What Is the Average Cost of a Culligan Water Filtration System?

Because Culligan only does direct sales, customers need to have a service representative come to their home or business to give a cost estimate. However, a basic ion-exchange water softener costs between $400 to $1,000, while installation costs another $100 to $500, as of September 2015.

A unit for a larger home can cost anywhere between $1,000 and $2,500, and the installation can raise the price to $3,000 or up to $10,000. Because water filters need periodic maintenance, the price of owning one increases. Customers who rent a Culligan water filtration unit receive free service and repairs on their systems, eliminating this additional cost.

Customers who get a Culligan water filtration can purchase a basic unit, but additional features and add-ons cost extra. Additionally, the cost of services, repairs, deliveries and fees varies depending on if the customer rents or purchases a unit.
