  1. I am interested in more information on the Aquasana system. Generically, what media is used to achieve the Nucleation Assisted Crystallization. I can only surmise that they are permanent magnets.

    1. Hi Michael

      This is a question best asked directly to Aquasana because they can give you a more accurate answer. I would only be guessing.

      Stay hydrated,

  2. Aquasana, could you please put your ad on Facebook. Lots of people that live on Lake Livingston in Texas could use some help… We all keep getting letters from our water Co. that they failed the state test and not to drink the water… I highly recommended your water systems.
