What We Do

Water Treatment from Industry Leader

For nearly a century, Culligan has been a pioneer in water filtration. Starting with Emmett Culligan’s very first water filter made out of a coffee can and greensand back in 1921, we’ve been on the forefront of innovation in water treatment systems and servicing water treatment products. Today, Culligan continues our efforts to bring the purest, softest, cleanest water into homes, offices, restaurants, and industrial facilities around the world with our water treatment equipment. 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.
