How it sells

Home systems (softeners, whole-house filters, RO) are sold, rented, financed, installed and serviced through local Culligan dealers, a mix of franchised independent dealers and locations Culligan buys and runs. Pitchers, dispensers and gravity countertop filters ship direct from shop.culligan.com, and the brand’s return policy refers to purchases from retailers.

Installation

Softeners, whole-house filters and RO systems are installed and maintained by the local Culligan dealer after a free water test or consultation. Pitchers and gravity units need no installation.
