Culligan - $2352 ($2053 w/o R/O unit) Culligan Gold Series (10), Good Water Machine. If I were to look at price only, I would go with either the cheaper Ecowater system w/R/O at $2698 or the Culligan system. At almost $4k, the Kinetico system seems greatly over priced.
The Culligan brand is considered as one of the famous brands in the water softening industry. An âold dogâ in the business, their line of softening products has been in used since the 1940âs and still getting steady sales year after year. Are you planning to buy a water softener system from this brand?
