  1. Yes, water bottles are also infinitely wasteful & harmful to the environment. It is why it is essential to provide clean water to use at home, as it leads to any household member’s safety. Not only does it keep you safe, but it also lets you save more money because bottled water would not be required.

  2. #4 the copper coil isn’t distilling all the water only heating it and there is no way to determine if all of it boiled hot enough to kill all the bacterias. If you carry a thermometer and the water temperature in the end cup is over 180F your good to go. A true distiller only allows the boiled water vapors and steam to travel up a pipe to a high point, higher than the water level at the start point. The vapors and steam then condense on the way down the cooler side of the pipe coil becoming purified water.
