Distilled water vs purified water can be difficult to figure out, but it is easy when you know where the two come from. Pure water is removed through distillation and then the sanitizer is added to the resulting product. The result is not only good tasting, but also safe drinking water. It is no wonder that distillation is the most popular purification method used today. This is the best way to remove contaminants from tap water and ensure that your drinking water is pure all the time.
