Cat Water Fountain Replacement Filters 36 Pack

This 36-pack includes everything you need to keep your cat's water fountain clean and fresh for months. You get 12 carbon filters, 12 square sponges, and 12 black sponges—a complete multi-stage filtration system designed to work with DOOOB fountains and most stainless steel cat fountains on the market. Each carbon filter uses triple filtration: a cotton layer, activated carbon, and ion exchange resin to remove odor, soften water, and improve taste. The sponges trap pet hair, dirt, and food particles before they reach your cat's bowl. The result is cleaner, fresher water that encourages more drinking and better hydration. Before first use, soak filters in a separate bowl for 5 minutes and rinse for 30 seconds to remove any activated carbon dust. Replace filters every 1-2 weeks depending on fountain use and the number of pets. Check compatibility with your specific fountain model before purchasing to ensure proper fit.
