Culligan launched the Culligan Zeolite Company (Water Softening) in Northbrook, Illinois. During WW II, Culligan built a facility to manufacture silica gel, a dehydrating material that protected metals from atmospheric corrosion that was greatly in demand during the war, and Culligan soon became one of the largest suppliers. He developed a novel process for manufacturing zeolite, the man-made mineral used in water softeners, and built a nationwide service industry in water conditioning and filtering, which then expanded internationally.
