The quality of many types of coffees, teas, and powdered drinks begins with having great quality water. Water distillers improve the taste of water from the tap by taking out contaminates. These countertop devices listed on eBay use electricity to distil a gallon of water in five hours, and many use charcoal filters to remove impurities, such as chlorine and suspended particles. Distilled water beats all forms of bottled and tap water simply because both types include bacteria and added minerals, even if the water was originally distilled. Many health advocates advise using home water distillers to remove up to 99 per cent of impurities, including inorganic molecules that change the taste of water or could adversely affect your health. Since the water is not stored for long periods of time after the distillation process, bacteria has less time to recontaminate the container or grow to large amounts. Therefore, to get the best tasting, healthiest beverages for your home, switch to distilled water from your own machine.
