What We Do

Water Treatment from an Industry Leader

Culligan works to provide better water for our customers in their homes, offices, businesses and industrial facilities around the world. Our complete line of water softeners, water filtration systems, commercial and industrial water treatment solutions, drinking water systems, whole-house filtration systems and bottled water delivery set the standard in the water treatment industry.

Culligan was established in 1936 as provider of water softening solutions for residences, and has since grown to becoming a worldwide leader in water treatment needs, from the simplest filtration system to complex industrial water solutions. You can count on your local Culligan Water Expert.

A History of Innovation

When Emmett J. Culligan founded the Culligan Zeolite Company in 1936, it was with the idea of making conditioned water available to homeowners. He not only pioneered new water treatment methods, but based his business on a service model and established a network of franchises, a strategy that helped the company grow far beyond the Northbrook, IL, community where it was founded.

With the founding of the company came the Culligan brand, one that has grown from local word-of-mouth acknowledgement to national recognition, thanks to print ads premiering in Life Magazine in 1947 and radio commercials introducing Hey Culligan Man!® in 1958. As our recognition grew, franchises expanded, and product lines broadened, we changed our name to reflect our growth, first to Culligan, Inc. in 1952, followed by Culligan International Company in 1970.

In the years since, Culligan has evolved into a world leader, creating innovations that have helped shape the water industry while setting standards for quality improvement and customer service. In 2007, our headquarters moved to a new building in Rosemont, IL, with the only state-of-the-art analytical laboratory certified by the State of Illinois EPA to be compliant with National Environmental Laboratory Accreditation Conference standards, setting the stage for new advancements and future growth. In 2008, we reinforced our commitment to making the world a safer place to live by introducing new products with improved efficiencies that are better for the environment.

Today, Culligan is proud to have provided world-class service and innovative water treatment solutions for more than 85 years, from the simplest filtration system to complex industrial water solutions.

Social Responsibility and Commitment

The most important lesson we learn from our work with water?

We’re all in this together.

We’re committed to making our efforts, large and small, beneficial for everyone in every community we serve. We believe in supporting the health of our communities, the health of the environment, and we come to work every day dedicated to doing great work that reflects these values.

To us, being responsible stewards of our water supply, our communities, and the environment is the least we can do.

We wouldn’t be anywhere without the communities we serve. We’re here to help those communities, wherever and whenever we can.

Culligan participates in disaster relief programs globally and locally through Culligan Cares™, while Culligan International regularly partners with Convoy of Hope to provide clean water for those in need following a disaster. Most recently, Culligan International and Culligan Dealers provided bottled water through Convoy of Hope to the victims of Hurricane Sandy and the devastating tornadoes in Oklahoma. Your local Culligan Water Expert also participates in your community, supporting local events, providing water in an emergency, and leading the area in local water issues.

Happy customers and a happier planet should never be mutually exclusive.

At Culligan, we’re committed to delivering state-of-the-art products and water solutions that benefit our customers, while minimizing the impact on the environment. Some of our innovations in this area include the Culligan High Efficiency series of water conditioners, and Culligan’s innovative bottleless coolers that help homes and businesses reduce the use and disposal of single-serve plastic drinking water bottles.

Doing a good job for our customers, our communities, and our environment is what drives us, and what connects us, because we are all in this together.
