Drinking Water Solutions

A Culligan® Aquasential™ Reverse Osmosis Drinking Water System provides great tasting water every time. Our units use the most advanced technology available, which is able to reduce impurities and contaminants far more effectively than carbon filter pitchers and faucet filter attachments. Never worry about chlorine, "rotten-egg smells" and foul tastes when you rent or buy a Culligan® Aquasential™ Reverse Osmosis Drinking Water System!
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. Learn more about the revolutionary ClearLink PRO™.
If space is a concern, Culligan now offers an Aquasential™ Tankless Reverse Osmosis Drinking Water System. It provides a continuous flow of water, features a sleek, modern design and is less likely to leak than a traditional RO system.

What Clients Say
Having two little kids in the house made our drinking water a top priority. We looked into water delivery and some other options but were not sure what would be best for our family. After a professional from Culligan Water came to do water tests, they walked us through all of the options and helped us to make a decision that was best for our family. Peter answered ALL of our questions (and trust me, I had a lot!) was so kind, and did an amazing job of following up. We ended up choosing a full house system. Install was seamless and the professionals were cautions of COVID protocols and really explained the system to us after they were done. We were pleased with the work and are now comforted that ALL of the water in our house (including our hoses outside!) are safe for our kids. Highly recommend!
