Distillation is the process of removing contaminants such as heavy metals and salts that boiling water leaves behind. In this process, the water is heated up to its boiling point and the steam is collected. The steam will then be converted back into its liquid form leaving all the contaminants behind and making the water pure. There are a lot of water distillers available in the market with different sizes to choose from that will fit your countertop. All of them will remove approximately of the contaminants found in your water. Having water distillers will save you a lot compared to bottled water purchases. Individual bottled waters usually costs a dollar or more when purchased unlike having a water distiller. A gallon of water when distilled at home averages 25 cents, and the initial purchase of a distiller will cost you between 400 to 650 dollars, but it will surely pay for itself quickly. You no longer have to buy bottled waters and spend hundreds of dollars every year on the wasteful product when there are healthier alternatives.
