Is distillation effective against organic contaminants?

Volatile Organic Chemicals (VOC's) are organic chemicals that have a boiling point lower than water, for example benzene.

When water is being brought to the boil in the boiling chamber of a distiller, these VOC's change into their gaseous phase before the water turns into steam and thus rise up with the steam as a gas. Any good distiller these days, uses a pinhole (a volatile gas vent) in the top of the condensing coils to vent off these unwanted gases.

If the VOC's do per chance escape these vent holes, the carbon post-filter will trap them. Distillation systems (such as the Dew Drop® Purewater production system) that use carbon pre-filters trap the majority of the VOC's before the water enters the boiling chamber.
