According to the instruction manual, it is recommended to replace the filter and sponge of water fountain at least once a month if you have one pet. If you have multiple pets, you may need to change them more frequently if they become clogged or soiled. Regularly cleaning and changing the filter and sponge helps to prevent the build-up of algae and ensures clean and fresh water for your pets.
