We have hard water in our area. We installed the Honest Water Filter 8 months ago and noticed our skin was softer right away without the slick feeling we had with our old salt softener. We were also getting pinhole leaks in our plumbing which has not been an issue since installing an Honest Water Filter. We also have more room in our garage since getting rid of the salt softener, too. Happy I don’t have to pay for or haul salt now.
