The high quality genuine 3 stage filter cartridges have been designed to maintain clean, fresh tasting drinking water for your pet when fitted to your Cat Mate or Dog Mate Pet Fountain. These cartridges are triple action. Firstly, the fine polymer filter fibres trap hair, dirt and food residue thereby improving the life of the pump. Secondly the highly activated filter carbon removes odours including chlorine and greatly improves the taste of the water, making it attractive to even the fussiest pets. Thirdly the ion exchange resin helps prevent harmful scaling deposits by softening the water. The cartridges arrive individually wrapped and should be rinsed in cold tap water before use. These should be replaced monthly, or sooner if they become clogged. Never run your Cat Mate or Dog Mate fountain without a genuine Pet Mate cartridge fitted. They will fit our whole range of Cat and Dog Mate Fountains. All Cat Mate and Dog Mate feeders, fountains and product accessories are manufactured from food grade, BPA free plastics.
