Water distillers can actually allow a tiny percentage of impurities, voc’s to migrate into the storage container during distillation. Voc’s including some pesticides and solvents, boil at temperatures below or very close to water (98 – 103° C) . Distillation alone might not be enough to remove voc’s. Distillers equipped to remove these substances have activated carbon post treatment filters.
Included with this product are 12 carbon sachets. Each sachet will last 20-30 distillation cycles.
