JUST AS OTHERS ARE DISCOVERING GETTING DISTILLED WAATER IS BECOMING DIFFICULT....so decided to do my own, and after doing the set-up and the first run with cleanser, it became fast, easy and could do 2 a day, fill two gallon jugs: then put the machine away. Read the instructions and then use you common sense to figure out the actual workings: the first run with cleanser takes a very long time, I stopped it after 4 hours; but only takes a little less than 3 hours to complete a gallon.
