Feel confident with every sip that you are getting nothing but the best for you and your family. The Aquifer Refine water filtration system with KOHLER Konnect voice-activation technology, effectively reduces contaminants including bacteria, virus, lead, mercury, chlorine select pharmaceuticals, VOC's and more in your cold water. While many other systems use coal-based media filters, Aquifer Refine uses three recyclable filters: two carbon block filters and an ultra-filter. Under-sink installation is fast and easy, and the compact Aquifer Refine system fits alongside garbage disposals and household items stored below the sink.
