Do some contaminants carry over with the steam in the distillation process?
Some contaminants that have boiling points lower than that of water could carry over, which is why these distillers are equipped with a safety feature: a volatile gas vent, a design feature which removes most of these contaminants. For even further protection, each distiller is also equipped with a carbon post-filter to provide you with the highest quality distilled water with a 99% or higher removal rate of contaminants.
