I am on a well and the water supply for my humidifier comes from my water softener. I’ve been told that I should move the water supply for the humidifier before the water softener. What do you recommend?
It really does not matter if you are using hard water or soft water. Both are just fine for the 400 humidifier. One is not any better than the other in performance of the humidifier.
Please let us know if you have any further questions.
