“Good quality unit. Excellent directions. The Remineralization add-on is just another filter that you splice into the output line. They did not provide additional directions or retaining clips for the Remineralization filter.
My biggest issue which they do not tell you in the marketing materials or the directions is the concept of TDS creep. That is when the filter is not running, TDS will flow into the output water. To remedy this you have to run the faucet for about a liter or two before the TDS reaches the target range. This is a lot of water to put down the drain (not to mention the attendant drain water) before you get the water you want.”
