【Compatibility】：Please check the main images and product details to confirm whether this filter fits your 360° stainless steel pet water fountain or cupcake-style pet drinking fountain. For other fountain models, compare the filter shape and size to ensure matching. You can find matching replacement filters for other shapes in our store for purchase.
【Regular Filter Replacement】：We recommend replacing filters and sponges every 1–2 weeks to maintain high-efficiency filtration and supply fresh, premium-quality water for your cats. Higher water intake helps lower the risk of urinary tract infections in pets.
【Multi-Layer Filtration System】：This cat fountain filter is made of natural cotton fiber, activated carbon and ion exchange resin, and is BPA-free. Activated carbon purifies water and eliminates odors; ion exchange resin absorbs trace heavy metals and softens water; foam sponge blocks pet hair, dust and food residues.
【Easy To Use】：Rinse the filter under clean running water for 2 minutes before first use to wash away loose activated carbon dust and activate its filtering performance, allowing the filter to reach optimal working condition quickly.
【Kind Reminder】：Filter dimension: 1.5×0.6×1.0 inches; Sponge dimension: 2.5×1.0×3.1 inches. Always thoroughly rinse the cat fountain filter with clean water before installation to deliver the best filtration performance and clean drinking water.
