Distilled Water vs Purified Water

Last Updated on September 1, 2020

Distilled and purified water are two ways to achieve clean and safe drinking water. Let’s get right to it below.

What is Distilled Water?

The process of distillation of water is quite simple. Because most of the contaminants in your water is inorganic metals and minerals, they have a significantly higher boiling point than water. During distillation, the water is boiled and the steam is captured leaving the minerals and metals behind. The captured steam is cooled and when back in it’s liquid state, it is contaminant free water safe for drinking and cooking.

One of the best water distiller units is excellent at removing unwanted metals and minerals from your water but it is not sufficient if you have pesticides and other chemicals in your water as they have a lower boiling point than water and can be captured during the distillation process. If you have chemicals in your water, you will need further purification to remove them from your water.

What is Purified Water?

Purified water refers to water that has been filtered of all unwanted water impurities. The official definition of purified water requires dissolved solids levels of 10 parts per million or less. This level of water purity is almost always better than tap, city, well, and even spring water.

What is the difference between purified and filtered water?

As mentioned above, purified water requires a specific limit to the amount of dissolved solids found in the water. Filtered water refers to any water that has gone through a water filtration system. This includes faucet filters, whole house water filters, reverse osmosis and more.

The effectiveness of water filtration systems varies greatly and if you are seeking purified water it requires a high quality filtration system. To see our recommendations for the best water filter systems you can check the articles below.

Remember that purified water can come from any source. Whether it was originally spring water, tap water, or even lake water, once purified it is to the same exacting standard of purity no matter where it originated from. Purified water is clean and safe for drinking, cooking, and bathing. When I am purifying water at home I first run my water through my whole house water filter and then through a distillation process. While not necessary, I do large batches and keep water in my water storage containers.
