These filters use a process called reverse osmosis, which pushes water through a semipermeable membrane. The membrane allows water to pass through, but not impurities or contaminants, which are then flushed down the drain.
Culligan® Aquasential™ Reverse Osmosis Drinking Water System are easy to use and maintain - simply change out the cartridges annually, or make a service appointment with your local Culligan Man™. Our compact units fit easily under a sink, and can be plumbed through your fridge, sink and even your ice maker.
Culligan now offers the ClearLink PRO™, which uses wireless technology to switch your main faucet between unfiltered and reverse osmosis filtered tap water at the touch of a button. No more drilling a hole in your countertop or losing a soap dispenser, which is required in a standard reverse osmosis system installation.
