        Q:Does the filter help with hard water and calcium in my water. I have well water
        by|Jul 26, 2022

        Answer This Question

        A:  I have well water and it does but I would recommend the second big item conditioner I believe with the whole system if you can afford it. I currently am only on the main filters and I have no problem with my water nor any smell.

        by|Aug 2, 2022

          A:  The "hardness" is dissolved minerals, including calcium. I don't think simple filtration will remove this, you need a specific softener. We have an Aquasana softener and it works pretty well. I think they also have products specifically for well water.

          by|Aug 2, 2022

            A:  Hello, The Whole Home Post-Filter will help reduce sediment or silt in the water. We believe your question(s) will be best answered by a Whole Home expert. Please contact us directly at 866-662-6885 Option 2, Monday thru Friday from 8 am-5:30 pm CST.   -Aquasana Customer Support

              System still working as advertised
              I can always tell when the system filters need to be changed due to the clear filter housings. It's so easy to accomplish with the way it is set up.

              Amazing filter!
              I really wasn’t sure these filters were doing anything to improve my water. After 3 months we checked it and it was black with particles trapped from our water! Replace these often! They are amazing!

              Not sure I'm impressed...
              The post filter, upon replacement, is definitely doing its job of removing sediment and such from our water, but I can't say that I'm impressed overall. We are on a private well, but we purchased the appropriate system for our needs. I still have to remove shower heads and faucet aerators on a regular basis to improve flow and pressure six months after installation. I have not noticed a discernible difference in taste since installing this system, although that was not an issue to begin with, but I can tell at pre and post filter replacement that the filters are doing something.

              Water for Life program
              Horrible program, don't sign up for it. They charge and don't send filters. Don't send the right filters when you tell them what you want. Try to update card on file for them to charge but they don't get it right.

              Horrible system!
              All the water in the house is black. The water directly out of the well looks better than post filter.

              I like it when things work as expected.
              Everything went well. This product is great! Great water without noticable loss of pressure.
