Great solution for Arizona hard water
After just one day, we could notice the difference. Smell and taste of tap water were much better, and my wife noticed a huge difference when she washed her hair. Arizona has some of the hardest water in the country, and this system made a difference. My only complaint was that the filters shipped with the big blue 10” sediment filter were filtteck brand made in Taiwan which appear to be slightly too long. This doesn’t allow the filter container to seal when screwed in and leaks. (I screwed the canister on with no filter in it and no leaks. I am waiting for new filters.) I am still giving 5 stars because Francis in customer service/tech support is sending a different brand filter to see if that fixes the leak and he is following up with my issue nicely.
