The replacement carbon filters provided with my unit, were not adequate for removing VOC's.After exchanging an old filter with a replacement that's included with the unit, the distilled water had a pungent chlorine smell and taste.Ordered Quality Carbon filters, and some recommendations are to run water through a Brita first (pre carbon filter) then boil in a kettle, add to the machine, and water should be as close to 0 ppm with little to no VOC's.Otherwise
