Thank you for your excellent question. As a starting point, I want to clarify that we use distillation as our core treatment technology because it consistently removes the largest range of contaminants, but we also incorporate other treatment methods into our water distillers. There is no treatment process that is perfect, distillation included.
A good rule of thumb is that distillation is extremely effective in removing contaminants that have a higher boiling point than water, which is the vast majority of contaminants. There are some inorganic and organic chemicals that have a lower boiling point than water, such as chlorine. We handle this in two ways…
First, our distillers incorporate twin volatile gas vents, a patented feature. These are two small holes that allow gases that are lighter than air, such as chlorine to harmlessly vent out.
Second, all of our water distillers incorporate carbon filters, which are very effective at removing these gases that still happen to be present. Since we are running distilled water through the carbon filters we can make these filters last a very long time and we avoid the normal problems of carbon filters which include bacterial contamination.
We have tested the effectiveness of our machines on chlorine with and without a carbon filter. Without a carbon filter we achieved a 93% to 95% removal rate of chlorine. With the carbon filter we achieved a 99% plus (which means that no chlorine was detected).
