A: Verified Culligan Water of Sonoma County Customer, 1 of 618 "I've tried a lot of different options, but I think this is the best system that I could have ever purchased. If I ever leave this house, I'll have the same one installed by Culligan in my new place. It tastes wonderful. We aren't able to use it right now due to damage in our house, so we have been buying bottled water. The other day my son turned to me and said that the bottled stuff doesn't taste as good as Culligan's, and I agree. We are loyal Culligan fans." - Ella K.
