The Premier Pet® Fountain provides your pet with 50 ounces of fresh, filtered water. The submersible pump circulates the water through two filtration systems: a foam filter, to remove dirt and hair, and an activated carbon filter, to remove bad taste and odor. Cleaning the fountain and replacing these filters at least once a month ensures the freshest water and a long-lasting fountain. The BPA free plastic design comes apart for easy cleaning and is top-shelf dishwasher safe (excluding the pump). The continuously moving water prevents bacteria growth, keeping the fountain cleaner than a standing water bowl, and encourages your pet to drink more. Your pet will have the option to drink from the free-falling stream or the shallow bowl. By drinking more, your dog or cat will stay properly hydrated, promoting a healthier lifestyle and a happier pet.
