We are moving to a new home and will be on a well and septic system. We are trying to figure out the best way to treat our water. If we put in a water softner, do we need a water filtration system too? Do both systems do the same thing? What are the benefits to one system over the other? I understand that softners can help our water heater and other appliances last longer. Will a whole-house water filter help more? Any advice?
