Staying hydrated is imperative for your pets’ health and wellbeing in the long term. Together, Purolite resin and activated carbon optimize water by providing both mechanical, and biological filtration. Think debris, hair, chlorine, organic chemicals and metals, the filters get rid of every impurity, making the water fresh, safe and clean for pets. The activated carbon can eliminate excess alkalinity and carbon, ensuring the water is odor-free and tasty. The replacement filters are easy to install, use and operate. Just rinse them well with water, install them and let your beloved pets savor fresh pure water. Quality comes by default, as the filters are made of superior granular active carbon and polymer resin. They perform better and last longer than ordinary filters, meaning you have minimal replacement hassles. Note that, replacing filters every few months is recommended to uphold water quality. The replacements should be more frequent if you have more than two pets drinking from the fountain.
