Take Filtration One Step Further
Culligan tankless reverse osmosis systems offer four stages of filtration and are certified to reduce the metals, salts and minerals in your water known as TDS (total dissolved solids). You can also enhance your system with these additional options:
Premium Faucet
Choose from four modern designs in brushed nickel, chrome, matte black and bronze, and check real-time insights into water quality and filter life on the electronic display.
ClearLink PRO™
Instead of adding a second faucet, use your existing faucet and switch between RO and tap water at the touch of a button. The display also shares information on filter life and water quality.
Mineral Boost+ Cartridge
Upgrade the final stage with this option that includes carbon filtration and also adds calcium, magnesium and potassium for optimally alkaline, pH-balanced water.
Third-Party Certified
The Aquasential Tankless RO and Aquasential Tankless RO with Mineral Boost+ have been tested and certified by WQA against NSF/ANSI 372, CSA B483.1 and NSF/NSF 58 for the reduction of TDS as verified and substantiated by test data. Learn more about product certifications here.
