My wife has been ill for a few years now and she is recovering from her illness. When we were visiting with her physician on a weekly basis, we mentioned that we were in the process of building a new home and we were looking for a complete water filtration system. Our doctor immediately recommended Pure Effect Filters so we did some research and decided to purchase the ultra city water whole house filtration system. It has been the best purchase for our new home and we feel so confident that we are getting water at its purest form. Even the plumber told us when he was installing it, this system has to be the best water filtration system I have ever installed. WE LOVE IT!
