What does a Water Distiller do and how does it work?

Water distiller how it works

A water distiller purifies any water and removes all contaminants such as organic chemicals, inorganic chemicals and biological contaminants through the distillation process. A water distiller functions very simply.

You have a boiling vessel with a heating element at the bottom. This brings the water to a boil and starts a slow simmer. This action kills off any bacteria or viruses present. Interestingly boiling is the most effective way to kill biological contaminants.

The steam produced is pure water. It then passes into the condensing tubes at the top of the distiller. The stainless steel tubes through which the steam passes have metal fins coming off them and a fan blowing air through them. This cools the steam back down into water. By this stage we now have purified water with virtually all the chemical contaminants removed.

However there is a class of chemicals called Volatile Organic Compounds (VOCs) which pass through distillation. These are oil-like substances with boiling points below water. They might be fuel oils, they might also be things like pesticides. Distillation does not remove these. However charcoal filtration does remove them very effectively. That is why Megahome distillers have an activated charcoal filter at the end of the process. Activated charcoal has undergone a special process which increases its surface area and it is remarkably effective at removing VOCs. It does “fill up” so to speak. Which is why you need to change the charcoal filters every 30 distillations.

When the water level in the distiller gets to about 2-3mm the distiller detects this and automatically turns off.

In summary: A (Megahome) water distiller first kills biological contaminants, then removes organic and inorganic chemicals and finally removes VOCs during charcoal filtration at the end of the process. The result is pure, clean, healthy water.The resulting water has 99.9% of contaminants removed. It is which is purer than any bottled water, filtered water or water produced from the reverse osmosis process.

Does Distilling Water Remove Fluoride And Chlorine?

Distilling water using a Megahome water distiller does remove all fluoride and chlorine from the water, as well as a host of other organic chemicals, inorganic chemicals and biological contaminants; including all of the following:

Organic Chemicals:


Antibiotics, Fertilizers, Pesticides, Insecticides, Herbicides, Solvents, Growth Hormones.

Inorganic Chemicals:


Hard Water Minerals, Phosphorus, Asbestos, Selenium, Sodium, Fluoride, Iron, Lead, Mercury, Barium, Nitrates, Copper, Lead, Chlorine, Arsenic.

Biological Contaminants: Bacteria, Viruses, Cryptosporidium, Chlamydia, Giardia Cysts. Distillers kill all known biological contaminants.

By removing all of these contaminants, your water is left pure, making it much healthier and safer for you and your family to drink. The contaminants are left behind in the boiling chamber as a white/yellow crust which can be easily cleaned out.
