF material to filter organic matter—all working together to provide cleaner, safer water than standard four-layer filters. The multi-stage approach addresses specific health concerns. Mineral ceramic balls help regulate pH toward a weak alkaline level, while the filtration design reduces the organic compounds that can contribute to kidney stone formation and other urinary issues in cats. Each filter lasts approximately 30 days depending on usage. Before first use, soak the new filter in fresh water for at least 10 minutes. After installation, update your fountain's cartridge cleaning settings to keep the system running at peak performance.
