I just did a double filter and test. The tap was 280 mg of shit per liter. RO was 50 mg/L. RO then Distilled was 11. Certainly if you do that combo, it doesn't matter what was in there, nothing is in there now.
Also RO should be taking 350 mg/L of shit down to 15 by itself. Dunno what's going on there.
