Four-Stage Filtration Process

2-in-1 Sediment and Carbon Filter

Address materials — like dirt, sand, and rust for a more refreshing water experience.

High-Capacity Solution

Tackle even more contaminants with a specialized, semipermeable membrane that provides comprehensive filtration.¹

Carbon Block Filter

This final polishing stage targets any remaining bad tastes and odors so you can enjoy crisp, fresh-tasting water with every sip.

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.
