I to had the problem of trying to sort through all the confusing contridictions relating to water softerners.I have chosen the pelican no salt,and i have well water.I did not want to taint the tast of my water with a salty tast.My water tast was excelent and tested for very good quality, except for the hardness. The pelican did take away that hard to clean build up on all our faucets and my wife and i notice a big difference in the feel after taking showers.Skin feels not as dry as before and all water appliances now stay very clean.I have only had the system installed for about 6 months.so as far as longeventy we will see???I am not in anyway assoiciated with any company.I do however wonder why there isn't more research and proof reguarding this all important topic.i find reading all the information reported by the many water filter companies to be in many cases only self serving. GOOD LUCK.
