Feel confident with every sip that you are getting nothing but the best for you and your family. The Aquifer Refinewater filtration system with Kohler connects voice-activation technology and effectively reduces contaminants including bacteria, viruses, lead, mercury, chlorine select pharmaceuticals, VOC, 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.

The redesigned stainless steel hot water tank (HWT-F1000S), which includes the new water filtration system (F-1000S), will feature a new high-end appearance. It is re-engineered for longer life and improved performance with a 2/3-gallon capacity tank, tool-free connections to ease installation, and dry-start protection for peace of mind. This tank provides up to 60 cups of steaming hot, filtered water per hour.

Feel confident with every sip that you are getting nothing but the best for you and your family. The Aquifer®+ two-stage water purification system effectively reduces contaminants including bacteria, viruses, lead, mercury, chlorine, and pharmaceuticals in your cold water. While many other systems use coal-based media filters, Aquifer+ uses two recyclable filters: A carbon block filter made of ground-up coconut shells and a filter made of hollow fiber membrane. Under-sink installation is fast and easy, and the compact Aquifer®+ system fits alongside garbage disposals and household items stored below the sink.

Installed the system relatively easy. Had to go to a plumbing store to buy different parts to connect to my beverage faucet that was not a Kohler faucet. The only thing that was inconsistent was the picture on the site shows a brass T fitting and the unit comes with a plastic T fitting. This is somewhat deceiving for the price you pay for the unit. But the end result is that the filtering system dispenses great tasting water. Both me and my wife are overall happy with the unit.. Mel T. Mon Mar 23 2026
