"Filtered tap water is not ideal either. If you read the fine print, common filters do not filter out the chemical chlorine, just the taste. A potentially more serious problem is that charcoal filters can harbor bacteria. A filter must be changed regularly. Filtered water can lead to infections under certain circumstances, care must be taken to keep the filter, and the surroundings as clean as possible. Charcoal may attract and hold contaminants, but it is not antibacterial."
Did you see the picture of the "typical" distiller machine that I posted? Is that like yours?
Doesn't your distiller have a filter on the spout? It should as ALL other models do and are recommended to have. Distilled water can contain VOC's because the chemicals have the same boiling point as water, so they are brought up in the steam. The only way to remove them is thru a charcoal filter! Also any inorganics that may be leached from the water pipes can be removed in the filter too!
