6pk Replacement Filters for 3L Catit Flower Fountain

6pk Frameless Replacement Filters for 3L Catit Flower Fountain  The Triple Action Fountain Filters for Catit are designed to help remove odors, impurities and filter out debris from the cat water bowl.  The ion exchange resin helps soften minerals like magnesium and calcium in tap water. The active carbon removes odors and impurities. The mesh material is also great at capturing large debris, which keeps the water and the fountain clean.  Triple Action filters are guaranteed to safely and optimally purify your cat's drinking water for approximately 30 days. After that time, filtration effects will start to gradually decrease and bacteria may start to form within the fountain reservoir.  Replace your Triple Action Filter for Catit every month, or sooner, if the filter is visibly saturated.  These are designed for use in the 3L Catit Fountain models, see last photo 😸👍
