I have extreme amounts of iron in my private well water, as well as a strong sulfur smell and brown tint to the water. If you have water issues like this, I strongly recommend getting several quotes before choosing one, as I got many different recommendations and a wide range of quotes. One salesman even wanted $6000 for his! Steve was not the cheapest, but the price was reasonable and addressed all my water issues using one product. I spoke with 5 A-rated companies before choosing Aspen. The dealer, Steve, was very knowledgeable about his softener/filtration system and demonstrated how it would purify my water using a small replica of the one he would install. When I asked for more written information about the manufacturer and asked more questions by phone and email, he was very responsive. The manufacturer, ATS, is family owned and has been in business for almost 50 years. The installer was experienced and thorough. He set up the system so that it would backwash outside into the ground and not into my new peat septic, which cannot handle salt, as I requested. The water is now clear and clean and my dishes and white clothes, nails and hair are no longer literally turning brown. Steve will be back in a month to retest the water as part of his service, which I think shows that he wants to make sure the water is a pure as possible and that he backs what he sells.
