Distilled water has been used for centuries. Distilled water is simply water that has had any impurities removed through a process called distillation. Often used in mechanical equipment, its benefit as far as drinking it has not been determined. But, if you want distilled water for your plants or for your car battery, you can make your own with a little work.
First you need to understand what it means to distill water. Let’s just presume that any water not already distilled has tiny microscopic stuff floating around in it. This stuff might not be bad or they might not even taste bad. However, these micro molecules can create deposits when used in mechanical equipment. We want to get rid of that extra material by boiling the water and converting the water into steam. When the water boils, the stuff left over in the pot is pollutants. The steam is then run through a condenser, until it is cooled and until it becomes water once again. This water is considered as distilled.
If you want to make your own distilled water, you will need something to heat the water in. You need to have a way to capture the steam, which must be routed to a condenser made of either copper or glass where the water cools. Then you need to transfer it to a sterile container. This water has been distilled. However, in order to make sure that you got all of that extra “stuff” out, the process can be repeated a second time. The final output is purely “distilled water”.
Here’s a bit of good news. Unless you just happen to like the idea of boiling water and condensing it to make your own distilled water, you can buy it in almost any supermarket or drug store. Distilled water costs a little bit more than drinking water, but that’s because it costs more to make. While some bacteria may be considered as healthy, the idea of pure and clear water that is free of contaminants sounds good enough to drink.
