AquaSential™ Tankless RO Drinking Water System

Aqua-Cleer Advanced Drinking Water System

Small footprint. Big Results

 Just because you don’t have a lot of space, doesn’t mean you can’t have great water.

All you need is the Aquasential Tankless Reverse Osmosis (RO) form Culligan with it’s sleek, space-saving design.

While most RO systems use a tank, our Tankless RO uses a booster pump plus a 600 GPD (gallons per day) membrane to provide an unlimited supply of filtered, great tasting water.  With four stages of filtration, it’s the advanced drinking water system that works in almost any space.

    Your local Culligan Man can recommend the right solutions for you.

    *Contaminants are not necessarily in your water.

    Aqua-Cleer Advanced Drinking Water System
    Advanced Filtration, Customized for Your Unique Water Needs.
    Water quality can differ across regions, or even different homes and offices in the same town. This is why we developed Culligan Aqua-Cleer®. With 14 interchangeable filters we can customize the right solution specific to your water type. With Aqua-Cleer®, every glass is perfectly calibrated just for you.

    5 stages of filtration allow for complete customization:

    • Sediment filters screen out large particles like sand and dirt.*
    • Carbon filters improve water’s taste and odor.*
    • Reverse osmosis filters reduce dissolved substances such as radium, lead, arsenic-5, and others.*
    • Optional specialty filters are available to protect against specific contaminants such as arsenic-3, perchlorate, and volatile organic compounds.*
    • A second carbon filter ensures your drinking water is clean and fresh.

    Your local Culligan Man can recommend the right solutions for you.
