Elevate your pet's hydration with Invengo's MeowFlow replacement filtration set. This upgraded 12-pack combines 12 carbon filters and 12 foam sponges designed for seamless compatibility with Invengo MeowFlow pet water fountains.
Each filter features a four-layer system of non-woven fabric, activated carbon, ion exchange resin, and Maifan stone. This arrangement helps reduce hair, dust, chlorine, and metals while preserving the water's quality.
Maifan stone naturally releases minerals and can help balance water pH, contributing to a cleaner, potentially more refreshing drinking experience for pets in daily use.
In practical terms, the foam sponge captures hair and debris before they reach the pump, helping to minimize clogs and maintain a smooth, quiet fountain operation.
For best results, rinse the filter and sponge before first use and replace every 2–4 weeks. The tool-free installation makes swapping components quick and straightforward.
Designed for Invengo MeowFlow series fountains, this upgraded 12-pack offers ongoing filtration support without frequent replacements. Usage results can vary, but many pet owners report fresher water and steadier fountain flow over time.
