[For Swan Models] Designed specifically for Swan pet drinking fountains, our T-shaped suction cup water filters provide a seamless fit and optimal functionality. Each filter is crafted to effectively trap pet hair and debris, maintaining clean drinking water for your pets. [Effortless Installation and Secure Suction] Our cat fountain replacement cartridges are engineered with easy-to-install suction cups that attach directly to the water inlet hose. This design simplifies the installation process and secures the filter in place, preventing any bypass of unfiltered water. [Recommended Replacement Schedule] To maintain optimal water quality, we advise replacing the filter every 2-4 weeks, depending on usage. Regular replacement helps prevent build-up of impurities and ensures that your pet's water is always fresh and clean. [Preparation Tips for Optimal Use] For best results, we recommend soaking the new filter in water for 5 minutes and rinsing it thoroughly before installation. This pre-use preparation helps activate the filter media, ensuring effective filtration from the first use.
