Experience Cleaner, Safer Drinking Water with Culligan Reverse Osmosis Drinking Water Systems

The Aquasential RO system is designed to accommodate the varying needs of contemporary homes, offering WiFi-enabled options, adjustable filters to suit individual water issues, and stylish appearances.

Culligan's RO systems use multi-level filtration which substantially diminishes the drinking water pollutants that cannot be seen, tasted, or smelled.

Culligan’s newest reverse osmosis system accessory, the Aquasential™ ClearLink PRO™, allows the user to go between filtered and unfiltered water without requiring any drilling into the countertops.

The use of optional intelligent technology allows you to set goals for water usage, monitor the amount of pollutants removed, keep track of your ecological footprint, and receive notifications for when it’s time to switch out the filters.

The specific financing terms supplied by an external provider, where applicable, can differ. The degree of the dealer’s involvement will vary. Please inquire with the dealer for more information. It is possible that contaminants may not be present in the water.

How Does Reverse Osmosis Work?

Reverse osmosis includes four distinct steps to perfectly filter your water: pre-filtration, reverse osmosis, drainage, and storage. Our multi-stage filtration process ensures the highest-quality water, addressing a wide range of potential contaminants and problems.

01 Pre-filtration

Water passes through a particle filter and activated carbon filter, reducing impurities like salt, sediment, chlorine, mercury, copper and pesticides.

02 Reverse osmosis

Pressurized water is forced through a semipermeable membrane, trapping the smallest impurities and allowing only water to pass through.

03 Drainage

The removed contaminants are flushed away while treated water moves to a storage tank.

04 Storage

Before the treated water reaches a faucet, it undergoes a final activated-carbon filtration to improve taste and quality for household use.

Enhanced water purity through the use of multi-stage filtration

01
Sediment filter traps rust, sand and other large particles
02
Carbon filter tackles bad tastes and odors, like chlorine
03
Reverse osmosis filter reduces contaminants like lead, mercury, chromium and more
04
Advanced specialty filters reduce pharmaceuticals, virus, bacteria and more
05

Commonly asked questions

Reverse osmosis is a process that reduces contaminants, solid substances, large molecules and minerals from water by using pressure to push it through specialized membranes. It is a purification method used to improve water for drinking, cooking and other household uses.

The key to understanding reverse osmosis is first understanding the process of osmosis. Osmosis is defined as the passage of a solvent, such as water, from a lower-concentration solution to a higher-concentration solution. A semipermeable membrane separating the two solutions allows the solvent to pass. But not what is dissolved in it. The flow finally stops when both solutions become equal in concentration. This process is classified as passive transport, because it does not require energy to be applied.

Unlike osmosis, reverse osmosis requires an external force to complete the transport. Therefore, pressure is a key part of the reverse osmosis process. And as its name implies, reverse osmosis is the opposite of osmosis. Instead of balancing out the two solutions, the external force of pressure reverses the natural flow.

Your home might rely on water treatment methods such as refrigerator filters, pitcher filters or faucet filters. While these options are effective at improving taste and reducing sediment or other particles found in drinking water, they don’t address dissolved solids, arsenic, viruses and bacteria. Reverse osmosis, on the other hand, is a type of water filtration that can reduce up to 99% of contaminants found in drinking water, including larger particles and those that you can’t always see, taste or smell.

A reverse osmosis drinking water system reduces a wide variety of contaminants that may be found in your water, including:

  • Lead
  • Mercury
  • Chromium
  • Chloride
  • Copper
  • Arsenic
  • Fluoride
  • Radium
  • Nitrate
  • TDS (Total Dissolved Solids)
  • Bacteria such as Salmonella, Shigella, E. coli
  • Protozoa, like Cryptosporidium and Giardia
  • Viruses such as Hepatitis A, Norovirus, Rotavirus

Yes, reverse osmosis water is a safe drinking water option for your household. The Water Quality Association has concluded that water treated with a reverse osmosis drinking water system does not pose any health concerns for healthy individuals. Consuming reverse osmosis water can help minimize health risks associated with potentially harmful substances that are sometimes found in drinking water.

Reverse osmosis is a water treatment process that reduces contaminants from water by using pressure to force the water molecules through a semipermeable membrane.

Distilled water is water that has been treated by passing through one or more evaporation-condensation cycles until it contains a very low amount of dissolved solids (usually less than 5.0 ppm TDS).

Distilled and reverse osmosis water are both commercially available, but reverse osmosis is more commonly used in home treatment systems. While some households opt to install a home distillation solution, these systems tend to be less convenient, and they usually require more energy and owner involvement to run.

Yes, the performance and longevity of your reverse osmosis system will be impacted by regular maintenance. However, top-performing reverse osmosis filtration systems tend to require little ongoing effort.

At a minimum, you should plan to change your filters every 1-2 years. You should also make sure your reverse osmosis drinking water system is sanitized once a year.

Selecting your reverse osmosis system from an industry-leading manufacturer and service partner will ensure that your system runs efficiently. Your local Culligan Water experts are equipped to handle every aspect of maintenance and ongoing care. From installation to filter changes and sanitization appointments, Culligan ensures that all parts continue working properly so you can provide your household with safer, better-tasting water.

Paige Harris

The entire team from Culligan was great. Garner was friendly and professional and did a phenomenal job of explaining everything in an understandable way. I’ve been having trouble with my appliances and he helped me understand the benefits of a whole home water softening system and a reverse osmosis unit for my kitchen sink. He did not pressure me. He’s very knowledgeable and just talked to me like a human being. Honestly, the system sells itself. I couldn’t be happier. My installer, Zach, was timely, professional and courteous. The service I’ve experienced by everyone has been top notch. And any questions I’ve had have been responded to immediately. The difference I have noticed with my appliances and faucets working better is remarkable and I feel better knowing that my family’s drinking water is safer (and tastes a heck of a lot better). Thanks Culligan!

Jennifer Hudspeth

Noticed a difference in how soft the water makes our hair feel. Using less soaps, lotions, etc… I’ve had issues with drinking water for years (it gives me heartburn). I was hoping to drink the RO water. Initially gave me heartburn so I went back to drinking distilled. I plan to test out drinking the RO water again. My family enjoys drinking it though. Overall, I feel better knowing my family has greatly reduced exposure to the toxins in our municipal water. Love Joanne, our sales lady. She’s so thorough and personable. Zack, our install guy was just as nice and explained what we had. Great experience with Culligan!
