Our water is okay. We drink it and wash with it, but the clothes are a little dingy. I have been researching water purification and ran across a "non-salt" based softening system. See http://www.greatwaterco.com/e-information-course-conditioners-carefree.phtml What I would like to know is whether these ideas are valid or is this just another high tech way to separate me from my money. I also have seen charcoal filters in the $500 -$1,000 range that do the whole house. Anybody have any experience with these? Thanks.
