One gallon of distlled water can cost over $10. You can make your own distilled water for as little as $0.40 per gallon. Distilling water is the best way to purify water. It removes chlorine, fluoride, lead and other heavy metals, minerals and salt. Also kills bacteria, viruses and protozoan cysts. Purify your drinking water in case of a natural disaster or contamination of the drinking water supply. Eliminate the waste generated by buying water in plastic bottles or by replacing filter cartridges. Purify your water naturally and store it in reusable containers. The Condenser and water pan can also be used as a double boiler, stock pot, stainless steel bowl or ice bath. See the rendering video below to see how you can use the distiller for rendering lard or tallow.
